You are sitting in your ride at a crowded intersection          and your foot is firmly holding the clutch pedal to the floor.          When the light turns\u00a0green, you plan to annihilate the rear          tires on your car. You know your car can do it, you\u2019ve got          enough horsepower to immediately turn your tires into asphalt          crayons. When the light does turn\u00a0green, you slide your left          foot off of the clutch pedal and smash the throttle. But for          some reason, something doesn\u2019t seem right. You see smoke          billowing from under your car, but the smell is different. It          doesn\u2019t smell like tire smoke. At that moment, you see a\u00a0guy          taking\u00a0video of you smoking your car\u2019s\u00a0stock clutch instead of          the tires. You, my friend, are about to go viral on YouTube as          an epic fail.<\/p>\n<div class=\"wp-caption aligncenter\" id=\"attachment_648110\"          style=\"background-attachment: scroll; background-clip:          border-box; background-color: transparent; background-image:          none; background-origin: padding-box; background-position-x: 0%;          background-position-y: 0%; background-repeat: repeat;          background-size: auto; border-bottom-color: rgb(71, 71, 71);          border-bottom-style: none; border-bottom-width: 0px;          border-image-outset: 0; border-image-repeat: stretch;          border-image-slice: 100%; border-image-source: none;          border-image-width: 1; border-left-color: rgb(71, 71, 71);          border-left-style: none; border-left-width: 0px;          border-right-color: rgb(71, 71, 71); border-right-style: none;          border-right-width: 0px; border-top-color: rgb(71, 71, 71);          border-top-style: none; border-top-width: 0px; box-sizing:          border-box; max-width: 930px; width: 930px;\"><a  href=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_16-22-08.jpg\"            rel=\"shadowbox[sbpost-911060];player=img;\"            style=\"background-color: transparent; box-sizing: border-box;            color: rgb(243, 113, 48); display: block; text-decoration:            none;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1189129 size-large\"              style=\"border-bottom-color: rgb(243, 113, 48);              border-bottom-style: none; border-bottom-width: 0px;              border-image-outset: 0; border-image-repeat: stretch;              border-image-slice: 100%; border-image-source: none;              border-image-width: 1; border-left-color: rgb(243, 113, 48);              border-left-style: none; border-left-width: 0px;              border-right-color: rgb(243, 113, 48); border-right-style:              none; border-right-width: 0px; border-top-color: rgb(243,              113, 48); border-top-style: none; border-top-width: 0px;              box-sizing: border-box; display: inline; height: 620.48px;              max-width: 930px; vertical-align: middle; width: 930px;\"              alt=\"959-Burned-Clutch-Pressure-Plate (1)\"  src=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_16-22-08-640x427.jpg\"              data-lazy-loaded=\"true\" height=\"427\" width=\"640\"><\/a>          <\/p>\n<p class=\"wp-caption-text\" style=\"background-attachment: scroll;            background-clip: border-box; background-color: transparent;            background-image: none; background-origin: padding-box;            background-position-x: 0%; background-position-y: 0%;            background-repeat: repeat; background-size: auto;            border-left-color: rgb(243, 113, 48); border-left-style:            solid; border-left-width: 4px; box-sizing: border-box; color:            rgb(106, 106, 106); font-size: 16px; font-weight: 700;            line-height: 24px; margin-bottom: 15px; margin-left: 0px;            margin-right: 0px; margin-top: 20px; padding-left: 15px;            text-align: left;\">You have smoked your clutch and the            pressure plate looks bad.

The following is          a brief synopsis of clutch materials available, and when each          should be employed.\u00a0When it comes to a clutch material for          racing, Neal says, \u201cWe typically recommend a\u00a0sintered-metallic          (bronze) material. This has a very high coefficient of friction          with manageable driving characteristics. For street-performance          clutches, we offer organic (rag type) materials for a more          street-friendly driving experience that delivers race-type          friction capability.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Organically            Speaking<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">Organic material is          primarily used to make stock-style clutch discs. Organic          material is acceptable\u00a0for normal driving conditions and usage,          but as operating temperatures rise, or you place the clutch          under heavy loads (which is usually accompanied by slippage),          the clamping ability will fade because the coefficient of          friction drops off. In addition, at high RPM\u00a0and\/or when the          disc gets hot, they tend to fail structurally.<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Bullet Proof<\/strong><\/p>\n<div class=\"wp-caption alignright\" id=\"attachment_648033\"          style=\"background-attachment: scroll; background-clip:          border-box; background-color: transparent; background-image:          none; background-origin: padding-box; background-position-x: 0%;          background-position-y: 0%; background-repeat: repeat;          background-size: auto; border-bottom-color: rgb(71, 71, 71);          border-bottom-style: none; border-bottom-width: 0px;          border-image-outset: 0; border-image-repeat: stretch;          border-image-slice: 100%; border-image-source: none;          border-image-width: 1; border-left-color: rgb(71, 71, 71);          border-left-style: none; border-left-width: 0px;          border-right-color: rgb(71, 71, 71); border-right-style: none;          border-right-width: 0px; border-top-color: rgb(71, 71, 71);          border-top-style: none; border-top-width: 0px; box-sizing:          border-box; float: none; max-width: 930px; width: 930px;\"><a  href=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_13-52-49.jpg\"            rel=\"shadowbox[sbpost-911060];player=img;\"            style=\"background-color: transparent; box-sizing: border-box;            color: rgb(243, 113, 48); display: block; text-decoration:            none;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1189118 size-large\"              style=\"border-bottom-color: rgb(243, 113, 48);              border-bottom-style: none; border-bottom-width: 0px;              border-image-outset: 0; border-image-repeat: stretch;              border-image-slice: 100%; border-image-source: none;              border-image-width: 1; border-left-color: rgb(243, 113, 48);              border-left-style: none; border-left-width: 0px;              border-right-color: rgb(243, 113, 48); border-right-style:              none; border-right-width: 0px; border-top-color: rgb(243,              113, 48); border-top-style: none; border-top-width: 0px;              box-sizing: border-box; display: inline; height: 620.48px;              max-width: 930px; vertical-align: middle; width: 930px;\"              alt=\"$(KGrHqR,!jgE5HCzcoLOBOYu!ILw4w--60_57\"  src=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_13-52-49-640x427.jpg\"              data-lazy-loaded=\"true\" height=\"427\" width=\"640\"><\/a>          <\/p>\n<p class=\"wp-caption-text\" style=\"background-attachment: scroll;            background-clip: border-box; background-color: transparent;            background-image: none; background-origin: padding-box;            background-position-x: 0%; background-position-y: 0%;            background-repeat: repeat; background-size: auto;            border-left-color: rgb(243, 113, 48); border-left-style:            solid; border-left-width: 4px; box-sizing: border-box; color:            rgb(106, 106, 106); font-size: 16px; font-weight: 700;            line-height: 24px; margin-bottom: 15px; margin-left: 0px;            margin-right: 0px; margin-top: 20px; padding-left: 15px;            text-align: left;\">Kevlar material does make a clutch \u201cgrab,\u201d            and may not be the perfect choice for a daily driver.<\/p>\n<\/p><\/div>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">The use of Kevlar          material offers a much higher coefficient of friction than          organic material, but with some loss in drivability (i.e. it          gets grabby when releasing the pedal). This occurs, because, as          the coefficient of friction goes up in the disc material, so          will the aggressiveness of the material when the clutch is          engaged. This usually results in clutch \u201cchatter.\u201d Since Kevlar          is compatible with stock flywheels and pressure plates, it makes          a good upgrade choice, but using it takes some getting used to          in regards to driveability.<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Aggressive            Grabber<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">Bronze-metallic          materials are the most aggressive materials in regards to clutch          friction.

It          engages smoothly, wears well, tolerates the heat, and has a          consistent coefficient of friction. This enables us to create          clutch kits that accomplish everything for our customers.\u201d<\/p>\n<div class=\"wp-caption alignleft\" id=\"attachment_648037\"          style=\"background-attachment: scroll; background-clip:          border-box; background-color: transparent; background-image:          none; background-origin: padding-box; background-position-x: 0%;          background-position-y: 0%; background-repeat: repeat;          background-size: auto; border-bottom-color: rgb(71, 71, 71);          border-bottom-style: none; border-bottom-width: 0px;          border-image-outset: 0; border-image-repeat: stretch;          border-image-slice: 100%; border-image-source: none;          border-image-width: 1; border-left-color: rgb(71, 71, 71);          border-left-style: none; border-left-width: 0px;          border-right-color: rgb(71, 71, 71); border-right-style: none;          border-right-width: 0px; border-top-color: rgb(71, 71, 71);          border-top-style: none; border-top-width: 0px; box-sizing:          border-box; float: none; margin-right: 10px; max-width: 930px;          width: 930px;\"><a  href=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_14-01-04.jpg\"            rel=\"shadowbox[sbpost-911060];player=img;\"            style=\"background-color: transparent; box-sizing: border-box;            color: rgb(243, 113, 48); display: block; text-decoration:            none;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1189121 size-large\"              style=\"border-bottom-color: rgb(243, 113, 48);              border-bottom-style: none; border-bottom-width: 0px;              border-image-outset: 0; border-image-repeat: stretch;              border-image-slice: 100%; border-image-source: none;              border-image-width: 1; border-left-color: rgb(243, 113, 48);              border-left-style: none; border-left-width: 0px;              border-right-color: rgb(243, 113, 48); border-right-style:              none; border-right-width: 0px; border-top-color: rgb(243,              113, 48); border-top-style: none; border-top-width: 0px;              box-sizing: border-box; display: inline; height: 620.48px;              max-width: 930px; vertical-align: middle; width: 930px;\"              alt=\"2313_1\"  src=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_14-01-04-640x427.jpg\"              data-lazy-loaded=\"true\" height=\"427\" width=\"640\"><\/a>          <\/p>\n<p class=\"wp-caption-text\" style=\"background-attachment: scroll;            background-clip: border-box; background-color: transparent;            background-image: none; background-origin: padding-box;            background-position-x: 0%; background-position-y: 0%;            background-repeat: repeat; background-size: auto;            border-left-color: rgb(243, 113, 48); border-left-style:            solid; border-left-width: 4px; box-sizing: border-box; color:            rgb(106, 106, 106); font-size: 16px; font-weight: 700;            line-height: 24px; margin-bottom: 15px; margin-left: 0px;            margin-right: 0px; margin-top: 20px; padding-left: 15px;            text-align: left;\">Using a bronze-metallic clutch disc will            cause the pressure plate and flywheel to wear much faster than            organic materials.<\/p>\n<\/p><\/div>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">By reducing static pedal          pressures, usage of metallic materials can result in a quick and          clean clutch engagement. Since metallic materials\u00a0are the most          aggressive materials available, it will also wear the flywheel          and pressure plate surfaces much faster. Therefore, they should          only be used with a steel or nodular-iron pressure plate and          flywheel. If used on the street, this material will cause          chatter when the clutch is being engaged.<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Iron Age<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">Sintered iron is an          optimal choice\u00a0for street use, as it has a greater ability to          withstand slippage and not lose its friction coefficient.          Sintered iron is also preferable\u00a0for high-horsepower          applications and drag racing. When it comes to choosing the          clutch material for your car, Norton explains, \u201cWe actually have          particular materials for particular setups. For instance, we do          not have one, two, or even three preferred materials. However,          our Stage II-Plus carbon\/Kevlar hybrid materials and our Stage          III-Plus materials are the most recommended in high-horsepower          environments. Likewise, our organic and pure Kevlar materials          are the most recommended for mild-power applications.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\"><br \/>          <\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\"><br \/>          <\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Checking On            Twins<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">Not only do you have to          choose\u00a0what material your clutch disc is comprised of, but you          also need to decide if you need one, two, or more discs.          Clutches are generally rated by their torque-holding capacity. A          single-disc clutch will inherently have less holding capacity          than a twin disc when based solely on their surface area.          According to Norton, \u201cWe recommend installing a multi-disc unit          when using a single-disc clutch is insufficient. If the clutch          works but experiences significantly-reduced wear life, it is          insufficient. There are also cases where a single-disc might          seem sufficient, but the overall setup can benefit from a          smaller-diameter, multi-disc unit to deliver better shifting          capabilities or a lower inertia flywheel package for significant          rate of RPM and horsepower gains.\u201d<\/p>\n<section class=\"group-caption group-caption-rendered\"          style=\"background-attachment: scroll;

Twin-disc clutches also tend to be noisier in          comparison to their single-disc counterparts. This is because          there are more plates and separator discs in the package. Gerko          tells us, \u201cThe main goal of a multi-disc clutch is to increase          clutch surface area without substantially increasing pedal          effort.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">A good rule of thumb is          that a single-disc clutch is a good all-around performance          clutch to use with\u00a0a stock or mildly-modified engine. Depending          on the clutch material used, it will have OE-like engagement and          shifting qualities. Twin discs are designed to handle a lot more          torque than a stock or aftermarket single disc, and therefore          are a better fit in higher horsepower applications.\u00a0To make the          right choice, you will need to know the torque capability of          your engine, and consult the clutch manufacturer.<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\"><br \/>          <\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\"><br \/>          <\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\"><br \/>          <\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">Weighted            Rotation<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">When talking clutches,          you have to factor in the flywheel. The flywheel not only has          the teeth for starter engagement, it is also an energy-storing          device. A heavy flywheel causes the engine\u2019s RPM to climb at a          slower rate than a lighter (aluminum) flywheel, but since it          also stores more energy because of its mass, the engine\u2019s RPM          will not drop as dramatically (like between shifts) as if using          an aluminum flywheel.<\/p>\n<section class=\"group-caption group-caption-rendered\"          style=\"background-attachment: scroll;

An aluminum flywheel is lighter, and when used, the engine            will not have as much rotating mass and will lose RPM much            faster when shifting,<\/p>\n<\/section>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">Also, a lighter flywheel          will allow the engine to spin quicker, but a more dramatic drop          in RPM\u00a0will be noticed (like between shifts), and the lighter          weight could also cause an issue if using your car for daily          transportation. This is because the lower inertial mass of the          lighter flywheel means the car will be harder to get moving from          a stop sign or traffic light. Aluminum flywheels are generally          used in road or drag race applications where the engine is          continually kept at a higher RPM.<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">\n<div class=\"photo-with-content\" style=\"box-sizing: border-box;          display: table; font-size: 14px; line-height: 18px;          margin-bottom: 30px; width: 930px;\">\n<div class=\"photo-content\" style=\"background-attachment: scroll;            background-clip: border-box; background-color: rgb(222, 222,            222); background-image: none; background-origin: padding-box;            background-position-x: 0%; background-position-y: 0%;            background-repeat: repeat; background-size: auto; box-sizing:            border-box; padding-bottom: 0px; padding-left: 30px;            padding-right: 30px; padding-top: 0px;\">\n<h4 class=\"photo-content-title\" style=\"background-attachment:              scroll; background-clip: border-box; background-color:              rgb(204, 204, 204); background-image: none;              background-origin: padding-box; background-position-x: 0%;              background-position-y: 0%; background-repeat: repeat;              background-size: auto; box-sizing: border-box; color:              rgb(243, 113, 48); font-family: Nobile,Arial,sans-serif;              font-size: 20px; font-weight: 700; line-height: 22px;              margin-bottom: 31px; margin-left: -30px; margin-right:              -30px; margin-top: 0px; padding-bottom: 17px; padding-left:              30px; padding-right: 30px; padding-top: 17px;\">What Is              Moment of Inertia<\/h4>\n<p style=\"box-sizing: border-box; line-height: 24px;              margin-bottom: 15px; margin-left: 0px; margin-right: 0px;              margin-top: 0px;\">The moment of inertia (MOI) is the              measurement of an object\u2019s resistance to changes in its rate              of rotation.\u00a0MOI is a huge factor when designing clutches.              This is\u00a0because in order to accelerate a vehicle, you first              need to overcome the vehicle\u2019s resistance to acceleration \u2014              its moment of inertia. Reducing the MOI has the same effect              as adding power to the engine. A small change in the              diameter of a clutch has a dramatic effect on MOI. For              example, an increase in diameter from 7.75 inches\u00a0to 11              inches, equates to approximately doubling the MOI.\u00a0This              difference requires almost\u00a0doubling the power required to              accelerate this clutch.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"> <strong            style=\"box-sizing: border-box; font-weight: 700;\">Under            Pressure<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">The pressure plate of          your clutch system is what applies the clamping force that          squeezes the clutch disc against\u00a0the flywheel. But just like          with the flywheel and clutch disc, you have a choice to make.          For this article, we\u2019ll focus on the three main types of          pressure plates: the long style, the Borg and Beck, and the          diaphragm. According to Gerko, \u201cThe diaphragm-spring clutch          really is a superior design, because the clutch can be designed          to steadily increase its clamping load as the disc(s) wear. This          is tremendously beneficial in multi-disc applications. It helps          the customer get the maximum performance from the clutch before          it needs replaced.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">        <\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">        <\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">The long-style pressure          plate is identified by the three thin fingers that contact the          throw out bearing. The long-style pressure plate is typically          used in drag race applications, and will deliver\u00a0a          considerably-hard pedal feel. The Borg and Beck style is similar          to the long style in that it\u00a0functions via three fingers, but          the difference is it has wider fingers that release plate          pressure. According to Neal, \u201cThe long-style design is great for          high-horsepower applications like drag racing.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><a  href=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_14-39-11.jpg\"            rel=\"shadowbox[sbpost-911060];player=img;\"            style=\"background-color: transparent; box-sizing: border-box;            color: rgb(243, 113, 48); display: block; text-decoration:            none;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1189126 size-large\"              style=\"border-bottom-color: rgb(243, 113, 48);              border-bottom-style: none; border-bottom-width: 0px;              border-image-outset: 0; border-image-repeat: stretch;              border-image-slice: 100%; border-image-source: none;              border-image-width: 1; border-left-color: rgb(243, 113, 48);              border-left-style: none; border-left-width: 0px;              border-right-color: rgb(243, 113, 48); border-right-style:              none; border-right-width: 0px; border-top-color: rgb(243,              113, 48); border-top-style: none; border-top-width: 0px;              box-sizing: border-box; display: inline; height: 593.79px;              max-width: 890px; vertical-align: middle; width: 890px;\"              alt=\"Clutch-7\"  src=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_14-39-11-640x427.jpg\"              data-lazy-loaded=\"true\" height=\"427\" width=\"640\"><\/a>The          Borg and Beck style uses rollers under the pressure plate cover.          These rollers are forced outward under centrifugal force as the          engine spins. This increases the clamping pressure as\u00a0the engine          RPM increases. Finally, a\u00a0diaphragm pressure plate uses a series          of \u201cfingers\u201d (also called a Belleville spring), that completely          encompass the center opening of the pressure plate. The main          advantage to this style pressure plate\u00a0is that holding the          clutch pedal down at a stoplight is much easier than with a long          or Borg and Beck-type pressure plate. \u201cWe almost always prefer a          diaphragm unit.\u201d says Norton, \u201cDiaphragm clutch technology is          superior for the majority of uses. Diaphragm units produce more          clamp load, more of the time, with friendly pedal requirements          and high RPM capability. Diaphragm pressure plates are also a          no-maintenance option.\u201d<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><strong            style=\"box-sizing: border-box; font-weight: 700;\">The Choice            Is Yours<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">So which flywheel,          pressure plate, and clutch material do you think you need now          that you\u2019ve smoked your clutch and become a YouTube favorite?<\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\"><a  href=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_15-07-44.jpg\"            rel=\"shadowbox[sbpost-911060];player=img;\"            style=\"background-color: transparent; box-sizing: border-box;            color: rgb(243, 113, 48); display: block; text-decoration:            none;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-1189128\"              style=\"border-bottom-color: rgb(243, 113, 48);              border-bottom-style: none; border-bottom-width: 0px;              border-image-outset: 0; border-image-repeat: stretch;              border-image-slice: 100%; border-image-source: none;              border-image-width: 1; border-left-color: rgb(243, 113, 48);              border-left-style: none; border-left-width: 0px;              border-right-color: rgb(243, 113, 48); border-right-style:              none; border-right-width: 0px; border-top-color: rgb(243,              113, 48); border-top-style: none; border-top-width: 0px;              box-sizing: border-box; display: inline; height: 593.79px;              max-width: 890px; vertical-align: middle; width: 890px;\"              alt=\"0809phr_01_z+clutch_play+clutch\"  src=\"http:\/\/cdn.speednik.com\/wp-content\/blogs.dir\/1\/files\/2015\/08\/2015-08-13_15-07-44-640x427.jpg\"              data-lazy-loaded=\"true\" height=\"427\" width=\"640\"><\/a><\/p>\n<p style=\"box-sizing: border-box; line-height: 24px;          margin-bottom: 15px; margin-left: 0px; margin-right: 0px;          margin-top: 0px; padding-bottom: 0px; padding-left: 20px;          padding-right: 20px; padding-top: 0px;\">At this point, we have          hopefully shed some light on choosing the correct clutch.
