Stage 2: Street, Drag, Pulling, Autocross
Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity.Best for street, drag, pulling and autocross.
Stage 2+: Street, Drag, Pulling, Autocross
Features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the 2+ offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rallye and drift.
Stage 3: Street, Drag, Pulling, Autocross
Features a carbon semi-metallic 6 puck sprung or unsprung hub disc that has been the leading puck clutch in drivability, life and torque capacity. This unit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity. (sprung version) The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Also available in 3 puck configuration. Great for street, drag, road racing, pulling, rallye and drift.
Stage 3+: Street, Drag, Pulling, Autocross

We are here to help you find the primo clutch and since are probably “GOOGLING” clutches and have reached this page, then you doubtless have already decided you want a new clutch or new clutch component. The reasons for your search efforts can be myriad; such as not enough friction to hold your clutch and it has started slipping, or you smell a "burning" clutch, or your clutch may not be engaging when you push it in, or you may just be having a hard time pushing the pedal; or, much more gratifying , you are engaging in the wonderful sport of racing or drag racing and know you unequivocally need a high caliber performance clutch. All of the constant shifting that racing demands can be brutal on a clutch and performance drivers respect a clutch that instills confidence in the fact that they can meet the aggressive shifting demands of racing. Only an exceptionally high grade performance clutch can meet those requirements because they are the sole ones that can accommodate the power levels and temperatures inflicted on a clutch when on the track or doing performance driving. Because performance clutches generally utilize heavier springs and premium disc materials you are guaranteed a clutch that has exceptional clamping force and won’t hesitate to grab when it is critical to do so and that it will accomplish this quickly. Never fear, if you are not racing we know you are still entitled to a clutch that is smooth to operate, long lasting and an improvement over most factory installed clutches so that your driving experience is blue-chip. There are some essentials you need to bear in mind when deciding on a performance clutch and we are here to give you some information that you can utilize in making that significant decision.
First know there are three varieties of disk clutches, single (which is probably what you have from the factory) with a single friction disc working the pressure plate and flywheel, dual with an extra friction disc and a set of surfaces labeled a floater, triple discs with three friction discs, with torque capacity increasing with the number of discs from double to nearly two hundred percent. Next, the composition of the material in the clutch is of significant importance and your driving demands play a factor in making this decision. You should seek out the clutch with the latest in technological advances when it comes to disc material since previous clutch disc materials have been eclipsed by the new composites. Then there is the manufacturer and because we have incontrovertible confidence in them we would like to introduce you to SPEC, a inimitable company and one of the foremost designers and fabricators of clutches today, who can accommodate your clutch demands by presenting you with a plentitude of choices.

Their street high performance and racing clutches and flywheels are manufactured in multitudinous Clutch Kits, from street kit Stage 1,2,2+, 3, and 3+ to Race Kits Stage 4 and 5 and the SPEC Super Twin with TQ ratings of over 1500 FT TQ!
