Exedy Performance Clutch KitsStage 1 Kits Stage 2 Kits Stage 3 Kits Stage 4 Kits Stage 5 Kits
Carolina Clutch and Performance, offers Performance Clutch Kits manufactured by Exedy, the original equipment providers for a major portion of the Japanese import car market.
Stage 1 - Single Plate Organic:
EXEDY Racing clutches with organic friction materials use only premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modified engines.
The driveability will be like a stock clutch. Pedal efforts will be higher because of the higher clamp loads. All of our clutch discs have high capacity spring center dampers to reduce the drive train shock and impact.
Stage 2 - Single Plate Cerametallic:
EXEDY performance cerametallic clutches are designed to handle the abuse of high power modified engines. Our cerametallic friction material can handle much more slippage than stock type disc assemblies without slipping and fading.
All EXEDY performance cerametallic clutch discs have spring center dampers to reduce the impact and shock loads put into the drive train. This protects the transmission and the rest of the drive line system.
We offer two types of cerametallic discs -normal thickness and reduced thickness.
The reduced thickness (thin cerametallic) discs offer greatly reduced inertia to improve shift efforts, make for faster shifting, and improve synchro durability. These discs are approximately 1/2 the thickness of a stock disc.
The normal thickness (thick cerametallic) discs have better heat capacity and therefore better durability in demanding applications such as all wheel drive. Even with the normal thickness, our three puck cerametallic discs still typically have less inertia than a stock disc.
With any cerametallic clutch system, there will be some compromise of start up driveability as compared to a stock clutch (chatter on light throttle, low rpm start up). This characteristic is generally felt to be acceptable in modified performance cars. Drivers of cerametallic clutches on the street should be warned not to "ride the clutch" to try to reduce the chatter as this will greatly increase the wear.
Stage 3 - Hyper Single Clutch:
The Exedy Hyper Single Clutch is engineered to optimize performance for cars that are moderately modified, but do not require the clutch capacity of a multi-plate clutch. Similar to our multi-plate clutches, it has a forged aluminum cover that is anodized purple. The aluminum cover is stiffer than a stamped cover and therefore allows a higher lever ratio to maintain the pedal efforts at a reasonable level.
All Exedy Hyper Clutches come with a steel flywheel and a 6-puck cerametallic facing, spring center damper disc assembly. The disc is generally smaller and thinner than the OEM disc making for lower inertia and therefore quicker, easier shifting and less wear and tear on the transmission synchros. The higher clamp load and cerametallic friction facings give approximately twice the holding torque of the OEM clutch and generally higher than other single plate clutches.
As with all cerametallic clutches, the street driveability may be marginal due to chattering and harsh engagement characteristics.
An additional feature of the pressure plate is a series of turbine-like, air flow enhancing vanes that keep the clutch cooler under extreme operating conditions to improve wear life.
Stage 4 & 5 - Multi Plate Clutch:
For high-powered applications, EXEDY offers twin and triple Multi-Plate Clutches. These are designed for hot street action as well as drag, road and rally racing.
The twin plate clutches are rated for above 500hp to 750hp. The triple plate clutches are rated for up to and over 1000hp (for drag race applications). Twins come as with both spring damper discs and solid discs. Triples are all solid discs.
All of our multi-plate clutches come with a lightweight, chrome moly steel flywheel and the famous purple anodized forged aluminum clutch cover. Depending on the application, we have both strap drive and lug drive models. All have T5001 cerametallic friction materials for extreme heat resistance.
Engine modifications e.g.. cam-timing-turbo modifications etc. cause engine pulsation and vibrations. These vibrations can cause clutch rattle when the clutch pedal is depressed by movement on the intermediate separator plate in some applications. These noises will in no way affect the performance of the Exedy Multi Plate Clutch. This rattle is well accepted in the performance industry where engine modifications have been carried out.Exedy Clutch kits include:
- Pressure Plate
- Clutch Disk
- Release Bearing
- Pilot Bearing (where applicable)
- Alignment tool.
RPS Billet Carbon Street Twin
We know you have heard about the RPS Street Twin for LS powered Corvette, Camaro, and GTO, but do you want a little more? Is taking the car to the dragstrip or road course your deal? RPS is proud to introduce its all new Billet Street Twin Carbon clutch with its â€œStraplessâ€ lightweight billet clutch cover and billet pressure plate. This design allows us to reduce the weight of the entire clutch and flywheel assembly to an incredible 25lbs with our billet aluminum flywheel or 32lbs with our billet steel flywheel. Both clutches use our special flat finger diaphragm for smooth and predicable 7000 RPM plus shifts. Our liberal use of Formula One inspired carbon-carbon friction material results in a lightweight clutch with unmatched long term durability. This clutch is rated to 900rwhp. PLEASE NOTE THAT THIS CLUTCH IS FULLY REBUILDABLE!!!RPS Billet Carbon Street Twin (Steel Flywheel) RPS Billet Carbon Street Twin (Aluminum Flywheel)
RPS Billet Triple Carbon
The RPS Billet Triple Carbon has been designed and engineered especially for the LSX powered Corvette, ZR-1, Camaro, CTSV and GTO. The Ultimate high RPM, MONSTER POWER street and race triple disc clutch is available in 6 bolt (LSX), 8 bolt (LSA), and 9 bolt (LS9) flywheel designs. Of course this clutch uses RPS's innovative "strapless" cover design and patented, non-warping carbon floater system as well as a fully CNC'd lightweight billet steel flywheel. If you have up to 1,400 rwhp, then this is the only clutch for you!! This clutch has carbon on both sides of all three discs, both floaters, as well as carbon in the flywheel and pressure plate. Weight: 36 lbs. PLEASE NOTE THAT THIS CLUTCH IS FULLY REBUILDABLE!!!RPS Billet Triple Carbon C5 Hydraulics with External Bleed Line Instructions
