1000 Series Twin Disc Including Aluminum Flywheel

Well what do ya know, Toyota actually listened to everyone and released the MK5 Supra with a manual transmission! What they apparently missed however, was the fact that people are already pushing the B58 engine to the limit and making some incredible power. They equipped the car with a single disc clutch and a chunky dual mass flywheel. Well, Clutch Masters to the rescue! When you're pushing the limits of your Supra, you're going to need all the holding power you can get. It's proven these B58 engines are very potent, and capable of big power. That is where our 1000 Series Twin Disc Clutch Kit saves the day. 

The 1000 Series clutch is designed to handle well over 1000 ft. lbs of torque all the while still being street friendly thanks to it's strap driven design. The strap-driven plate design allows for smooth engagement and minimal clutch chatter while still being able to withstand hard launching, clutch kicking, and high RPM shifting.

The cover assembly is machined from billet aluminum and is then Type 3 hard anodized. Our billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing our ability on machining the strongest cover possible while maintaining minimal weight, we are basically able to eliminate any flex in the cover. Our billet covers see only .003" of flex where as a cast or stamped unit can see as much as .030" of flex. By eliminating this flex in the cover, the driver is able to operate the clutch much more consistently and confidently. All the movement being applied to the diaphragm of the clutch from the throwout bearing is used solely to engage and disengage the clutch and isn't wasted by the cover flexing first. The strength of our covers also results in greater clamping force over the same amount of area vs. a cast or stamped cover. This means our twin discs are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized.

Flywheels are made for each specific application in either aluminum or steel. Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert. Steel flywheels are machined from 1045 billet cores and are then black oxide treated for rust prevention

Our friends over at CES Motorsports recently equipped their shop Supra with our 1000 Series kit and internal hydraulic release bearing, and put together an incredible video showcasing the setup. Give them a follow to keep up to date on how far they are able to push the manual transmission in the MK5 Supra!
