A performance clutch kit will allow you to drive harder under increased power levels while making sure there is nothing lost to the drivetrain. If you track your vehicle or have raised the maximum horsepower through tuning or modification, chances are you will see increased benefit by installing a high performance aftermarket clutch.
The ultimate in a racing flywheel and clutch! This was developed for use in our E36 and E46 World Challenge Touring Cars. The combined weight of the clutch and flywheel is only 11lbs!!!
This multi-disc (2 or 3 disc setups) offer a minimal flywheel mass (enough to include a factory ring gear for the starter) and a small 5.5" clutch assembly rated to 500hp. By saving as much weight as possible less energy is used in simply spinning the flywheel/clutch assembly and that means a lot more power and torque is available at the drive wheels. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines and this is among the most advanced and lightest racing clutch kits available for your BMW race car.
The JB Ultra-Light Performance racing clutch is available in 2-disc or 3-disc setups. We used the 5.5"/140mm size in our Touring Cars but larger sizes are available too. This is a turn-key racing clutch and flywheel kit that you don't have to engineer or spec yourself. This is the same clutch setup we used when winning the 2003 and 2004 Touring Car Championships - the quality and performance is unquestionable. That series also employed standing starts at each race and this clutch setup performed flawlessly with nearly a full season of racing on them before needing a change.
multi-disc racing clutch with Performance racing pressure plate
JB Racing throw-out bearing with custom bobbin This is a true racing clutch and will not function as a street-able clutch at all. It behaves as an on/off switch with no slippage allowed. Extreme care must be used when driving on to trailers and around the paddock. But when driven correctly the life span of this clutch is amazing - we could get a full season of racing a 300hp M54 from this clutch setup including standing starts at every race! Replacement clutch components and flywheel rebuilding are available.
A properly adjusted clutch stop is required for use with this clutch kit.
