Competition Clutch Lightweight Flywheel
Lightweight flywheels save weight and reduce the overall rotational mass of the engine. This will allow for faster revs with improved engine and throttle response. Because of these reasons, you will also notice an increase in both horsepower and torque.
This is a great upgrade for your race car, rally car, or even your daily driven street car. But like all modifications, there are a few caveats. Depending on what clutch kit you decide, there may be a slight increase in clutch chatter. But the performance gains always outweigh the noise.
