What can be done to reduce rotating mass on the cossi YB? I have a trackday car, 2wd sapphire cossie for drift and track use and want to make the most of what little power I have 330bhp about the same torque MAX So what is available and whats recommended? I was thinking a 7.5" flywheel and clutch is definately the lightest out there and twin plates are available, im thinking of changing to hydraulic actuation too so feel and weight isnt too important.

The clutch will be dumped often and generally used hard, it cant slip and must not cost a fortune. IDEAS?????
