well i have a fidanza 7.5lbs flywheel that has been lightened to 4.5lbs, combined with a CM stage 3 clutch and im pretty retarded when it comes to driving.......i drift around the bank my work banks at.....pretty fun.... but anyways i took my tranny off this past weekend to see why it wouldn't disengage and it was my release bearing... haha shattered it... anyways with all the hell i've given my flywheel i haven't had a single warping or heating porblem out of it.. and no slips out of the clutch
