Well im getting ready to replace the clutch in my 89 hatch. Stock on is pretty beat and is no longer holding up to the abuse. Was planning on going with a aluminum flywheel, but after looking around. I began thinking. Aluminum would warp pretty easy rite? I drive my car daily, it sees the track every once and awhile and some street. Can someone help??? Aluminum or steel?? Any input would be greatly appreciated.. Thanks
