What 8ight clutch shoes would you guys get for maximum life/miniman wear? Right now the have the KH 7075 alum in my cart at amain with green and gold springs, but I was wondering if the Dynamite Max-Life shoes last longer? This will just be for practicing at tracks and want long life out of them. They came with 4 aluminum shoes and I thought it bate alot of bite even though the seller said the clutch shoes were really worn.
