Ok i just put in a used Competion stage 4 6 puck clutch in my 240. Reused my stock KA flywheel, didnt get resurfaced because it was already really clean (seemed like previous owner had put a new one) Anyway i was wondering if i still need to do a "break in" Im sure the clutch is already broken in since it was used...but since its matted to a different flywheel now, do i still take it easy for like 500 or so miles or the surfaces may glaze?
