How many points to run a lightened flywheel? How many point to run a multi-disk clutch?
There is also a case where a single mass conversion kits for cars that originally had an expensive and unreliable dual-mass flywheel. The kit is often cheaper than the original OEM dual mass. Also, would it be 0pts to use a lighter single mass flywheel if it was required for an engine swap and fit in the $2500 swap money?
