Do the light weight flywheel, you'll love it. I had heard all the old tales about them not being very friendly for street driving, which just didn't sound right to me, but after installing one and driving it I realized the Z drove much easier than before with the heavy stock flywheel. And in addition the car will accelerate better. John's point is, as usual, a good one.....learn to use the clutch with as little slippage as possible and it will live a normal life.
