This is if he plans on making 250-300. It will take a fair amount of money to do that with an ls. Since he says hes not planning on modding it for a long time it should be fine with the type r or even stock clutch. If you really dont have the money then bottom line clutch needs to be replaced and the flywheel doesnt. So if you really dont have the money then just do the clutch.

However, I feel the flywheel is a great upgrade and makes the car a lot more fun. Throttle responce is a great thing. I have probalby about 10k with the type r clutch and prolite and have loved every min of it. It grabs fine and by the time i need a new one who knows if i will even still have the car or what. Maybe eventually ill have 250 hp but by then ill probably need a new clutch anyways.
