It depends on what kind of driving you'll be doing. The flywheel really doesn't "make" horsepower as much as it lessens rotating mass making the engine rev faster. Sounds good, but in between shifts it winds own equally as fast. Not so great for drag racing, but excellent for road racing, due to being able to engine brake more efficiently. In a nutshell, if it's a street car, leave in the stock flywheel. That's just my opinion though. Hope this helped.

A lightweight flywheel will also make it harder to slip the clutch slowly. It will be less forgiving than with a stock flywheel.

i've read alot of ppl claiming this but i guess it really depends on driver experience. granted the combination of a light f/w along with an unsprung disk takes alittle finess to master(been there), but otherwise i've never had any problems from a standing start, even uphill. i can get started from a standstill with no more than 2k revs.

Yeah, it depends on how light you go, and how extreme your clutch is.

An aluminum flywheel with a 6-puck clutch will be a pain in the *** to slip, while a light steel flywheel with a stock-style disk will be a lot easier.

I have heard several reports latly that with aluminum flywheels with the steel starting ring (fidanza wheels) that the rings have seperated from the flywheel from the two metals heating/cooling at diffeant rates.

Maybe something outside the box to think about....

I'm currently using a findinza/exedy stage 1 combo on my a-x car, i didnt notice it at first but it did feel like i lost some low end but itll still break traction easy if i needed it too, (car is turbocharged too) its kinda neat to see the revs fly in first gear haha but it dosent happen in the later gears (looks like i need a bigger turbo or something but its plenty fast as it is)
