It all depends on the clutch that he's using.

The 11.5/12" stuff basically requires either a McLeod steel flywheel or a McLeod/Fidanza aluminum flywheel.

The 11" stuff is all open for aftermarket flywheels and the price difference becomes about $125 difference. About $250 for a steel wheel, $375 for the Fidanza aluminum wheel.

I had an aluminum Fidanza in my Cobra after I had a 30 lb Hays and there was quite a bit of difference in how much I had to slip the clutch when taking off. That was the only thing I didn't care for.
