I like it.... w/ just the clutch/flywheel combo, I dropped my ET's by 0.2 and that's just dumping the clutch @ About 65-72 on V700's hitting 2.1 60's... I don't know if you Drag your R, but no matter what, it's still streetable.. You have about 1/2" of engagement (with it being a Sprung-hub 4 puck) Hell, My ExGF could drive my ACT HDR6, and she loved the CM... Besides, the Stage IV is cheaper than the stage III.
email one of my associates, his name is Steven

I actually sell CM to him, and he can get you a pretty good deal...
Good luck... Scott Boller
