I have a 9lb Fidanza and stage 2 clutchmasters clutch in my car currently. It was worth the money in my opinion. It has good mid-range pull, 1st and 2nd gear are noticeably quicker, but it's still not enough to pull on a Civic SI on the interstate. I've broken 2 engine mounts since I got it. I broke the Front mount(on the passenger side above the crank pulley)just recently on my first pass with it at the strip. Needless to say, I didn't get a good run in. It'll chirp 2nd gear without powershifting or dumping the clutch. The clutch/flywheel combo cost a little less over $600. Well worth it in my opinion.
