The fidanza flywheel is not worth the money IMHO. It is good for autocross but as far as straight line racing it has not proven any gains. I had one in for about a month had some other problems with so I took it out and send it back. Yeah it revs quick at and idle but watch your tach after youy push the clutch in going down the road shifting throught the gears. The revs don't hold. I think everyone tricks there selfs into thinking that it has more power just because they dropped 400 dollars down on the piece. I know it doesn't happen much but just think about that aluminuim flywheel shattering and coming through the bellhousing. I will stick to my one piece steel flywheel. Good kill on the gsr!
