alright, i am about 200 miles on my f1 stage 1 clutch. i am fairly satisfied, but i have heard negatives about the higher stage clutches. with the stage 1 clutch there is slight chatter and rumble if you downshift and dont speed match as with the stock clutch, the car would just slow smoothly for the most part and force the engine to rev being in a lower gear. take note though, i am not past the recommended break in period of 700 miles, so until the 700 mark i will shift more cautiously and baby it, then i will progressivly drive harder and see how she handles some aggressive driving. i hope to give a good review because it is a fairly priced clutch. my recommendation is if you have the money to make power in your vehicle increasing the hp and torque then dont skimp on the clutch and although the most expensive clutch may be overkill and sacrifice drivability, you may want to stear clear of the cheap-o clutch. i only went cheap due to being at the end of my funds which is a bad exuse but i wanted to get it done before winter so i bought something that didnt have bad nore good reviews. havent really heard nothing bad or good so i thought i would try and let everyone know what i think from first hand experience. if this clutch just plain out sucks i will let you all know.
