last week i blow up the stock clutch i had a act street clutch and flywheel installed at the honda dealership. i drove back from sc and for three days everthign was fine besides normal high performance clutch chatter. i brought it to the track firday night and after my second time dropping the clutch i encountered a loud knocking noise, i first thought the rear was blow by the noise i heard, but after jacking it up i isolated the noise to the front of the transmission/clutch area. i drove the car home and heard the noise increases with rpm. and changes slighty in tone with the clutch pushed in or out, it almost sounds like metal touching metal. i pulled the tranny out and everthign looked normal but.. the clutch dick had slight play on the input shaft back and fourth. i wanted to no if anyone new the tolerances of these clutchs and how a honda clutch disc would fit on the input shaft. the tranny has no shaft play and looks to be fine the rear and the axlews seem to be fine also if you guys have any idea what the noise can be please let me know thank you-
