hey guys, is there a way to tell if you have got an aftermarket clutch or not?, i bought my r33 gts4 round 80000kms, i was thinking about putting a heavy duty clutch in, but im not sure if i already have one in or not. I don't want to pay for labor to remove clutch to find out there was already an aftermarket clutch in there.
If i give my car a hard launch would the stock clutch slip alot?, i rev my gts4 to about 6000rpm (to test clutch) and dropped the clutch. all 4 wheels screeched a bit and i got off the line pretty quick. Also when I give my car some go and shift quickly just before red line, (1st to 2nd gear), the tyres would also screech.
Now would a stock clutch be able to do that? or does my car may already have an aftermarket clutch?
