How To Tell If You Got An Aftermarket Clutch

[OoskylineoO]

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?

sounds like your clutch is working perfectly.

a slipping clutch is when the power isn't making to the wheels which doesn't sound like your problem

as above - clutch seems to be doing exactly what it should - leave it alone

if its doing its job then let it be. if you decide to reach a higher power level and it starts to slip, then replace it.

yea agreed. mine had a stock clutch and i gave it hel and it lasted till 98000kms...then it snapped in half. mind you i brought the car with 50000 on it but they work fine. i have an excedy ceremic clutch now and there isnt much difference to tell you the truth beside you can chirp 3rds without a problem
