One thing I noticed on the clutch is that the car uses a aluminum clutch nut. We all know when aluminum gets hot it expands. After that the clutch nut will back off and there goes that perfect clutch set-up you had. So I put the old steel one on and my clutch never changed on me during the race!!!! A little something for you guys to try..... And the ultra hard spring is the ticket.
Also I put a blue clutch shoe on it....POW!!!! off every corner.
