Last Saturday I did two hard launches back to back and the car felt fine. When I went to turn around and accelerate on the return road the clutch slipped. I have heard that after a kevlar clutch slips you can let it cool down and it will be fine. I have driven the car since but I am hesitant to push it to hard. BTW, the clutch only has 4500 miles on it and was broken in properly for 500 miles and it is a full faced not a puck clutch.........thanks
