here is the way I launch (took a while to get it right)
rpms to 1300-1500
clutch
slightly lifted off the floor (1-2 inches)
on 3rd amber release clutch smoothly while feeding gas evenly(practice practice practice is the only way to get it without spin)
The other way I use is not good for the clutch...I ONLY DO THIS ONCE IN A WHILE...
rpms to 3500
clutch off the floor about 1-2 inches
slowly let out the clutch allowing slippage so you dont spin em...
Shift points vary for each car but the general rule is 5200-5500
