Best way i have found is by whats called "slipping the clutch" Just start out with your natural starting RPMs (im around 4,4500) and when its time to GO let out on teh clutch some so it engages just enough w/out spinning the tires. It takes alot of time to get used to because you have to go only by the way the car "feels" but if you can master it you can lauch with damned close to full boost and no tire spin followed by some decent rubber while hitting second
