The launch is a mystery to me. I've never really been able to crack that nut. Most times I roll out pretty easy like a 2.4/60ft. I tried one time without traction bars on the car. Revved it up to about 4K and dumped the clutch. The car was bouncing around so much I thought I broke something. Pushed in the clutch and then let it out easy. I was relieved to find it was ok. These days I won't even give it too much pedal til the clutch is fully engaged. Even still, without track tires, the tires spin the majority of the way down the line. Can be frustrating for sure. Starts to feel like playing golf. I'll stick with my 3.23s.
