Blue Pig,

I'm having a hard time grasping what you are saying. Traction is all about weight transfer. The more weight you can transfer to the rear at launch, the better. This is the reason for 90/10 drag shocks. The let the front rise quickly and the rear end squat and keep them there for awhile. Traction is directly proportional to your coefficient of static (and dynamic) friction and the normal force on the rear wheels. The best launch you could ever have would see your front wheels SLIGHTLY off of the ground. This will give 100% of the vehicle's weight applied to the rear wheels, without wasting kinetic energy by lifting the front wheels way up. This is also why the old "gasser" type cars with the solid front axle were so tall in front, because the weight transfer was easier. Gosh, I knew that dynamics class was good for something!!
