I run a ss spring car with a transbrake. car weights 3000 without me [270], I run 8lb of air in the rear running 14x32s. I put the brake in over the winter and leave on the two step at 3000rpm. I run spring clamps 3 on the right 2 on the left as per shawn jennings websight. I was thinking of staggering air pressure or mabe investing in some rancho adjustable shocks. the car pulls the front end about 6 to 12 inches on the launch with no frame twist. After launch car goes straight and true. Any input?

Check to see if your leafs aren't walking/shifting on your axle pearches.

Scale car. I would bet that you are heavier on left side rear than right. You can adjust by tightening up left torsion bar with you in car. You will need someone to help to do this.
