Suspension Setup on 70 Dart Caltracs &Shocks

it should Hit alot harder obviously off the line. Probably need to stiffen everything, shocks and preload on the bars. the reason the car lifts off the line is due to the suspension design which tries to push on the top side of the center of gravity. this causes the body and the rear axle to go in opposite directions. the body lifts and the rear axle Plants {goes down}. this is just the opposite of the GM A-body vehicles which squat during a launch. Sometime the effect of this could be too much of a good thing. You have to figure out how to control it. stiffening the rebound of the shock could help but experimentation is best to see what works. Drag racing is a scientific endeavor.
