    help with launch adj,

    well while I'm in the waiting pattern I have a few questions, I'm waiting for the frame man to scale my car when he gets the time, so for now a little help may help me understand all this. when your car pulls hard to the left at the launch would that be that you need to tighten the spring on the left rear. and if it pulls right you would tighten the right rear. also I've been online looking at 100's of launch's and it looks like they are all pulling the left side up a little, but mine has allways pulled the right side up about 3'' higher than the left side why would that be, even when it was pulling perfect it still came up on the right side 3'' higher This is a 2500# ladder bar 85 camaro 675 H/P 1.76 PG 5.14 gear 14x31 tires --I can't find anything that tells you what to do to correct certain problems, I figured because it could be so many things causing them no one wants to say but you have to start somewhere and I have no Idea even with all that I read It tells me nothing,
    Thanks Andy

    You don't want to mess with the springs to adjust for launch. They just hold up the car. You adjust preload in the ladder bar to make it launch straight. If the rear is square in the car and nothing is broken or worn out, it sounds like you have a bunch of unintentional preload somewhere. The scales will tell ya..........
