i ve never really delt with these old springs before but maybe you guys have. i have a customers car that is a 70 duster with a set runs mid tens its a street strip type car and has had a best of a 1.45 sixty foot . which a 3150 lbs i didnt think was too bad for a edelbrock headed small block chrysler. now heres the question since the drivers side is preloaded with the big as arch in the spring would a staggered adjustment on the shock work better. when ive stood behind the car before it sits lop sided untill it leaves the line then it levels out. now ive already tried to talk him into cal tracs and mono leafs and he want to try to get everything he can out of these. but the car at least has qa1,s all around with six cyliners torsion bars in the front. just wondering what you guys thought about staggered shock settings in the rear .

I am not 100 % .........I think it could be done , but I'd check the foot print and watch the launch.
It it stripes the surface evenly and leaves straight , I think that everything is doing it's job.

i know somebody has tried this ?

I have seen more than a few posts my guys that have do it and it worked out great for them.
