Whats the body... but it sounds like a A-body... most likely in the 120-130 pound range... if you knew the rear weight it would be easier and maybe closer

I'm getting ready to do a ladder bar set up in my duster, getting rid of the complete Calvert setup just for more consistency, have all the parts including QA1 double adjustable coil overs, haven't gotten the springs yet. Just curious what people are using for a spring weight? The car is small block powered and launches with a tranz brake at 3500 rpm, runs mid to low 10's. Weight of the car on the starting line is 3130. Thanks in advance!
Depends on how much sprung weight is on the rear and where the shocks are mounted. My bet is at your weight it would like 110lb springs. The next step up is 125/130lb springs depending on what brand springs you're using. I run 125lb on a 3340lb B-Body. The car hooks very well on 10.5 tires
