Suspension/chassis set up

[z28rob18]

Hey guys it's been a LONG time. After about 6 years the cars done besides tuning and testing. I've been lurking for awhile especially with the shootout coming up I'm working toward making it there. My question is about suspension tuning/scaling if anyone has any kind of info or a good read about it for our torque arm cars. I read about 4 link and ladder bar cars but there's not as much adjustability in the rear besides LCAs but even info on front end ride heights might help. I work on dirt late models now and help scale them once a week but don't know what to look for in a drag car. Thanks for any help

I've not set many torque arm setups up but I've always felt the same rules applied as far as the geometry is concerned. You have the 2 lower control arms, and if you imagine the top and bottom of the torque arm at the rear end being your other 2 points of contact and intersecting at a single point you can plot out your center of gravity and anti-squat. The only difference I see is that your torque arm mounts at the differential don't articulate like a 4 link.

Anyone run the QA1 rear coil overs? What spring rate would you recommend for drag racing? Also any info on spohn rear drag bar set up?
