Default ? On front spring rates on 3rd gen Camaro

Having a discussion on front spring rates with rear leaf spring and cal tracs.
Guy is complaining about car is sitting low on drivers front. He wants car to look straight sitting and put 1 bbc coil spring on drivers and sbc coil spring on passenger. To me this messes up launch of car. Leave same springs on both sides and give what it needs to go straight and fast 60ft.What are others doing if car is not bent. He swears it's in rear suspension parts. Car is bbc and runs high 10s.

Jeff, it an unusual situation. And it sounds like you are in the middle of a conversation that will be difficult to resolve.IF, the car owner truly wants help, this site is a wealth of information.

Thanks Larry for the words of advice. I dont pretend to know it all, I just use my experience of what does not work. These guys build big HP motors and then dont think through suspension needs. Then question why the car spins, rear steers, wont go straight and runs in the 11's with 600HP. My bracket car Monte was built around my Ed Quay built Monte years ago and he had done so many tricks to make the car run so well down the track. I can only offer my advice and they can try it or complain I guess.

I'd start by making sure there wasn't any bind in the suspension or preload on the rear and then get the corner weights and go from there.

Looks like no binding that we have found. The suspension in back is new and lubed. Front has some basic work and has some travel but that 1 bbc coil spring has no energy for movement. I'm trying to get him to use my scales as I'm pretty sure it's a weight placement problem. Shocks are full loose just to make sure they were not holding car up.

I'm confused, you say 3rd gen Camaro and then Caltracs and leafs. 3rd gens use coils in the rear with a torque arm and 2 lwr. arms. Frts. use standard style coils only a lower control arm and struts.

Jeff,
I would look at engine placement. Most are not put in correctly and cause corner weights W/driver to be out in left field. Then there is always the chassis being square.
good luck..
