Caster & Camber VS Height

My car has the slant six stock torsion bars and a 1-1/8" Addco front stabilizer bar. The car is mainly highway-driven and is never raced. Any advice about what would be good height setting so that my car is low enough to rarely bottom-out on bumps?

With the slant 6 torsion bars, if you go much lower than the stock ride height you'll bottom out the suspension frequently. If you want to lower the car any from stock, you need to increase the torsion bar size to reduce the amount of suspension travel you need to have.
