I'm guessing you are going to use coilovers. On my car, I'm running a 4 bar with coilovers and I run the lower bar parallel to the ground and the upper bar angled down in the front. I kept lowering it until the car acted the way I wanted it to. You will know when it's wrong after you drive it around a while. Initially, I had my upper bar parallel to the lower bar. The car would just burn the hides under moderate throttle. Once I lowered the upper bar in the front, the car now squats when I hit it, an it just goes.
