Need some help selecting front and rear coilovers for road race and street duty. Car has 17" wheels, LS1 engine, stock brakes for now. Looking for spring rates, coilover brands ect. Also does TRZ or someone make a set of control arms for lowered cars? I know the PA arms i had on my drag car were crap due to the car being slamed to the ground, all the ball joint angles were maxed and would bind. TIA!
