For a good drag transfer you want the suspension to transfer weight to the rear for traction.
The best way to do this and keep it streetable is adjustable shocks and struts and a quality set of control arms.
Springs can go either way and I know you want to go lower but just remember that shortens the amount of travel you can use to transfer weight.
I like the lowered look and my car tucks the tires when launching because I wanted it lowered. Just not the optimum setup
I had coilovers all around, rear control arms, sway bars, gears, k member, cc plates, exhaust, intake, tb, 305 Hoosier dr's and some weight reduction like no rear seats and lightweight sparco racing seats and light cowl hood
cut your springs....it is a great drag spring thanks to how well the stockers transfer weight....just cut a coil all the way around you'll have a car that sits nice, but better yet launches nice. also look into drag bags for the rear :good:
