I run the omnipower drag coilover setup. It uses their regular coilovers up front (10k springs I think) and I believe 18k springs in the rear. Also running orijin solid bushings in the front lower control arms which helped alot with wheel hop. The car launches really well now. A few of my friends that are really hardcore drag racers have driven it and said its the best car they've ever felt on the launch. It's pretty stiff on the street though. I guess it just depends on your tolerance. I daily drive it about 500 miles per week...
