it took a little bit to get it the way i wanted it….i got the fronts as well. if you do the fronts it will take longer. the car will settle a little bit also after you adjust the springs. thats what does take time . bounce it up and down and take it around the block, you will probably need an alignment too. for now the shock settings (with the knobs) i just set in them in the middle for now until i go to the track then i will change them. it does ride rough, but i have the 150lb springs in the rear. I'm sure the 130's would be better for regular driving. if it was a daily driver i would try the different springs. i have a goal of running 9 sec. this summer and I'm building a new motor now. a/c is going to work and it will have no cage…..im very happy with the stance and the way it looks, and the shocks are nice...
