let me just say if you leave the stock shocks in your car with lowering springs, your ride is going to suck big time. I did that for a week while I was being lazy and not installing my bilstein sports (btw... get sports you willl need them) and the car would just bounce all over the place, youd take a bump or even an expansion joint, and the car would bounce for like 15 seconds, it was horrible. And if you went over a speedbump etc.. the car would go up and then slam back down, bottoming out. The car will also bottom out all over the place. Trust me, you need bilstein sports all around with lowering springs...
