i need new suspension and i need it bad. but i cannot afford tires, koni suspension, springs, and brakes all at the same time. I do plat to lower it, that is why i want the koni FSD, will it be good on stock springs? i suppose yes but i just want to be sure. also i have stock 17's x 7.5 wheels. what is a good spacer to use to get that flush look? 25mm all around?
