I have a 2000 Mustang GT, when I bought the car it has Eibach springs. I'm not sure what type of Eibach, but they are on the rear and are blue. The front looks stock still. The rear tires are being cut by the fender, my question is do i need to replace the springs or the shocks. The rear rims are FR500 18x10. Any help would be appreciated, thanks.
