Since I already have the Pedders Street II conversion I'm going to change out the OEM height springs with their plus one inch on the fronts and plus 1.5 inch on the rears. My 17" tires never rubbed but since I've had to go to 18" I'm getting some rubbing over bumps........can't have that.MARS said:What brand of springs did you buy? Did they lower the car? Thanks.
