I replaced the classic-looking 15 inchers for some AMG split-spoke 17s (SLK32 and C32) to improve my stability and steering response. It worked, but there is a noticeably smaller gap between the rear fender and tire. I would think there would be a smaller gap in the front and larger in the rear, but oddly, it's the opposite. I did noting to the springs pr shocks, so why would this happen? I'm wondering if spring pads would help, and if so, what are your recommendations for sizes?
