Wheel spacers may or may not fix your problem. When you put on spacers it should help your spring/frame rub but will put you tire out 2", increasing the arch that it turns about. That may put you into rubbing fenders, bumpers, etc.... Also check your wheel location at full compression on all 4 corners. Wheel spacers may move the wheel out to far and cause it to compress into the fender while under compression...

BTW, If you do determine that you need wheel spacers, many of our vendors here on Zukiworld can hook you up.
