my st has got 18in momo fxl-one alloys with 235x35x18 tyres on the wheels catch the arches over big bumps, i noticed that the auto leveler or what ever it is has come off, looks like a drop link, would that have anything to do with it, also can i adjust the height slightly by adjusting the drop links or is there any way to make the front a bit stiffer without forking out for suspension or stop the rubing without changing the tyres ?
