My IS is on 18" alloys with 225/40 tyres, with standard suspension. when driving along good smooth roads the ride is fantastic. Stick it on country roads around Fife and I have a massive problem. The wheels are scraping on the arches, its a horrible noise to be hearing especially after putting two new front tyres on her. (Its also starting to effect the arches)
So now i ask for advise, what are my options!? how can i fix it without resorting to 17" alloys.
I'm thinking of putting coilovers on but i dont know whether these are going to solve my issues.
Please help!
Thanks
