ive just had golf mk3 gti lowered 40mm on koni ssk and it handles like an absolute dream ,plus i have 17's with 205-40-17 tyres, however, if any body is in the back - even the lightest of people, the wheels will rub the trim slightly around the rear arches. this happens if i hit any bumps or dips in the road. this is proving to be a nightmare, and i assume could be quite dangerous? ive heard people talk about having the arches rolled, will this help? is it costly? what does this mean exactly and last of all where would i get it done? thanks
