Hi all, I am just new to the forum and need some advice please :/ I have put a set of 18'' Audi rs alloys on my tdi sport 140, it's a 2007 plate and I have heard of huge rims going on them but didn't want something to dramatic, I put them on and now I have problems with some sort of scraping, the car isn't lowered yet and I would like to drop it 30mm or something only I need help to stop the scraping, I think it's something in the arches because there's no marks on the underside of the car. What could this be? How do I rectify it? Any help and advice is really appreciated. Thank you.
