Hi, the S3 failed it's MOT today, they said my 18" RS4 reps were rubbing on the inside of the front arches on full lock. I did think that they sat further into the arches than the 17" Avus rims. Has anyone else had this problem? Don't know what the offset of the 18"s are, would need to take one off & see if it's stamped in the back of it. Would fitting spacers cure my inner arch fouling ? I'm going to book it in soon to get the suspension done, so I could get them to fit spacers at the same time. Thanks, Scott.
