Hi,
I have the 15" RS wheels. The size isn't really the issue as the caliper fits underneath the wheel but the back face of the spokes scrape on the outside edge of the caliper. I have had to spece the wheels out by 16mm and grind a small amount off the inside face of the alloys to make them fit. As you can imagine this isn't the perfect sollution. I really want Compomotive Mo's as these look great on Mk4's but cant find anyone who can tell me whether the spokes would clear the calipers.
