I am having problems with the back wheels rubbing on the inner wheel wells and was reading about the spacers. I spoke with my dealer about getting them installed but he mentioned he couldn't install any aftermarket parts for safety reasons.<p>For the people that have had spacers installed did you do it yourself or take it to a shop? I've got F1's with 17" pegs. I rubbed with the rossos also. Mostly when I have more weight in the car.<p>Thanks!
