Easy Allen...
Im new to this forum and I this is my virgin post!! I have a 98 S A3 1.8T which is running on S3 Avus 17"s. The offset is slightly different to the standard 16"s which makes the wheels sit further out in the arches than the standard wheels (pretty much flush with the wheel arch). Its not an issue though, just gives the car a slightly more aggressive stance. Not sure if anyone else has experienced it, but it made my car look higher than before too, so after a 30mm drop, I was back to square 1! Other than that, they are a direct...tasty looking fit!
If you havent found a decent set yet, im selling mine....
hit me back....
