The rubbiing could just be down to your tyre choice, different makes are slightly different shapes. A friend of mine has a mk5 GTi on 19's and its lowered, when he was running Toyo Tir's there was no rubbing, he replaced the fronts with the Michelin PS2 and they rub quite badly and have damaged his arches. When you compare the tyres you can see the Michelins have a much squarer sidewall.
O yes, the wheels look mint!
