The wheels on my 2009 A3 Sportback are the C4N option 17 x 7.5J 16-spoke two-tone design. I like the design but I am not over keen on the two-tone appearance. The seem to look dirty with brake dust even when I've just cleaned them! My previous Sportback had similar design wheels but they were just a single silver colour and looked great. I am considering having them painting silver by a specialist. I have just been looking at a the website of a company called The Wheel Specialists in Birmingham who seem to offer a good service of dropping the car off at their premises in the morning and collecting the car, all wheels painted, at the end of the day. Has anyone any experience of this company. By all accounts they have a number of branches around the country. Alternatively does anyone have any other recommendations of anyone who can provide a similar service.
