Hi from a Newbie! Ive always had german cars except for a Lexus about 5 years ago, but since then had VW, Merc, Porsche. Finally got round to ordering an A3 Sportback 1.9tdie Sport in Ibis White, debadged with a few toys etc. I really dont like the alloys on it, so want to change them from 17 to 18 inch. Preferably black ones. Ive had a good look on here and found a few different ideas, but is it simply a matter of taking the 17s off and putting 18s on or do I need to alter anything else? Thinking of getting the windows tinted too. Possibly get them done at the same place. Will post some pics when done!
