I've gone for stripes just on the bumpers on this one, i think stripes, red badges and red calipers make it look different from the ave black gti but not too brash.
Ive also thought about wider wheels but keeping the OEM look, because the rx2 sit in the arches too much, you could always stick mk4 anni alloys on, but they are 17's and look too big imo, i also thought so bbs lm's look similar but im not sure you can get them in 16's. i have seen some 17inch bbs rx's as well in ebay now and again, but i don't want bigger i want wider.
