On the Avant I have some RS6's (7.5J, 18" with a ET54). Im on coilovers about 50/60mm. I want to get some spacers to bring the wheels out a bit as they are hiding in there. At first I was thinking 20MM rears and 15MM fronts, but after a quick messaure up with a ruler it might be close for rubbing. This is just a gestimate though as not quite accurate.
Anyone able to give some advice? R 20MM F15MM or R 15MM and F 10MM? I want them to sit flush enough to not hide but dont want them sticking out
