Ok, sent an email this morning to 'Archenemy' and it turns out.... they are pretty clueless. There website states how easy pulling/flairing audi A4 arches. But the email responding to my queery stated that they had 'little experience' with my car, and could only probs pull 5mm (what the f**k is the point in that!?
Anyhow, I am currently on the hunt for a good looking set of universal arches as a4 ones dont exist. Ideally I want them to attach via the little lip on the inside of the arch (dont know if this is possible) or attach them via a solvent that doesnt harm paintwork (perhaps the stuff badges are stuck on with?) Anyhow, here is a little photopoop.. its sh!te but gets my point accross.
EDIT:
Would early allroad arches fit? They certainly look better
