I'm looking to upgrade my wheels to BBS LM's. For RS4 BBS officially offers LM269 which are 8,5x19 ET20 (with BBS supplied spacer 12mm). I'd rather go wider... so BBS also makes LM279 which are 9,5x19 (also ET32). BUTTTT the problem is that BBS is not certain that I could clear the front brakes without rubbing. For tyres I'd use PSS 255x35x19. My car also has H&R springs and ARB's.
My basic knowledge of wheel fitment says that I should need about 8-10mm spacer to clear the front caliper. I've searched alot, but can't seem to find any solid info on this matter. I've found few pictures, but that's it.
Anyways the best photo which seems to have LM279 (or LM155 as they were few years ago) is:

Any gurus who could advise me?
