As in the title really chaps.
I'm about to change my current AMG 345 mm front rotors to 352 x32 two piece rotors but retaining my trusty 18z's.
I recall a while back a link to a guy selling the adapter bracket to permit the fitting of larger rotors to the b7 with 18z calipers , but its disappeared and a web search has not come up with the link either.
By some chance does anyone know of the website or what the link was, I could really use it asap as I want to get the new rotors here mid next week if at all possible.

any help would be very good chaps.

An adaptor to move the caliper 3.5mm?? Is it even possible to make one that small??

Buy a set of Girodiscs or if req'd get your 352's turned down a bit
 
To be honest chaps I just couldn't for the life of me remember what the format was when going larger diameter with the 18z's , I recall a while back seeing a link to some adapters but like you say , they would have to be very small , well probably to small to even work bearing in mind the 3.5mm difference.....
Maybe I had the 8 pots Brembo's still in my head with larger discs that I was looking at recently, anyway so 352mm will just squeeze in then.

Yes they should mine are 350mm I just adjusted the pads so they run on edge of disc and leave no lip
Just watch the outer pad mine ran very close to ally bell another reason I altered pad to save the expensive bell
Good luck rob I’m sure you’ll sort it

It would be the 8 pot RS ones as they are radially mounted so easy to space.
I had them spaced to run 380mm discs on my old avant.

I think it was the 8 pot ones , how much more progressive are the 8 pots over the 6's given discs sizes .
 
having thought about overnight, probably worth going the whole mile and going 8 pots with larger discs may actually solve some of the caliper /rim contact issues.
