18Z 6 pot calipers with 350 mm discs

[aledenro0803]

Hi, I am new here. I recently bought an A3 8l and I wanted to improve my brakes. I saw in some posts the it’a necessary an adapter to be able to fit those massive brakes. Any chance someone knows where can I buy those adapters? Or if someone can give me the required length between bolt holes, so I can pay someone to fabricate them. Thanks!!

Z18's with R32 334mm discs will work just as well for most people..
All other discs are mostly 5x112, and need to be redrilled to 5x100

Thanks for the help, right now my car has 18 inch wheels. The brakes should fit, I gues haha

I just received my R32 334mm discs, I'm hoping to run them with Porsche Macan 4-piston calipers, hope to trial-fit them this weekend.

Test-fitted them yesterday..
No luck, these calipers have a different offset then the Brembo Z18's unfortunately. So with the 'standard' Z18 bracket adapters, these will not fit(the calipers sits WAY further towards the disc then the Z18 caliper does, by at least 5mm) so I would either need to remake the adapters, or just ditch the whole idea of using these Macan calipers and go for the Z18's instead...
