S4 B6 345mm brakes on A4 1,8TQ B6 ?

[Magnus_A4TQ]

Hi !
Have some questions about uppgrade my brakes to S4 B6 brakes 345mm.
Have read that S4 B5 321mm brakes fits like a glove on 1,8T B6.

Hope that anyone can answer om my questions.

1. Does the B6 S4 calipers fit right on to my car

2. Do i need adaptor for the calipers ?

3. Do i need to change master cylinder to B6 S4 ? With only front brakes from S4 b6?

4. May i change master cylinder if i change front and rear?

5. How big wheels do i need ? have 18" on summer tires and 16" URS4 5spoke on snow.

Hope you can help me

Best regards
Magnus from Sweden

I have them on my 1.8T quattro.
No additional brackets or parts are needed.
They are completely bolt-on.

Not sure if you'll be able to get them under your 16" wheels though.
They fit fine under both my 18" ASA AR1s (Summer) and my 18" B6 S4 (winter).

They'll fit behind some 17s, the OEM sport wheels being one set that is ok. Otherwise you'll have to stick with 18s.

Thank you for fast and good answers !

I think i have to look for B5 S4 calipers so i can use my 16" S4 winter tyres.
But 345mm brakes on front and 300mm on the back are very nice !
