    I AM PRETTY CERTAIN THAT THE A3 3.2 V6 USES 312 MM, AS THE STANDARD BRAKE 288MM UPGRADE IS TO GET THE CALIPER CARRIERS OFF THE 3.2 WITH 312MM DISCS

    http://www.vwspares.co.uk/a32.php

    I THINK ITS THE S3 THAT USES THE 345MM

    sorry bout the capitals, only just looked at typing and realised i accidently hit the caps!!!!

    I think frenchy is right at 345mm.

    The Golf 4-motion uses 312mm so would have thought they would have been bigger.

    Also the Mk5 R32 uses bigger than the 4-mo...

    the r32 brakes are bigger, i emailed a bloke from awsome gti and asked about the r32 brakes and he said as they are 345 they will not fit under 17 inch, but the 3.2 v6 rides on 17 inch alloys! im pretty certain that it is 312mm have a lok on that site, it shows all the discs being 280 288 n the s3 is 345 n there is one 312mm disc

    No just 335mm on the Passat - I guess that was big in 2002 when they came up with the stupid car.

    Unfortunately they're unique to this model - different to any other VAG fitment, so no pattern discs available, so VW have the market to W8 discs to themselves!

    Checking out the exhaust thread now.
