You need the carriers off a Audi 2.5 or 3ltr

I tried carriers from a S3/TT and they locating bolts were closer so didn't fit.

I managed to find a set of 312mm calipers/carriers on ebay from a 2004 2.5 B6 and all is good.

New from dealer its over £100 per carrier i think!

could you tell me if it is worth the effort ie does the braking improve enough to justify the outlay

When I bought my car the brakes were shot, trully. So I never had a base line on what the OE brakes were like. The 312s have been on for about 500 miles and there bedding in still I think, but there pretty good. I've heard others say there not that much difference but then other VAG cars its quite evident gains.

They sure look better though, and I'm not lacking any confidence so its all good from me. However with the car being remaped I would be tempted to go for an S4 setup should they come up (I missed a set recently

)

Cheers.
