I know this will have been covered before but all the posts on the forum i’ve seen don’t give the clearest answer. I’m looking to swap my front discs to 310mm off the mk1 audi tt 1.8t as they bolt straight on. Do i need new brake calipers and brackets & hangers or just the discs?

Wait for someone more knowledgeable but calipers and carriers and disks. There is a sticky on this forum by Ross I think.
