I've read the definitive brake guide in the stickies, but it doesn't mention if there is any difference in brake size for the pre-facelift (210 bhp) S3. As no one has mentioned it, I'm assuming the front discs for a pre-facelift are 312mm (the same as the 225 bhp version).
I've just rang GSF Car Parts for a price though, giving the guy my car registration, and he quoted me a price for 288mm discs. I asked if that was the correct size, as I thought it was 312mm and he said he was pretty sure they are 288mm.
So basically, before ordering I would like to know the correct size for the front disc brakes on an 2000 plate pre-facelift S3 Quattro (210 bhp).
