My A3 1.8T came with crappy 288mm discs. Probably fine for 150bhp running to Tesco and back but not what is needed when running higher boost and and a new agile suspension setup. The upgrade options for 288mm discs are limited plus no matter what you do you'll still have small discs.
I happened upon a chap who was selling full 312mm front brake setups from brand new TT225's (same setup as the S3). For £250 he supplied brand new Pads, Discs, Calipers, Hoses and Caliper carriers. These were taken from TT's that had spec'd brake upgrades so were genuine parts that hadn't been used - the discs still had their protective oil coating!
Now the calipers on my A3 are the same as the TT/S3, but they were 88k old so i thought no harm in changing them. In order to do the conversion i would only have needed the caliper carriers and discs, but buying these new from Audi would cost as much as this kit so i changed the lot.

After:
As you can see the new discs fill the wheels nicely
As well as changing these parts I used Motul RBF 600 Dot4 Fluid. This is a fantastic fluid with better thermal properties than many Dot5.1 fluids.
The result is better pedal feel and a much improved response from the brakes themselves. Unfortunatley the single piston calipers are still susceptible to fade but as i'm not going anywhere near a race-track i am more than pleased in the improvement in stopping power from the bigger discs!
