That is what you need, search 312 brakes on ebay for the carriers if you want them brand new, or try and find a used set of Audi S3, 225TT and some higher powered B5 Passat/Audi A4's should do the trick, then 312 brake disks for S3/TT225/Leon Cupra(not R), and any pads that fit the caliper(must be 'Lucas' calipers I think?).
The first upgrade to do on your tqs! standards are so rubbish its unreal, i just got carriers, black diamond vented discs and ferado pads. your suspose to get ds200 pads from farado but i accidently got the crapper ones!.
