Mine is a 2003 2.0T (B207R) and it is equipped with 314mm front discs.
So not only the B284 have 314mm discs but the early Aero's as well.

Is there any braking performance benefit to having 314mm front discs rather than 302mm? i.e. would they be a better choice on a remapped car?

Yes, the larger diameter alone gives an improved stopping power. The pads also have a greater area. Together they are a very worthwhile upgrade.

Great - my discs will need doing at some point in the next year or so, so that might be the time to upgrade ;)

Need to source callipers off a scrap early Aero first though ;)

The same calipers were also fitted to the 3.2 Vectras  ;). Make sure you get the carriers too.

My 2005 Saab 9-3 Arc Convertible has no brake codes... Shows the first numbers, but the brake codes are blank, with dashes.... What so I do?
