The A3 does dive like a bitch under heavy braking but that is due to it's massive front bias and ****ty back brakes. The fronts are C25 calipers and discs and the rears are escort Mk3 drums. The handbrake works (if that is a word I can use) off the rear drums. As for handling , it's astonishing once you get use to the roll. I took class wins in a number of european endurance events (sub 2.0lltr diesel NA) where due to the lack of power speed was maintained by getting round corners quick. Once you fit a decent turbo lump in them the A3 is a hoot on the road and you can use that rear wheel drive and LSD to its maximum advantage - hell even the NAD is damned quick. It's all about weight balance, springing, shocks, wheelbase and CoG
