You're not going to end up with a generic stage 1 car, given all the things you're asking and the things you are doing. So why do you want to spend good money on a set of discs which will only ever be ''barely'' able to stop the car in anger.
Even if a set of ATE discs and pads were only £150, it's still half the cost of a set of proper brakes.

a set of 312 on a fwd A3 is going to be alot better than a set on an S3
I would be buying plain discs from ecp or something, its pads and fluid that matters
