Audi puts on decent size brakes. same for A5/S5? I was suprised by the braking of the A5 on the track (and its handling over the B8 A4), but I really wasn't able to really bury them to the floor since we had to stay in a train.

The B8 gets some trick rotors with like 244 pillars which are individual parallelograms rather than 30-40 continuous or staggered segmented radial vanes. Air does not directly radiate from the center of these pillar type rotors, it must follow a curved path in one of two directions. Also you will notice the the B8 rotors have their vane entrances on the hub side... not the wheel side.

as an option.

B7 A4 also uses the same caliper as the B6/7 S4 which uses 345x30mm rotors

too pretty to get brake dust on, VERY VERY NICE and personalized to boot

You would still need a pair of taller hubs, new front bearings, calipers, brackets and rotors. Some of those components can be had 2nd hand (calipers and hubs) Bearings are ~$30 each new. I won't say this is an inexpensive setup, far from it but what matters most is that it fits my unique needs and that is why I spent so many hours working on it.

A side effect of this setup is gaining 12mm front track width. Extra front track may help handling behavior a tiny bit but it can also cause rubbing depending on what your ride height is set at. I need to review some info but there may be other more powerful (larger pistons) calipers which are compatible with this bracket.

If all goes well I'll be working these brakes over on a number of road courses this year. I have high expectations which I hope can be met by these components.

If you'd use the typical aftermarket wheels that are 35, then you're going to be out to +23 which is going to rub. unless you pull the fenders out for that ghetto widebody.
