[s-cars] RE: S4 TT Brakes on a urS6

1) bolt spacing is off. Which isn't insurmountable in and of itself,
however...

2) in order to get the bleeders right side up you would need to swap
sides. Due to trailing vs. leading edge mount you would end up with the
piston bores staggered incorrectly which would hugely accelerate tapered
pad wear.

Not to mention that these calipers are HEAVY.
