Bavarian Auto has some overpriced powder coated stock calipers.

Stoptech is an option. You could get 4 calipers for $2,000

or Stoptech's rotor and pad upgrade:

Not sure of the price of the rotor upgrade. The website does not show it and I have not gotten around to giving them a call.

Does anyone on here have any experience with Stoptech?
