I’m considering big brakes up front. Within BMW CCA rules for Prepared cars, I’m limited to 4 pot calipers. There are several choices that I’ve identified:

- Performance Friction, at Bimmerworld 323 x 32 mm two piece rotors, forged billet two piece calipers, $2,900

- Stoptech, at Bimmerworld — 332 x 32 mm two piece rotors, two piece calipers, $2000 (also sold by Tuner at $200 premium)

- Brembo, at Turner Motorsport — 332 x 32 mm two piece rotors, two piece calipers, $3200

- Alcon at UUC — 325 x 28 mm floating rotors, two piece calipers, $2400

- Wilwood at UUC — 325 mm floating rotors, two piece billet calipers, $1500

- Rotora at evosport — 330 x 30 mm two piece rotors, two piece billet calipers, $1700

The UUC units come with factory floating rotors (from the E46 M3, I think), which are cross drilled by the factory. I won’t run cross drilled rotors, so those are out, unless there’s an aftermarket two-piece rotor that fits the application. The Performance Friction units sure are pretty, but they ain’t cheap. The Brembos also suffer from very high prices. The Rotora look like serious racing equipment (e.g. ceramic pads), are near the low end of the price spectrum, and are supported by a (sort of) local tuner.

No decision yet, but I seem to be leaning Rotora.
