BMW is not talking wheel diameter in a recent press release, they are talking rotor diameter for their new line ofperformance brake kits for the 2015 X6 M. Let me put this into perspective, the Bugatti Veyron only has 15.7″ rotors in the front and the Ferrari 458 only has 15.4″ rotors. The BMW Power Kit also comes with larger 18-inch front brake discs, with a retrofit kit to increase the diameter to a whooping 19″.
Larger, inner-vented 19-inch BMW M Performance lightweight brake discs increase the heat resistance and therefore the effectiveness of the brakes under extreme conditions. The blue painted brake calipers, with imprinted BMW M logo at the front, are showcased particularly effectively by open wheel rim designs.
BMW is offering the brake package with the factory warranty that probably does not cover wear on the pads of rotors. They have not indicated if the kits are carbon-ceramic or cast, in the pictures it looks like it could go either way. If the 19 rotor is cast iron, it should weigh as much as a manhole cover.
