New M3/M4 Carbon Ceramic Brakes on 1M?

His view in his application was that the benefit did not warrant the cost. Maybe the BMWs are different but I would do my homework before I go down this path.

The Porsche ceramic rotors are poorly suited to lots of track use because the rotors only have a relatively thin braking surface applied to them which can wear or be damaged easily. Lots of Porsche trackies revert to steel for this reason. The other option is to upgrade to Movit rotors. Would be interesting to know the technology behind the BMW ceramic rotors especially if someone is considering this as a track upgrade.

And sorry to run on, but one clear advantage expressed by some M3 owners that have gone the BBK route is improved modulation over the OEM brakes.

Essentially you'll need to do some repeated stops similar to what you would do when bedding in new pads but less aggressively with less heat buildup. When you bed in pads you're transferring pad material to the rotor. By using a less aggressive procedure you keep the temps down and can remove the transfer material. It may take several "stops" to accomplish this.

A great pad for cleaning rotors are hawk Blues. When cold they are like sandpaper. Just drive around town making normal stops and you will have squeaky clean rotors in no time.
