Harold maybe you know the answer to this,...I understand that some people only do the front BBK and leave the stock calipers. Would this upset the natural brake bias that BMW has engineered? I would think so. If that is the case is it possible to use the FRONT calipers in the rear with the 345mm BBK rotor size? Since the front is 345mm and the BBK rears are 345mm why couldnt I upgrade just the front calipers until I am ready to do the rears? This way I use the front stock calipers AND rotors as the rear set until I am ready to shell out another $2000 or so on the rear set. Is this doable? Thanks.
Do you mean upgrading the front to a proper BBK and leave the rear as is? This has been done many times and will not upset the balance of the car at all. Stoptech BBK engineers their BBK so the user can upgrade the fronts only.

Please PM me your current set-up so I can help you further.
