Why original BMW brake parts?
Over the years we have tried many different variations of brake components on BMWs, and what we have learned is that the original brake rotors and linings perform better for street use than any other combination. The superior cold performance and lack of any noise or vibration makes them ideal for daily driving. The only drawback to original equipment is the dark grey brake dust caused by the high carbon linings. After-market linings can cure the dust problem but quite often create other issues. A shaking steering wheel as you slow from freeway speeds, and even when not braking, can often be cured with BMW brake discs/rotors. As the non-original rotors heat cycle from driving, they often become warped like an lp record. The BMW rotors are cast from very soft and porous steel; they dissipate heat very uniformly, and when the factory linings are used, the pores at the surface of the rotors collect and hold carbon from the linings to help adhesion and minimize vibrations (noise).
