: StopTech Sport pads are for drivers who brake late, smooth, and hard. They require a little bit of heat, but not as much as full track/race pads, to work properly. Once at operating temperature they are quiet and stop better than any OEM pad out there. Brake dust is moderate and well below OEM BMW brake padsAbout StopTech Slotted Rotors
: StopTech slotted high-carbon brake rotors feature grooves in the rotor friction surface to evacuate gases, water, and dust from between the brake pad and rotor. StopTech applies a black e-coating on the hats, edges, and vanes to prevent corrosion and improve appearance.
These StopTech rotors are single-piece cast iron rotors. The factory BMW rotor is a 2-piece iron disc with an aluminum hub. BMW advertised the lighter weight as a way of lowering emissions and improving fuel economy. There is likely no performance difference between them but the Zimmermann will be slightly heavier compared to stock. We also offer the Original BMW rotors if you wish to keep the lighter two-piece design.
