Rear Right Cross-Drilled Rotor (330x20) - F10 528i/535d/535i

Rear Right 330x20mm brake rotor with cross-drill pattern and anti-rust coating for F10 528i/535d/535i.

Cross-drilled rotors are used mostly to enhance the performance aesthetic of your car. Slotted or blank rotors have greater capacity to store heat so we prefer those for track and racing use. Cross-drilled rotors still have their place as a design that looks great with no detrimental effects under normal street use. Many sports car manufacturers still use drilled rotors because of their sporty looks while knowing they don't lose any effectiveness during normal driving. The holes into the vanes do offer an advantage in wet conditions where the water has an easy escape from the rotor surface. StopTech Drilled rotors are made using Centric High Carbon blank rotors. A black electrostatic coating is applied to prevent rust on the brake hat and vanes. The entire rotor is coated, followed by CNC double-disc grinding and drilling of the friction surface and final computer balancing.

Note: this StopTech rotor is a single-piece cast iron rotor. 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 StopTech will be slightly heavier compared to stock.

Price is per rotor. Photo is for reference but is representative of what you will receive.
