Product Description

The EBC RK903 rear brake rotor set is engineered as a direct OE-quality replacement for select BMW E36 and early E46 models. Designed to restore factory braking performance, these rotors deliver smooth, consistent stopping power while improving durability over standard OEM-style discs.

Manufactured from high-carbon G3000 cast iron, the RK903 rotors are built to resist heat distortion, brake fade, and vibration under repeated braking conditions. The vented internal structure improves airflow and heat dissipation, helping maintain stable braking performance during daily driving and highway use.

Finished with a Geomet anti-corrosion coating, these rotors resist rust formation and maintain long-term surface integrity. They are designed for direct bolt-on installation with OEM brake components, making them ideal for restoration or maintenance of BMW E36/E46 braking systems.
