EBC Ultimax Slotted Brake Rotors are designed to provide the braking benefits of slotted rotors with quieter operation. The progressively angled slots help reduce the air noise commonly associated with slotted designs while improving brake performance during everyday driving and demanding conditions. As part of the EBC Ultimax OE Style Disc Set, the RK903 rear rotors are engineered for a precise fit on select BMW 323i and 323Ci applications.
The angled slots help draw cool air across the braking surface, supporting lower operating temperatures and consistent brake response. They also help remove excess brake dust, debris, and gases from between the rotor and pad, helping maintain strong pad contact and reliable grip. By supporting cleaner pad contact and improved heat management, these rotors can also contribute to longer pad service life.
Designed for the rear axle, the EBC RK903 rotor set features a vented construction, five-bolt mounting pattern, and compatibility with FMSI pad number D692. These rotors are intended as an OE-style replacement upgrade for drivers seeking dependable fitment, quiet slotted performance, and consistent braking characteristics. Verify vehicle application and brake configuration before installation to ensure compatibility with your specific BMW.
