ATE SP20191 Disc Brake Rotor - Rear

ATE Coated Rear Rotor for BMW X5

The ATE Coated Single Pack Rotor SP20191 is a vented rear disc brake rotor built for 2002-2006 BMW X5 applications. It uses a full cast metal construction, a non-directional finish, and a rust-resistant coating to support consistent braking performance and cleaner service life.

ATE, a Continental Automotive Systems brand, applies OE-level brake engineering to its aftermarket rotor line. The coated rotor design follows that approach with first-quality materials and process control for drivers who need a direct-fit rear brake rotor for BMW X5 service.

Product Details

This ATE coated rotor is engineered for rear brake service on the BMW X5 and is built to meet or exceed OEM specifications for disc brake rotors in North America. The coated surface helps protect non-friction areas from corrosion, while the vented full cast design supports heat management during repeated braking. If you are replacing worn rear rotors on a 2002-2006 BMW X5, SP20191 provides a direct application match with OE-focused dimensions and construction.

This part cross-references Brembo 09.A541.11 for the same application.

What It Helps Address

• Brake pulsation from rotor wear or thickness variation
• Corrosion on the rotor hat and non-friction surfaces
• Reduced braking consistency from heat buildup
• Noise caused by uneven rotor surfaces
• Rear brake service needs on BMW X5 models

Installation Notes

Confirm rotor dimensions, hub fitment, and rear axle application before installation. Clean the hub mounting surface thoroughly, inspect pads and caliper hardware for wear, and follow the vehicle manufacturer’s torque specifications during assembly. After installation, bed in the brake pads according to the pad manufacturer’s procedure to help establish even rotor contact.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ OE brake manufacturing experience and are produced to a higher standard than conventional replacement parts. The SP20191 rotor reflects that OE-focused engineering approach for BMW X5 rear brake service.
