Product Details

ATE, the Continental Automotive Systems brake brand, applies OE-level engineering and manufacturing discipline to aftermarket brake parts. The coated rotor design helps protect the braking surface from corrosion during storage and service, while the vented full cast design supports stable heat management under repeated braking. SP22273 is specified for rear fitment on 2011-2018 Audi A8 Quattro, 2013-2018 Audi S6, 2013-2018 Audi S7, and 2013-2018 or 2016-2018 Audi S8 applications, depending on brake system configuration. This part cross-references Brembo 09.C170.11 and Zimmermann 100.3362.20 for the same application.

What This Rotor Helps Address

• Rear brake pulsation from worn or uneven rotor surfaces
• Corrosion on exposed rotor surfaces
• Brake noise caused by rotor wear or surface irregularity
• Reduced braking consistency from heat-related rotor fatigue
• Service replacement needs on Audi rear brake systems

Installation Notes

Confirm rear axle fitment, rotor diameter, thickness, and bolt pattern before installation. This rotor is not suitable for ceramic composite brakes. Clean the hub mounting surface thoroughly and inspect pads, caliper hardware, and wheel bearings before completing the brake service. For best results, replace rotors in axle pairs and follow the vehicle manufacturer’s torque and bedding procedures.

Quality Assurance

ATE brake parts are produced to a higher standard than conventional aftermarket replacements, using engineering and process controls informed by Continental Automotive Systems’ OE brake system experience. The coated rotor finish and full cast construction reflect ATE’s focus on premium brake components for the aftermarket.
