Dynamic Friction Company Disc Brake Rotor P/N:900-63165

Bring your rear brakes back to a smooth, true stop with the Dynamic Friction brake rotor 900-63165. This rear disc brake rotor drops in as a direct-fit replacement for the 2015 Mercedes-Benz S400, 2017 Mercedes-Benz S550, 2018-2020 Mercedes-Benz S450, and 2018-2021 Mercedes-Benz S560.

• Precision mill-balanced: 100% mill-balanced to help promote smoother stops and reduce vibration.
• Premium iron castings: engineered with G3000/G11H18 iron castings for strength, stability, and durability.
• Geomet® coated: Geomet coating provides high-performance corrosion protection.
• OE vane configuration: original-equipment (OE) vane configuration to support proper heat dissipation.

A fine-turned finish (16 RMS) aids initial rotor and pad break-in, while tight tolerances — disc thickness variation held to a 0.010 mm maximum and lateral runout to a 0.050 mm maximum — keep the disc running true. Cast from high-carbon alloy, this rotor is sold individually; for even, balanced braking, replace both rear rotors together as a matched pair.
