Dynamic Friction Company Disc Brake Rotor P/N:900-63107

Keep every stop smooth and true with the DYNAMIC FRICTION brake rotor 900-63107, a rear disc brake rotor that installs as a direct-fit replacement for the 2014-2019 Mercedes-Benz CLA250, 2014-2016 Mercedes-Benz GLA200, 2014-2020 Mercedes-Benz GLA250, 2014-2015 Mercedes-Benz B Electric Drive, and 2017-2019 Infiniti QX30. It's 100% precision mill-balanced to help deliver smoother stopping with reduced vibration at speed.

• Premium castings: Cast from G3000/G11H18 high-carbon alloy iron for strength, stability, and durability.
• Geomet® coated: Provides high-performance corrosion protection.
• Fine-turned finish (16 RMS): Helps improve initial rotor and pad break-in.
• OE vane configuration: Designed to promote proper heat dissipation.

Held to tight tolerances — Disc Thickness Variation of .010 mm maximum and lateral runout of .050 mm maximum — for consistent, true rotation. This is a rear-axle rotor sold individually; for even, balanced braking it's best practice to replace both rear rotors together as a matched pair.
