With 27 covered vehicles, see the Buyer's Guide tab for the full list and engine coverage.

  • Geomet® coated: provides high-performance corrosion protection.
  • Premium G3000/G11H18 iron castings: built for strength, stability, and durability.
  • 100% precision mill-balanced: for smoother stops.
  • Fine-turned finish (16 RMS): helps improve initial rotor and pad break-in.
  • OE vane configuration: designed to support proper heat dissipation.

This high-carbon alloy rotor is machined to tight tolerances, with a Disc Thickness Variation (DTV) of 0.010 mm maximum and lateral runout of 0.050 mm maximum for consistent pedal feel. It installs as a rear replacement on the listed Audi, Volkswagen, and Cupra applications. This listing is for one rotor, sold individually; for even, balanced braking, replacing both rear rotors as a matched pair is recommended.
