Dynamic Friction Company Disc Brake Rotor P/N:604-31130

Give your rear brakes a precision-machined, coated replacement with the Dynamic Friction brake rotor 604-31130, the blank version of DFC's GEOSPEC coated rotor. It fits many vehicles, among them the 2020-2026 Toyota GR Supra, 2017-2022 BMW 740i xDrive and 2022-2026 BMW 230i, as a direct-fit rear replacement. See the Buyer's Guide tab for the full list and engine details.

As a disc brake rotor, it is the spinning surface the pads clamp against to slow the wheel. Its vanes help carry away the heat that braking creates.

• Precision machining: CNC-machined to the tightest tolerances, then 100% precision cut and mill-balanced for smoother stopping and reduced vibration.
• OE vane configuration: the vane configuration is designed to provide proper heat dissipation.
• Iron castings: made from premium G3000/G11H18 iron castings for strength, stability and durability.
• GEOSPEC coating and finish: the coating provides superior corrosion protection over zinc or conventional painting. A non-directional finish helps the rotor break in faster and stop more smoothly.

The rotor is designed to meet the same form, fit and function as OEM brake rotors and is quality tested. It arrives ready to install, with no additional pre-degreasing needed, which saves time during the job. Replacing both rear rotors together as a matched pair is recommended for even, balanced braking.
