Designed for smooth, steady stops, the Dynamic Friction brake rotor 600-31170D is a new-in-box rear left rotor that is precision mill-balanced and CNC-machined. It fits many vehicles, among them the 2020-2026 Toyota GR Supra, 2021-2022 BMW iX3 and 2022-2026 BMW 230i. See the "Vehicles it fits" section for the full list and engine details.
- Balanced and machined: 100% precision mill-balanced to help deliver smoother stopping and minimize vibration, and CNC-machined to tight tolerances.
- Premium iron castings: Engineered with G3000/G11H18 iron castings for strength, stability and durability.
- OE vane configuration: Uses an original equipment vane layout designed for proper heat dissipation.
- Non-directional finish: Promotes faster break-in and smoother stops.
Built to match the form, fit and function of OEM brake rotors, this disc brake rotor arrives new in box and ready to install, with no modifications required. Each rotor is quality tested. It is sold individually for the rear left position, and we recommend replacing both rear rotors together as a matched pair for even, balanced braking.
A rotor may need replacing if you notice any of these signs: a pulsating brake pedal, vibration when braking, deep grooves or scoring on the braking surface, or grinding noises. Diagnose the cause before replacing parts.
