Quick facts

Part: Dynamic Friction 900-31171 front brake rotor
Also called: disc brake rotor
Fits: 2022-2026 BMW 230i and other vehicles
Position: Front
Condition: New

Pedal pulsation, a shake through the steering wheel when braking, visible grooves or cracks, or a measured thickness at or below the discard thickness can mean a disc brake rotor needs replacing. A sticking caliper, worn pads or a worn wheel bearing can be behind these signs too, so find the cause before buying.

Fits

This front brake rotor fits the 2022-2026 BMW 230i, the 2023-2026 BMW 230i xDrive and the 2023-2026 BMW 430i Gran Coupe, among other models. If your car is not named, look up its year and model in the Vehicles it fits section. This listing is one rotor; the car takes one on each side of the front axle, and the other side is normally done at the same time.
