Description

Bring smooth, balanced braking back to the rear axle with the Dynamic Friction brake rotor 604-31109 (also written 60431109), a GEOSPEC-coated blank rotor engineered to meet the same form, fit, and function as the OEM rear rotor. It drops in as a direct-fit replacement across a wide range of BMW models, including the 2017-2020 BMW 430i, the 2014-2016 BMW 328i and the 2012-2015 BMW 335i — see the "Vehicles it fits" section for the full list of applications.

Precision machined: CNC-machined to tight tolerances and 100% precision cut and mill-balanced for smoother stopping and reduced vibration.
OE vane configuration: matches the original-equipment vane configuration to promote proper heat dissipation.
GEOSPEC coating: provides corrosion protection over zinc and conventional painting.
Non-directional finish: helps promote faster pad break-in and smoother stops.

Cast from premium G3000/G11H18 iron castings for strength and stability, this blank (non-drilled, non-slotted) rotor arrives ready to install with no additional pre-degreasing preparation needed. Sold individually — for even, balanced braking it is best practice to replace the rotors on both sides of the axle together as a matched pair.
