Get smoother, vibration-free rear-axle braking with the Dynamic Friction brake rotor (P/N 604-31117 / 60431117), a GEOSPEC-coated blank rotor engineered as a rear-axle replacement for a long list of BMW cars. It drops in on models including the 2007-2013 and 2015-2016 BMW 328I, the 2011-2015 BMW X1, the 2016-2020 BMW 420I, and the 2017-2020 BMW 430I — see the Buyer's Guide tab for all 22 applications.
DFC precision-cuts and mill-balances every rotor for smoother stopping with minimal vibration at any speed, and casts it from premium G3000/G11H18 iron for strength and stability.
- CNC-machined to tight tolerances: 100% precision cut and mill-balanced for smooth, quiet braking.
- OE vane configuration: matches the original-equipment vane configuration to support proper heat dissipation.
- GEOSPEC coating: provides superior corrosion protection over zinc and conventional painting.
- Ready to install: non-directional finish promotes faster break-in, with no pre-degreasing prep needed.
This is a blank (non-slotted, non-drilled) rear rotor designed to meet the same form, fit, and function as the OEM part. It covers common applications like 2011 Bmw 328I rotors along with many later BMW models. This listing is for one rotor; for even, balanced braking, replace both rear rotors as a matched pair.
