Dynamic Friction Company Disc Brake Rotor P/N:604-31098

Keep the rear brakes on your BMW smooth and true with the Dynamic Friction brake rotor 604-31098 (also written 60431098) — a GEOSPEC-coated rear disc brake rotor engineered to meet the same form, fit, and function as the OEM rotor. It installs as a direct-fit replacement for the 2009-2016 BMW Z4; see the Buyer's Guide tab for engine-level fitment.

• CNC-machined: cut to tight tolerances, then 100% precision-cut and mill-balanced to help smooth stops and reduce vibration.
• OE vane configuration: matches the original vane layout to support proper heat dissipation.
• G3000/G11H18 iron castings: premium castings for strength, stability, and durability.
• GEOSPEC coating: provides corrosion protection beyond zinc and conventional painting.
• Non-directional finish: promotes faster pad break-in and smoother stops, and it arrives ready to install with no pre-degreasing needed.

This is a rear rotor sold individually. For even, balanced braking, it's best practice to replace both rear rotors as a matched pair — order two for a complete rear-axle service. If worn or warped rotors are behind pedal pulsation or a vibration you feel while braking, this direct-fit replacement addresses the rear rotor.
