Keep rear braking smooth and true with the DYNAMIC FRICTION brake rotor 604-31060 (also written 60431060), a GEOSPEC coated rear rotor that drops in as a direct-fit replacement for the 2003-2006 BMW Z4. It is designed to meet the same form, fit, and function as OEM brake rotors.
This is a rear-axle rotor sold individually — this listing is for one. For even, balanced braking, replacing both sides together as a matched pair is recommended. See the Buyer's Guide tab for engine-level fitment on the 2003-2006 BMW Z4.

This is a rear-axle rotor. The catalog lists it for the rear position on the 2003-2006 BMW Z4.
What is this rotor made of?
It is engineered with premium G3000/G11H18 iron castings for strength, stability, and durability, and is CNC-machined to tight tolerances.
Do I need to replace both sides at once?
