• Front position disc brake rotor for BMW fitments
• Drilled dimples with ventilated construction
• High-carbon machining for thermal stability
• Coated surface for improved corrosion resistance
• 6/5 hole arrangement, 120 mm bolt hole circle, 79 mm hub bore
• Weight: 10.9 kg

Detailed Description

Zimmermann manufactures this rotor as an equivalent-quality replacement part built to the dimensions and material quality specified by the vehicle manufacturer. The coated surface helps maintain a cleaner appearance and adds protection against corrosion, while the drilled-dimple design supports brake bite and heat management in demanding street use. This rotor cross-references Brembo 09.C398.13 for the same application. The part number 150.2906.20 is also referenced against several OE-style alternatives in the same fitment group.

Compatible BMW applications include front brake setups on the 2012-2020 BMW 230i, 330i, 430i, 440i, M240i, M140i, 328i, 335i, 340i, 428i, 435i, and related xDrive and Gran Coupe models where the listed brake package and rotor size match. For BMW 230i, BMW 430i, and BMW M240i front brake service, verify the brake package notes before ordering.

What This Rotor Helps Address

• Front brake vibration or pulsation from worn rotors
• Reduced braking consistency from heat-affected rotor surfaces
• Corrosion on exposed rotor hats and braking surfaces
• Brake noise or uneven pad contact caused by rotor wear
• Service replacement needs for BMW M Sport and sports package brake systems

Installation Notes and Tips

Confirm rotor diameter, thickness, hub bore, and bolt pattern against the existing brake setup before installation. This rotor is listed for front axle use only and is tied to specific BMW brake packages, including M Sport brake and sports package applications. Always inspect pads, calipers, and hub surfaces during brake service, and replace any worn components that could affect rotor performance. Match the vehicle notes carefully on BMW 230i, BMW 430i, and BMW 440i applications to ensure the correct brake package is selected.

Quality Assurance

Zimmermann standard brake rotors are produced as OE-equivalent replacement parts in line with European motor vehicle block exemption requirements and are manufactured to the dimensions and material quality specified by the vehicle maker. Since 2008, Zimmermann has also offered coated rotors under its Coat Z anti-corrosion finish for improved surface protection.
