BRAKE DISC

Keep braking quiet and controlled with the HELLA Brakes Disc Brake Rotor 355119531. It drops in as a front, internally-vented direct-fit replacement for the 2011-2017 BMW X3 [All] and 2015-2018 BMW X4 [All], and is built to meet OEM standards (ECE R90 ready).

• High-carbon gray cast iron, full-cast: the high carbon content helps heat dissipation, while the casting material dampens noise and vibration and resists deformation.
• Full zinc coating: applied to the coated disc and hat surfaces for corrosion resistance.
• Fixing screws included: the mounting screws come in the box to simplify installation.
• Non-oiled surface: no degreasing needed before install.
• Key specs: 328 mm outside diameter, 28.0 mm nominal thickness, 26.4 mm discard/minimum thickness, smooth non-directional surface, and 5 bolt holes on a 120 mm bolt circle.

This rotor is internally vented for cooling. It does not include an ABS tone ring, wheel hub, wheel studs, or wheel bearings — transfer or replace those as directed by the service procedure. For even, balanced braking, replacing both front rotors as a matched pair is recommended; this listing is for one rotor (order 2 for a complete front-axle replacement). Country of origin: China. Manufacturer part number 355119531.
