DISC BRAKE ROTOR

Designed for smooth, quiet stops, the HELLA BRAKES Rear Disc Brake Rotor 355123152 is built to minimize noise and vibration. It drops in as a direct-fit replacement for the rear axle on many BMW 3- and 4-Series applications, including the 2013-2018 320i xDrive, 2014-2018 328d xDrive, 2013-2016 328i xDrive, 2016-2018 330e, 2017-2019 330i xDrive, 2014-2016 428i and 2017-2020 430i Gran Coupe (engine: All) — see the Buyer's Guide tab for the full list of 17 fitments.

• Internally vented, full-cast gray cast iron: the vented core and high carbon content help dissipate heat during braking.
• Full zinc coating: coated disc and hat surfaces help resist rust, built to HELLA Pagid OEM standards and ECE R90 ready.
• Quiet, stable operation: high carbon content and 'soft' casting material help absorb sound and resist deformation.
• Fast install: a fixing screw is included and the non-oiled surface needs no degreasing before fitting.

Specs: 300 mm (11.81 in) outside diameter, 20 mm nominal thickness with an 18.4 mm minimum discard thickness, 6 bolt holes on a 120 mm bolt circle, non-directional smooth face, mill-balanced. Sold individually (package quantity 1); each rear axle uses two, so order 2 and replace both sides together as a matched pair for balanced braking. Does not include wheel studs, wheel hub, bearings, or an ABS tone ring. Country of origin: China. Manufacturer part number 355123152.
