Fitment and Application Details

Use BR901038 when servicing the rear brake system on BMW Z4 models listed above. This rotor measures 2.95 in. / 75 mm at the center hole diameter and 2.95 in. / 75 mm overall height, with a 0.57 in. / 14.6 mm mounting bolt hole diameter. It is a solid, non-slotted, non-cross-drilled rotor with no ABS tone ring included.

What This Rotor Helps Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface irregularity
• Reduced braking performance from rotors at or near discard thickness
• Service issues on BMW Z4 rear brake maintenance jobs
• Replacement needs for drum-in-hat rear rotor applications

Installation Notes and Tips

Confirm rotor dimensions, bolt pattern, and rear fitment before installation. The 2006 BMW Z4 listing applies to vehicles built to 1/06, so verify build date before ordering. Inspect pads, caliper condition, and hub mating surfaces during brake service to help ensure proper rotor seating and even braking contact.
