What It Helps Address

• Rear brake pulsation caused by worn rotor surfaces
• Corrosion on the hat and outer edge of the rotor
• Brake noise related to uneven rotor wear
• Reduced braking consistency from rotor thickness loss
• Service replacement needs on Porsche 924, 928, and 944 rear brakes

Installation Notes and Tips

Confirm rotor dimensions, hub fitment, and chassis breakpoints before installation, especially on the 1986 Porsche 928 application. Inspect pads, calipers, and wheel bearings during brake service, and clean the hub mounting surface so the rotor seats evenly. Verify the 5-lug bolt pattern and center hole diameter match the vehicle before assembly.

Quality Assurance

Centric Premium rotors use a resin-modified protective coating on the hat and edge for corrosion resistance, with salt chamber testing cited at 120 hours. Part number 120.37007 is built to the listed specifications for the confirmed Porsche rear applications above.
