• Brake pulsation caused by uneven rotor condition
• Noisy braking associated with worn rear rotors
• Fitment issues when replacing BMW M Sport rear rotors with the wrong rotor design

Installation Notes and Tips

Confirm the rear brake package on the vehicle before ordering, since this part is listed for multiple rotor constructions and M Sport brake configurations. Match the vehicle year, model, and rotor style shown in the fitment data for proper application. Part number 4002-31061 should be verified against the existing rear rotor setup before installation.
