• Fitment issues when replacing BMW 135i or BMW 135is rotors

Installation Notes and Tips

Verify the vehicle’s model year and brake configuration before ordering. This rotor set is listed for front and rear positions, but the fitment notes differ between the BMW 135i and BMW 135is, so match the application exactly to the vehicle. Confirm rotor style and axle position during brake inspection before installation.
