Installation Notes and Tips

Compatible With rear axle service on 2008-2013 BMW 135i and 2013 BMW 135is. Verify rotor design and rear brake configuration before installation, since the fitment notes reference multiple rotor setups for these vehicles. Clean the hub mounting surface, inspect calipers and slides, and follow proper bedding procedures after installation to help the pads and rotors seat evenly.
