Installation Notes and Tips

Verify rotor diameter, vented-or-solid configuration, and wheel/brake package details before installation. This Bosch QuietCast Rotor 25011438 is listed for rear position only, so confirm the vehicle’s rear brake specification against the fitment notes for Cadillac CT5, Chevrolet Camaro, Chevrolet Impala, Buick LaCrosse, Buick Regal, Chevrolet Malibu, and related applications.
