StopTech Slotted Sport Rotor Overview

The StopTech Sport Slotted Disc Brake Rotor, part number 126.62117SR, is a direct replacement rotor for factory brake systems and stock calipers. It is built for the rear right position on select 2008-2010 Chevrolet Cobalt applications, including Brembo front caliper setups noted in the fitment data.

With a vented, slotted design and coated hat finish, this rotor is made to support more consistent braking response while helping manage heat and brake dust. The black e-coating adds corrosion protection, and the high-carbon metallurgy used in most applications supports quieter operation and improved crack resistance.
