Detailed Fitment and Performance

StopTech 127.62127R is engineered for rear right applications on a wide range of GM and Cadillac platforms, including Cadillac CT5, Cadillac CT6, Cadillac XTS, Chevrolet Camaro, Chevrolet Impala, Buick Regal, Buick LaCrosse, Chevrolet Malibu, Chevrolet Malibu Limited, Saab 9-5, and Buick Allure. It is a strong match for shoppers searching for a rear right drilled and slotted brake rotor for Cadillac CT5, rear right brake rotor for Chevrolet Camaro, or a vented rear disc rotor for Buick LaCrosse and Regal applications.

The cross-drilled and slotted surface helps move heat and brake dust away from the pad face, reduces glazing, and improves wet and dry braking consistency. The coated hat and black e-coating also help the rotor maintain a cleaner appearance and resist corrosion in everyday use. Part number 127.62127R is sized at 315 mm outside diameter with a floating disc mounting design, straight vane construction, and a 67.4 mm center hole diameter.

What This Rotor Helps Address

• Brake fade during repeated stops
• Pad glazing that can reduce initial bite
• Brake dust buildup on the rotor surface
• Corrosion on exposed rotor areas
• Uneven braking feel on worn factory-style rotors
