Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors (126.62078SR) are precision-engineered replacement rotors designed to meet the braking demands of Chevrolet, Pontiac, and Saturn vehicles including the Aura, Cobalt, G4, G5, G6, HHR, Ion, Malibu, and Pursuit. Featuring a vented rotor design with pillar-style vanes, these rotors promote effective heat dissipation to reduce the risk of brake fade during extended use. The slotted surface enhances pad bite and helps remove debris and gases from the pad surface, maintaining consistent braking performance.

The rotor’s hat is coated to protect against rust and corrosion, which helps maintain structural integrity and appearance over time. With a floating disc mounting system, the rotor can better accommodate thermal expansion, reducing the risk of warping. The rotor measures 296 mm in outside diameter and has a nominal thickness of 26 mm, ensuring compatibility with the specified vehicle models. The five lug holes with a 110 mm bolt circle diameter match factory specifications for a secure fit.
