• Coated hat finish to resist corrosion and extend rotor life
• Compatible with 5-lug wheel setups and 12mm stud thread diameter
• Nominal thickness of 1.035 inches (26.3 mm) with discard thickness at 0.965 inches (24.5 mm)
• Overall diameter of 10.504 inches (266.8 mm) and height of 4.323 inches (109.8 mm)

Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved rotor cooling and pad bite. The cross-drilled holes and precision-machined slots help evacuate gases and debris from the braking surface, reducing the risk of brake fade during demanding driving conditions. This rotor line is vented with straight vanes to optimize airflow and maintain consistent rotor temperatures, making it suitable for vehicles like the Chevrolet Camaro, Pontiac Firebird, and Buick Regal.

Technical Specifications and Compatibility

This disc brake rotor features a vented design with straight vanes, which improves heat dissipation compared to solid rotors. The coated hat finish protects against rust and corrosion, ensuring durability over time. It is designed for vehicles with a 5-lug wheel pattern and a mounting bolt hole circle diameter of 120.7 mm (4.752 inches). The rotor’s center hole diameter measures 70.5 mm (2.776 inches), and it does not include an ABS tone ring or bearings.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup during aggressive driving
• Improves braking response and pad bite with slotted and drilled surface
• Helps prevent rotor warping and cracking under high thermal stress
• Minimizes corrosion on the rotor hat area with a protective coating
• Compatible with popular GM models such as Chevrolet Malibu, GMC Jimmy, and Oldsmobile Cutlass Supreme

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.965 inches) before installation
• Use proper torque specifications for 12 mm stud threads and 1.5 mm bolt thread pitch
• Inspect wheel bearings and seals (Inner Bearing #410.91006, Outer Bearing #410.910034) during rotor replacement
• Clean rotor surface before installation to remove any protective coatings or debris
• Check compatibility with vehicle ABS systems as this rotor does not include an ABS tone ring
