This product line is designed to meet the demands of performance-oriented vehicles, including the Chevrolet Camaro and Pontiac G8, ensuring reliable braking under aggressive driving conditions.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 1.256 inches (31.9 mm) and a discard thickness of 1.181 inches (30 mm), ensuring a long service life before replacement is necessary. The rotor has an outside diameter of 13.992 inches (355.4 mm) and an overall height of 1.957 inches (49.7 mm). It includes a vented design with pillar-style vanes to enhance airflow and cooling during braking. The rotor’s hat is coated to resist corrosion, and it mounts using a floating disc system to reduce stress and warping. The center hole diameter measures 2.654 inches (67.4 mm), with a mounting bolt hole circle diameter of 120 mm (4.724 inches) and five lug holes sized at 0.638 inches (16.2 mm).

Compatible Vehicles and Applications

• Buick Regal
• Chevrolet Camaro
• Pontiac G8
• Chevrolet SS

These rotors are designed specifically for these models, ensuring proper fitment and optimal braking performance.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup during aggressive driving
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor hats reducing lifespan
• Warping and vibration from thermal stress
• Reduced braking efficiency from gas and debris accumulation

Installation Notes and Tips

Installation requires proper torque specifications for the 5-lug mounting pattern and verification of rotor thickness before mounting. The floating disc design allows for slight movement to reduce stress, so ensure all mounting hardware is secure but not over-tightened. This rotor does not include bearings or an ABS tone ring, so verify compatibility with your vehicle’s braking system. It is recommended to replace brake pads simultaneously to ensure optimal performance.
