With a 5-bolt hole pattern and a center hole diameter of 2.657 inches (67.5 mm), this rotor is engineered for precise fitment on compatible vehicles.

Compatible Vehicles and Applications

• Buick Caprice
• Cadillac CTS and XTS
• Chevrolet Corvette and Regal

This rotor is designed specifically for these models, ensuring proper fit and reliable braking performance when replacing worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Corrosion and rust buildup on rotor hats
• Overheating from insufficient heat dissipation
• Noise and vibration from uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.063 inches (27 mm) before installation. Clean the hub surface and mounting area to prevent runout. Use proper torque specifications on the 5 lug bolts to avoid rotor distortion. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s braking system. The floating disc mounting design requires careful alignment during installation to maintain optimal rotor performance.
