With a 5-bolt mounting pattern and a bolt circle diameter of 4.528 inches (115.000 mm), this rotor ensures secure fitment. The nominal thickness of 1.270 inches (32.250 mm) provides a solid braking surface, while the discard thickness of 1.209 inches (30.700 mm) indicates the minimum safe thickness before replacement is necessary. The overall height and center hole diameter are engineered to match factory specifications for proper installation and performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on compatible Buick, Chevrolet, Pontiac, and Saturn vehicles
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Improves braking consistency and heat management during heavy-duty or frequent braking
• Restores proper rotor thickness to maintain safe braking distances
• Compatible with vehicles experiencing rotor-related brake pulsation or reduced stopping power

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern against vehicle specifications before installation
• Ensure mounting surfaces are clean and free of debris to prevent rotor misalignment
• Torque mounting bolts to manufacturer-recommended specifications for secure fitment
• Inspect brake pads and hardware during rotor replacement for optimal system performance
• Check rotor thickness regularly to avoid discarding below the minimum thickness of 1.209 inches
