Product Details and Specifications

This disc brake rotor is designed for Chevrolet Corvette vehicles requiring a 5-lug mounting pattern with a 4.750-inch bolt circle diameter. The vented rotor construction with straight vanes helps reduce brake fade by allowing air to flow through the rotor during operation. The smooth surface finish ensures proper pad contact and braking efficiency. With a nominal thickness of 0.787 inches and a discard thickness of 0.724 inches, this rotor provides a clear service life indicator for replacement. The overall height of 2.512 inches and center hole diameter of 2.780 inches ensure proper fitment and alignment on the hub assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking performance due to rotor thickness below discard limits
• Resolving noise issues related to uneven rotor surfaces
• Improving heat dissipation to prevent brake fade during extended use
• Ensuring proper fitment for Chevrolet Corvette brake systems with 5-lug wheels

Installation Notes and Tips

Before installation, verify rotor dimensions against vehicle specifications to ensure compatibility. Clean the rotor surface to remove any protective coatings or contaminants. Use proper torque specifications for lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, ensure those components are inspected and replaced separately if necessary. It is recommended to replace brake pads simultaneously for optimal braking performance.
