Technical Details and Specifications

This vented disc brake rotor features a smooth surface type that supports consistent pad contact and braking efficiency. The rotor’s nominal thickness is 1.181 inches (30.000 mm), with a discard thickness of 1.102 inches (28.000 mm), indicating when replacement is necessary to maintain safe braking. The overall height of 2.236 inches (56.800 mm) and outside diameter of 13.780 inches (350.000 mm) align with OEM dimensions for proper fitment. The rotor mounts using a floating disc style with a 5-lug hole pattern, each hole measuring 0.492 inches (12.500 mm) in diameter, and a mounting bolt hole circle diameter of 4.5 inches (114.300 mm). The rotor includes 93 pillar-style vanes to optimize airflow and heat dissipation during braking.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Genesis G70 and Kia Stinger
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness for consistent braking performance
• Compatible upgrade for maintaining OEM braking standards

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness specification of 1.102 inches (28.000 mm) to maintain safety. Use proper torque specifications for the 5 lug nuts to avoid rotor warping. This rotor does not include bearings or an ABS tone ring, so confirm compatibility with your vehicle’s existing components. Floating disc mounting requires correct alignment to prevent uneven wear.
