Technical Specifications and Features

The 981063R rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. Its nominal thickness of 1.102 inches (28.000 mm) ensures sufficient material for longevity, while the discard thickness of 1.024 inches (26.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 1.858 inches (47.200 mm) and outside diameter of 12.598 inches (320.000 mm) are engineered to fit precisely on compatible Acura models. The five mounting bolt holes with a 4.496 inch (114.200 mm) bolt circle diameter and 0.496 inch (12.600 mm) bolt hole diameter provide secure attachment to the wheel hub. The smooth surface type promotes even brake pad wear and consistent braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on Acura MDX and TLX
• Addresses brake noise caused by uneven rotor surfaces
• Helps restore braking efficiency lost due to rotor thickness below specifications
• Reduces vibration during braking from rotor runout or damage
• Improves heat management to prevent brake fade in daily driving

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 1.102 inches (28.000 mm). Clean the rotor surface and hub mounting area to remove rust or debris for proper fitment. Use the correct torque specifications on the five mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Verify compatibility with Acura MDX and TLX models before installation.
