Technical Specifications and Features

The 981823R rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. Its nominal thickness of 0.866 inches (22.000 mm) ensures sufficient material for wear, while the discard thickness of 0.787 inches (20.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 1.795 inches (45.600 mm) and outside diameter of 11.575 inches (294.000 mm) are engineered to fit precisely on compatible Mini models. The five mounting bolt holes with a diameter of 0.650 inches (16.500 mm) and a bolt circle diameter of 4.409 inches (112.000 mm) provide secure attachment to the wheel hub. The smooth surface type promotes even brake pad contact, contributing to consistent braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mini Cooper and Cooper Clubman
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores braking efficiency when rotor thickness falls below safe limits
• Improves heat dissipation to reduce brake fade during extended use
• Eliminates noise and vibration related to damaged or uneven rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor misalignment
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to maintain optimal braking
• Perform a test drive to verify proper brake function after installation
