Detailed Product Description

This StopTech Sport Cross-Drilled Disc Brake Rotor (part number 128.34066L) is specifically designed for Mini Cooper vehicles, ensuring precise fit and optimal braking performance. The rotor features a solid construction with a cross-drilled surface type that improves heat dissipation and reduces brake fade during aggressive driving or extended braking periods. The coated hat finish provides enhanced corrosion resistance, extending the rotor's service life. With a nominal thickness of 0.394 inches and a discard thickness of 0.331 inches, this rotor meets strict specifications for safe and effective braking. The rotor's outside diameter measures 10.197 inches, and it has an overall height of 1.732 inches, matching OEM dimensions for direct replacement. The floating disc mounting design allows for slight movement to reduce stress and improve rotor longevity. This rotor does not include ABS tone rings or bearings, so it is intended for vehicles with compatible brake system components.

About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is engineered to provide enhanced braking performance through improved heat management and durability. Cross-drilled rotors like the 128.34066L help dissipate heat more efficiently than standard rotors, reducing the risk of brake fade and maintaining consistent pedal feel. This product line is designed for drivers who require reliable stopping power in both daily driving and spirited conditions, making it a suitable upgrade for Mini Cooper owners seeking a balance of performance and longevity.
