Product Line Details: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors designed to improve braking efficiency and thermal management. Featuring cross-drilled surfaces and vented construction, these rotors help maintain consistent brake feel and reduce fade during spirited driving or daily use. The coated hat finish enhances durability by protecting against corrosion, making them suitable for Mini Cooper owners seeking a balance of performance and longevity.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and heat dissipation. The cross-drilled surface pattern aids in water and gas evacuation, improving brake pad contact and reducing the risk of brake fade. The rotor has a floating disc mounting system, allowing for controlled thermal expansion and minimizing warping. The coated hat finish provides additional protection against rust and environmental wear. Key dimensions include an outside diameter of 294 mm (11.575 inches), nominal thickness of 21.9 mm (0.862 inches), and an overall height of 44.7 mm (1.760 inches). The rotor includes four stud/lug holes with a diameter of 16.2 mm (0.638 inches) and a mounting bolt hole circle diameter of 100 mm (3.937 inches).

Applications and Problem Solving

• Improves braking performance for Mini Cooper vehicles
• Reduces brake fade during extended or aggressive driving
• Enhances heat dissipation to prevent rotor warping
• Minimizes corrosion with coated hat finish
• Maintains consistent brake pad contact through cross-drilled design

Installation Notes and Tips

Ensure compatibility with your Mini Cooper model before installation. The rotor does not include bearings or an ABS tone ring, so verify existing components for compatibility. Proper torque specifications should be followed when mounting the rotor using the four stud/lug holes. It is recommended to inspect brake pads and hardware during installation to ensure optimal performance. The floating disc mounting requires correct alignment to function as intended.
