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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat dissipation and debris removal. The combination of cross-drilled holes and precision slots helps maintain consistent pad contact and reduces brake fade. This product line is suitable for drivers who require reliable stopping power and rotor durability, especially in sporty or spirited driving conditions. The coated hat finish adds corrosion resistance, extending rotor life.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor has a floating disc mounting system that allows for slight movement to reduce stress and improve alignment. The rotor's overall height measures 44.7 mm (1.760 inches), with a center hole diameter of 64.1 mm (2.524 inches) and a mounting bolt hole circle diameter of 100 mm (3.937 inches). It includes four stud/lug holes with a diameter of 16.2 mm (0.638 inches). The rotor surface is slotted and drilled to enhance braking performance by evacuating gases and debris from the pad surface.

Common Applications and Problem Solving

• Improves braking performance for Mini Cooper vehicles under high-stress conditions
• Reduces brake fade caused by excessive heat buildup
• Helps prevent rotor warping and uneven pad wear
• Enhances wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation on the rotor surface

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 if your vehicle requires these components separately. Proper torque specifications should be followed when mounting the rotor using the four stud/lug holes. It is recommended to inspect and replace brake pads simultaneously to ensure optimal performance. The coated hat finish should be handled carefully to avoid damage during installation.
