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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to improve braking efficiency by enhancing heat dissipation and reducing brake fade. The cross-drilled holes and slots help evacuate gases and debris from the rotor surface, which is critical during aggressive driving or repeated braking. This product line focuses on solid rotors with a coated hat finish to provide corrosion resistance and maintain structural integrity over time.

Technical Specifications and Features

This rotor features a solid design with a 10.189-inch outside diameter and a nominal thickness of 0.394 inches, ensuring compatibility with Mini Cooper brake systems. The floating disc mounting style allows for slight movement to reduce stress and improve rotor lifespan. The rotor includes four stud/lug holes with a 0.638-inch diameter and a mounting bolt hole circle diameter of 3.937 inches (100 mm). The center hole diameter measures 2.524 inches (64.1 mm), and the rotor weighs approximately 7.7 lbs (3.5 kg). The surface type is slotted and drilled, which aids in heat dissipation and brake pad cleaning.

Applications and Problem Solving

• Reduces brake fade during high-performance or repeated braking
• Improves heat dissipation to maintain consistent braking
• Helps prevent glazing and buildup on brake pads
• Provides corrosion resistance with coated hat finish
• Compatible with Mini Cooper vehicles requiring part number 127.34094L

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.331 inches) before installation
• Verify compatibility with Mini Cooper brake system and mounting specifications
• Use proper torque settings on lug nuts and mounting bolts
• Inspect brake pads and hardware during rotor replacement
• Clean rotor surface before installation to remove any protective coatings
