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 management and pad cleaning. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing gases and dust to escape, while the vented rotor design with curved vanes promotes efficient airflow. This product line is suitable for performance-oriented vehicles like the BMW M3, where consistent braking under demanding conditions is essential.

Technical Specifications and Features

This disc brake rotor features a vented design with curved vanes that optimize cooling during heavy braking. The rotor's outside diameter measures 325 mm (12.795 inches), with a nominal thickness of 28.000 mm (1.102 inches) and a discard thickness of 26.400 mm (1.039 inches), ensuring durability and longevity. The hat section is coated to resist corrosion, maintaining rotor integrity over time. The rotor mounts using a floating disc design and includes five lug holes with a diameter of 14.8 mm on a 120 mm bolt circle diameter, specifically engineered for BMW M3 fitment.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves heat dissipation to prevent rotor warping
• Enhances brake pad cleaning to maintain consistent friction
• Minimizes brake dust buildup for cleaner braking surfaces
• Provides reliable stopping power for BMW M3 vehicles

Installation Notes and Tips

When installing the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.34059R) on a BMW M3, ensure the rotor surface is clean and free of any protective coatings before mounting. Use proper torque specifications for the 5 lug bolts on the 120 mm bolt circle diameter. Verify that the rotor thickness is above the discard thickness of 26.400 mm to maintain safety and performance. It is recommended to replace brake pads simultaneously to optimize braking efficiency.
