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 consistent pad contact. The combination of cross-drilled holes and precision slots helps to evacuate gases, dust, and water from the rotor surface, which is critical for maintaining braking efficiency during spirited driving or heavy use. This product line is well-suited for Audi models requiring reliable, vented rotors with a coated hat finish to resist corrosion.

Technical Specifications and Features

These rotors feature a vented design with straight vanes that promote airflow to reduce heat buildup during braking. The coated hat finish protects the rotor’s central mounting area from rust and corrosion, ensuring durability. The floating disc mounting system with a vented hat improves thermal management and rotor longevity. The rotor’s dimensions include a nominal thickness of 0.980 inches (24.9 mm) and a discard thickness of 0.906 inches (23.0 mm), with an outside diameter of 12.283 inches (312 mm) and an overall height of 1.823 inches (46.3 mm). The rotor is designed with five lug holes on a 4.409 inch (112 mm) bolt circle diameter, compatible with the specified Audi models.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive driving
• Improves braking response and pad bite through enhanced surface design
• Minimizes rotor warping by promoting consistent cooling
• Helps prevent corrosion on the rotor hat area with coated finish
• Maintains braking performance in wet or dusty conditions by evacuating debris

Installation Notes and Tips

• Ensure compatibility with Audi A4, A4 Quattro, A6, A6 Quattro, A8, and A8 Quattro models before installation
• Check rotor thickness and discard thickness to confirm replacement necessity
• Use proper torque specifications for the five lug nuts on the 112 mm bolt circle
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
