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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to provide enhanced braking performance through improved heat dissipation and debris evacuation. The combination of cross-drilled holes and precision slots helps reduce brake fade and maintain consistent pedal feel during spirited driving or track use. This product line focuses on delivering reliable stopping power while maintaining durability and corrosion resistance, making it suitable for performance-oriented Audi S4 drivers.

Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes that promote airflow between the rotor faces, effectively reducing heat buildup during braking. The rotor surface is cross-drilled and slotted to help evacuate gases, dust, and water, which can otherwise reduce braking efficiency. The coated hat finish protects the rotor from rust and corrosion, extending its service life. The floating disc mounting system allows for slight movement between the rotor and hub, which helps prevent warping and ensures even pad contact. With an outside diameter of 300 mm and a nominal thickness of 22 mm, this rotor meets the precise fitment requirements for the Audi S4. The 5-lug hole pattern with a 112 mm bolt circle diameter and 15 mm lug hole diameter ensures proper mounting compatibility.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance in wet or dusty conditions
• Minimizes brake dust buildup on rotor surface
• Prevents premature rotor corrosion with coated hat finish

Installation Notes and Tips

• Ensure compatibility with Audi S4 before installation
• Inspect brake pads and calipers for wear during rotor replacement
• Follow manufacturer torque specifications for lug nuts (5 lug holes, 15 mm diameter)
• Check rotor thickness regularly; discard thickness is 20.0 mm
• Properly bed new rotors and pads to optimize braking performance
