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 pad cleaning. The combination of cross-drilled holes and precision slots helps reduce brake fade during aggressive driving conditions, making them suitable for performance-oriented Audi S4 drivers. The vented rotor design further aids in cooling, while the coated hat finish protects against corrosion, extending rotor life.

Technical Specifications and Features

This disc brake rotor features a vented construction with straight vane style to optimize airflow and heat management. The rotor’s overall height measures 47.3 mm (1.862 inches), and it includes a floating disc mounting system to accommodate thermal expansion and reduce the risk of warping. The rotor does not include ABS tone rings or bearings, so these components must be sourced separately if required. The center hole diameter is 68 mm (2.677 inches), and the rotor mounts with five lug holes sized at 15 mm (0.591 inches) diameter on a 112 mm bolt circle.

Applications and Problem Solving

• Improves braking performance for Audi S4 models under high-stress conditions
• Reduces brake fade caused by excessive heat buildup
• Helps prevent rotor warping and uneven pad wear
• Enhances pad cleaning to maintain consistent braking response
• Protects against corrosion with coated hat finish for longer service life

Installation Notes and Tips

• Ensure compatibility with Audi S4 model year and specifications before installation
• Check rotor thickness and discard limits to confirm suitability for replacement
• Use proper torque specifications for the 5 lug bolts on the 112 mm bolt circle
• Inspect brake pads and related hardware during rotor replacement
• Verify absence of ABS tone ring compatibility if your vehicle requires one
