About the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering rotors that combine cross-drilled holes and precision slots to enhance braking efficiency. This design helps maintain consistent brake pad contact, reduces gas buildup, and improves water dispersion. The rotors feature a vented construction with pillar-style vanes to optimize airflow and cooling, making them suitable for sporty driving conditions and daily use on vehicles such as the Audi S3 and Volkswagen Golf R.

Detailed Product Description

These disc brake rotors feature a 340 mm outside diameter and a nominal thickness of 30 mm, with a discard thickness of 27 mm, ensuring long service life before replacement is necessary. The vented rotor design incorporates pillar-style vanes that promote effective heat dissipation, reducing the risk of brake fade during extended use. The cross-drilled and slotted surface improves pad bite and helps clear brake dust and gases, contributing to consistent braking performance. The coated hat finish protects against corrosion, maintaining rotor integrity over time. The floating disc mounting system allows for slight rotor movement, which helps prevent warping and uneven wear. This rotor is designed for vehicles with a 5-lug wheel pattern and a center hole diameter of 65 mm, making it compatible with a range of Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pad bite with slotted and drilled design
• Minimizes corrosion with coated hat finish
• Maintains consistent braking performance in wet conditions by dispersing water

Installation Notes and Tips

• Ensure compatibility with your vehicle’s make and model before installation
• Check rotor thickness and discard limits to confirm replacement timing
• Use proper torque specifications for mounting bolts to avoid rotor damage
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Bleed brake system after installation to maintain brake responsiveness
