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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through advanced rotor surface technology. The combination of cross-drilled holes and precision slots helps to evacuate heat, brake dust, and gases more efficiently than standard rotors. This product line is ideal for drivers seeking improved brake response and reduced fade under demanding driving conditions, such as spirited street driving or light track use. The vented design with pillar-style vanes further aids in cooling, making these rotors a reliable upgrade for Jaguar performance models.

Technical Specifications and Features

These rotors feature a vented construction with pillar-style vanes that promote airflow and heat dissipation. The floating disc mounting allows for slight movement between the rotor and hat, accommodating thermal expansion and reducing the risk of warping. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. With a center hole diameter of 2.791 inches (70.900 mm) and five lug holes sized at 0.551 inches (14.000 mm), these rotors are designed for precise fitment on specified Jaguar models. The rotor weighs approximately 25.5 lbs (11.59 kgs), balancing durability and performance.

Common Applications and Problem Solving

• Improves brake cooling to reduce fade during aggressive driving
• Helps prevent brake judder caused by uneven rotor surface temperatures
• Reduces buildup of brake dust and gases for consistent pad contact
• Enhances stopping power for Jaguar S-Type, Super V8, Vanden Plas, and XJR vehicles
• Addresses corrosion issues with coated hat finish for longer rotor life

Installation Notes and Tips

• Ensure compatibility with your Jaguar model and verify part number 127.20018R before installation
• Inspect brake pads and replace if worn to maximize rotor performance
• Follow manufacturer torque specifications for lug nuts and mounting bolts
• Check for proper rotor runout and alignment during installation
• Break in new rotors and pads according to recommended procedures to ensure optimal performance
