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 rotor cooling and debris removal. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing heat and gases to escape more efficiently. This product line is ideal for drivers seeking reliable, consistent braking on Jaguar models that demand both performance and durability.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes that promote airflow to reduce heat buildup during braking. The rotor’s coated hat finish offers corrosion resistance, helping maintain structural integrity over time. With a floating disc mounting system, the rotor accommodates thermal expansion, reducing the risk of warping. The rotor measures 326 mm in outside diameter and 19.9 mm in nominal thickness, meeting OEM specifications for Jaguar vehicles listed.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pedal feel on Jaguar S-Type and XJ models
• Minimizes brake dust and debris buildup for cleaner braking surfaces
• Provides corrosion resistance for longer rotor lifespan

Installation Notes and Tips

• Ensure compatibility with Jaguar models: S-Type, Super V8, Vanden Plas, XF, XJ, XJ8, XJR, XK, and XKR
• Check rotor thickness before installation; discard thickness is 18.0 mm (0.709 inches)
• Use proper torque specifications for the 5 lug bolts on the 108 mm bolt circle diameter
• Inspect brake pads and calipers for wear during rotor replacement
• Follow manufacturer guidelines for bedding-in new rotors to optimize performance
