• Vented rotor design with straight vane style to reduce brake fade
• Coated hat finish for corrosion resistance and durability
• Overall diameter of 305 mm (12.008 inches) and nominal thickness of 20 mm (0.787 inches)
• Five lug holes with a 120.7 mm (4.752 inches) bolt circle diameter
• Compatible with Jaguar Vanden Plas, XJ6, XJ8, XJ12, XJR, XJS, XK8, and XKR models

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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves cooling and helps evacuate gases and debris from the rotor surface, which is critical for maintaining consistent brake pad contact. The vented rotor construction with straight vanes further aids in heat dissipation, making these rotors suitable for both street and light performance driving applications on Jaguar vehicles.

Technical Specifications and Features

These rotors feature a nominal thickness of 20 mm (0.787 inches) and a discard thickness of 18.5 mm (0.728 inches), ensuring a long service life before replacement is necessary. The overall height measures 67.9 mm (2.673 inches), and the center hole diameter is 73.8 mm (2.906 inches). The rotors are designed with five lug holes, each 13.3 mm (0.524 inches) in diameter, arranged on a 120.7 mm (4.752 inches) bolt circle diameter. The coated hat finish provides corrosion resistance, extending rotor life in various driving conditions. Weighing approximately 7.15 kg (15.72 lbs), these rotors balance durability with manageable weight for optimal vehicle dynamics.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking by improving heat dissipation
• Minimizes brake dust and debris buildup on rotor surface for consistent braking performance
• Helps prevent glazing and uneven pad wear through slotted and drilled design
• Improves braking response and pad bite on Jaguar Vanden Plas, XJ6, XJ8, XJ12, XJR, XJS, XK8, and XKR models
• Addresses rotor corrosion issues with coated hat finish for longer service life

Installation Notes and Tips

• Ensure rotor discard thickness of 18.5 mm is not exceeded before replacement
• Verify compatibility with vehicle lug pattern: 5 lug holes on 120.7 mm bolt circle diameter
• Clean rotor surface before installation to remove any protective coatings or residues
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check brake pads for wear and replace if necessary to maximize rotor performance
