About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance for sport and luxury vehicles. The cross-drilled surface improves water and gas evacuation from the rotor surface, reducing brake fade under demanding conditions. The vented design helps maintain consistent rotor temperatures, which is critical for vehicles like the Jaguar F-Type and XKR that require reliable stopping power during spirited driving. The coated hat finish offers protection against corrosion, extending the rotor's lifespan.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves wet weather braking performance by dispersing water
• Minimizes rotor warping through efficient heat dissipation
• Restores braking efficiency on Jaguar F-Type, S-Type, XF, and other compatible models
• Addresses uneven brake pad wear due to rotor surface imperfections

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.181 inches) before installation
• Use proper torque specifications for the 5-lug mounting pattern (bolt circle diameter 4.252 inches)
• Inspect brake pads and calipers for wear when replacing rotors
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check for compatibility with vehicle ABS systems as this rotor does not include an ABS tone ring
