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

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors designed to improve braking efficiency and thermal management. The cross-drilled surface pattern helps to dissipate heat and gases generated during braking, while the vented design with pillar-style vanes promotes airflow to maintain rotor temperature. This product line is suitable for drivers seeking enhanced brake response and durability on Land Rover models such as the Discovery, LR4, Range Rover, and Range Rover Sport.

Technical Specifications and Features

These rotors feature a vented construction with pillar-style vanes that optimize cooling under demanding conditions. The coated hat finish provides protection against corrosion, extending rotor life. The floating disc mounting allows for slight movement to accommodate thermal expansion, reducing the risk of warping. The rotor measures 14.173 inches (360 mm) in outside diameter with a nominal thickness of 1.181 inches (30 mm) and a discard thickness of 1.063 inches (27 mm). The center hole diameter is 3.110 inches (79 mm), and the mounting bolt hole circle diameter is 4.724 inches (120 mm) with five lug holes sized at 0.591 inches (15 mm).

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance for Land Rover Discovery, LR4, Range Rover, and Range Rover Sport
• Addresses corrosion issues with coated hat finish
• Compatible with factory 5-lug wheel configurations

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.063 inches) before installation
• Verify compatibility with vehicle’s ABS system; this rotor does not include an ABS tone ring
• Use proper torque specifications for mounting bolts on the 5-lug pattern
• Inspect hub and mounting surfaces for cleanliness and damage prior to installation
• Recommended to replace brake pads when installing new rotors for optimal performance
