Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.22011R) is designed specifically for Land Rover Discovery, LR4, Range Rover, and Range Rover Sport vehicles. The rotor features a vented construction with pillar-style vanes that promote consistent airflow to reduce heat buildup during braking. The cross-drilled and slotted surface enhances pad bite and helps evacuate gases, dust, and water, improving overall braking response and reducing fade under demanding conditions.

The rotor’s hat is coated to protect against corrosion, which is critical for maintaining performance and longevity in various driving environments. With a floating disc mounting design, this rotor accommodates thermal expansion, reducing the risk of warping and ensuring consistent contact with brake pads. The rotor measures 360 mm in outside diameter and has a nominal thickness of 30 mm, with a discard thickness of 27 mm, providing clear service limits for maintenance.
