Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (part number 127.22010L) is specifically designed for Land Rover vehicles including the LR3, LR4, and Range Rover Sport. The rotor measures 350 mm in outside diameter and has a nominal thickness of 20 mm, with a discard thickness of 17 mm, ensuring it meets OEM specifications for safe and reliable braking. The vented rotor features straight vanes that promote airflow to reduce heat buildup during heavy braking conditions.

The rotor surface is cross-drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, improving pad bite and reducing brake fade. The coated hat finish protects against rust and corrosion, maintaining the rotor’s structural integrity over time. The floating disc mounting system allows for slight movement between the rotor and the hub, accommodating thermal expansion and reducing the risk of warping.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for sport and off-road applications.
