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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide improved braking performance through enhanced rotor cooling and pad bite. The cross-drilled holes and precision slots help evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent pedal feel. The vented rotor design further aids in heat dissipation, making this product line suitable for both street and light performance driving applications.

Technical Specifications and Features

This disc brake rotor is vented with straight vanes to optimize airflow and cooling. The rotor’s coated hat finish offers protection against corrosion, extending the rotor’s service life. With a nominal thickness of 18.0 mm and a discard thickness of 16.0 mm, the rotor maintains structural integrity and safety throughout its lifespan. The 5-lug hole pattern with a 149.6 mm bolt circle diameter ensures proper fitment on compatible Lexus Land Cruiser and Toyota LX470 models. The rotor does not include ABS tone rings or bearings, so these components must be reused or replaced separately if needed.

Applications and Problem Solving

• Improves braking performance for Lexus Land Cruiser and Toyota LX470 vehicles
• Reduces brake fade during extended or heavy braking
• Enhances heat dissipation to prevent rotor warping
• Helps maintain consistent brake pedal feel under various driving conditions
• Resists corrosion with coated hat finish for longer service life

Installation Notes and Tips

Ensure compatibility with your Lexus Land Cruiser or Toyota LX470 by verifying the part number 127.44087L and rotor specifications before installation. The rotor is designed for floating/dih disc mounting and requires proper torque on lug nuts to avoid warping. Since bearings and ABS tone rings are not included, inspect and replace these components as necessary during installation. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

StopTech disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The coated finish and vented design contribute to durability and consistent performance. Warranty information is provided by the manufacturer and should be confirmed at the time of purchase.
