Product Line Details: Power Stop Rear Drilled, Slotted and Zinc Plated Rotors

The Power Stop - Rear Drilled, Slotted and Zinc Plated Brake Rotor Pair is part of a product line designed to improve heat dissipation and reduce brake fade through its drilled and slotted surface design. The zinc plating provides a protective coating that helps prevent rust and corrosion, extending the rotor’s service life. This rotor set is solid type, offering a balance of strength and performance suitable for rear brake applications on compatible Lexus vehicles.

Technical Description and Specifications

This disc brake rotor set features a solid rotor design with a surface that is both drilled and slotted to enhance braking efficiency by allowing gases and debris to escape during braking. The nominal thickness varies between 10.50 mm and 11.90 mm, with a discard thickness of 10.50 mm, indicating when the rotor should be replaced to maintain safe braking performance. The rotors measure 307.00 mm (12.10 inches) in outside diameter and have an overall height of approximately 63.50 mm (2.50 inches). The mounting bolt hole circle diameter is 144.30 mm, accommodating 5 lug holes with a diameter of 5.70 mm, ensuring proper fitment on the specified Lexus models.
