• Compatible with Acura RL rear disc brake systems
• Vented rotor design for improved heat dissipation
• Rust resistant Geomet coating to prevent corrosion
• Nominal thickness of 16.00 mm with a discard thickness of 14.00 mm
• Overall diameter of 309.50 mm (12.20 inches) and height of 67.00 mm (2.60 inches)
• Five lug holes with a 120.00 mm bolt circle diameter

Detailed Rotor Specifications and Features

This Power Stop rear rotor features a vented design that enhances cooling during braking, reducing the risk of brake fade under demanding conditions. The rotor’s Geomet coating provides a protective layer against rust and corrosion, extending the rotor’s service life especially in environments prone to moisture exposure. With a nominal thickness of 16.00 mm and a discard thickness of 14.00 mm, the rotor maintains structural integrity and safety margins for wear. The 309.50 mm outside diameter and 67.00 mm overall height ensure proper fitment and compatibility with the Acura RL rear brake assembly. The five lug holes and 120.00 mm bolt circle diameter match factory specifications for secure mounting.

About the Power Stop - Rear Genuine Geomet Coated Rotor Line
