• Rust-resistant Geomet coating to prevent corrosion and extend rotor life
• Solid rotor design with an 11-inch (280 mm) outside diameter
• Nominal thickness of 0.39 inches (10.00 mm) with discard thickness at 0.33 inches (8.40 mm)
• Overall height of 3.00 inches (75.00 mm) and 5 lug holes with 120 mm bolt circle diameter

Detailed Product Description

This Power Stop rear rotor is specifically designed for the BMW Z4, ensuring precise fitment and optimal braking performance. The rotor is made from high carbon cast iron, which improves thermal conductivity and reduces the risk of warping under heavy braking conditions. The Geomet coating provides a protective layer that resists rust and corrosion, helping maintain rotor integrity over time. Featuring a solid rotor design, it offers consistent braking without the complexity of vented rotors, suitable for standard rear brake applications.

The rotor’s dimensions include an 11-inch outside diameter and a 3.00-inch overall height, matching OEM specifications for the BMW Z4. The mounting bolt hole circle diameter is 120 mm with 5 lug holes, ensuring compatibility with the vehicle’s rear brake assembly. The nominal thickness of 0.39 inches allows for a durable rotor surface, while the discard thickness of 0.33 inches indicates when replacement is necessary to maintain safe braking performance.

About the Power Stop - Rear Genuine Geomet High Carbon Coated Rotor Line
