Dynamic Friction 830-31050R Disc Brake Rotor - Rear Right

Overview

The Dynamic Friction 830-31050R is a rear right disc brake rotor built for BMW performance applications that call for a vented, directional braking surface. It features a slotted and drilled design, rust-resistant coating, and Geospec Silver Grey hat finish for a clean, corrosion-conscious setup.

Fits 2006 BMW M3, rear right, except Competition Package. Fits 2001-2005 BMW M3, rear right. Fits 2000-2003 BMW M5, rear right.

Key Features

• Slotted X drilled surface for consistent rotor cleaning and heat management.
• Vented rotor construction for improved airflow through the disc.
• Rust-resistant coating helps protect exposed surfaces.
• Directional braking surface for application-specific fitment.
• Geospec Silver Grey hat finish for a refined installed appearance.

Detailed Description

This Dynamic Friction disc brake rotor, part number 830-31050R, is engineered for the rear right position on select BMW M3 and BMW M5 models. The rotor uses a 327 mm outside diameter, 20 mm nominal thickness, and a vented design with a directional slotted-and-drilled braking surface. The 5-lug pattern, 120 mm bolt circle, and 75 mm center hole align with the listed applications, while the rust-resistant coating adds protection against surface corrosion.

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on rotor design details that matter in braking service, including venting, surface pattern, and finish. For buyers searching for a BMW M3 rear right brake rotor or a BMW M5 rear right disc brake rotor, 830-31050R provides a direct fit for the vehicles and notes listed above.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation related to worn or uneven rotor surfaces.
• Reduced braking consistency from heat buildup in the rotor.
• Surface corrosion on exposed brake components.
• Fitment issues when replacing the rear right rotor on listed BMW applications.

Installation Notes

Verify rotor dimensions, bolt pattern, and the rear right position before installation. Confirm the 2006 BMW M3 exception for Competition Package vehicles, since that application is excluded from the fitment list. Match the rotor to the listed vented, directional configuration and inspect related brake components during service.

Quality Assurance

Dynamic Friction’s Geoperformance rotor line is built around application-specific rotor construction and finish details for service replacement use. Part number 830-31050R is listed with confirmed fitment for the BMW M3 and BMW M5 applications shown above.
