Dynamic Friction 604-31208 Disc Brake Rotor - Rear

Product Overview

The Dynamic Friction 604-31208 is a rear disc brake rotor built for BMW and Mini applications that require a vented, smooth-surface replacement rotor. It uses a non-directional brake surface for consistent serviceability and a plain disc finish for a clean OE-style appearance.

Compatible With BMW and Mini rear brake applications, this rotor is specified for select 2024-2026 BMW X1, 2024-2026 BMW X2, 2025-2026 BMW M235 xDrive Gran Coupe, and 2025 Mini Cooper Countryman fitments. The 604-31208 part number is also useful when matching the correct rear rotor by size and hub dimensions.

Key Features

• Vented rotor design for improved heat management during braking.
• Non-directional braking surface for flexible installation and service.
• Plain disc finish with a smooth surface type.
• 5-bolt pattern with 112 mm bolt circle diameter.
• 330 mm outside diameter, 51 mm height, and 67 mm center hole diameter.
• Dynamic Friction DFC GEOSPEC Coated Rotor line.

Detailed Description

The Dynamic Friction 604-31208 disc brake rotor is engineered as a rear replacement rotor for select BMW and Mini vehicles. Its vented construction supports heat dissipation, while the smooth, non-directional braking surface helps maintain even contact characteristics during service. The DFC GEOSPEC Coated Rotor line identifies this rotor as part of Dynamic Friction's coated rotor family, which is aimed at clean appearance and practical corrosion resistance in everyday brake service.

Use the 604-31208 when you need a rear rotor that matches the listed fitments and dimensional requirements. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn rear brake rotor with the correct vented design.
• Restoring braking performance when rotor thickness is below service limits.
• Addressing brake pulsation caused by rotor wear or surface irregularity.
• Correcting noise or vibration related to rotor condition.

Installation Notes and Tips

Verify rear fitment by year, model, and brake package before ordering. Confirm the 330 mm outside diameter, 112 mm bolt circle diameter, 5-bolt pattern, and 67 mm center hole diameter against the existing rotor. The 604-31208 is listed for rear applications only, so position matching is important on BMW X1, BMW X2, BMW M235 xDrive Gran Coupe, and Mini Cooper Countryman vehicles.

Quality Assurance

Dynamic Friction identifies this rotor as part of the DFC GEOSPEC Coated Rotor line, which is built around coated rotor construction for service-focused brake replacement.
