Overview

The Dynamic Friction 920-31185D is a drilled disc brake rotor built for BMW applications that require a front-right replacement with a directional brake surface. It features a plain disc finish, a 395 mm outside diameter, and a 34.4 mm discard thickness specification for the listed fitments.

Fits 2020-2026 BMW X5, front right. Fits 2020-2026 BMW X6, front right. Fits 2020-2025 BMW X4, front right. Fits 2020-2024 BMW X3, front right.

Key Features

  • Hi-Carbon Alloy GEOMET coated rotor construction for corrosion resistance.
  • X-drilled surface pattern for improved heat management and brake response.
  • Directional braking surface for correct rotation-specific installation.
  • Plain disc finish with a large 395 mm outside diameter.
  • Part number 920-31185D for fitment verification and ordering.

Product Details

This Dynamic Friction brake rotor is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled line, which focuses on coated rotor construction and drilled surface engineering. The 920-31185D is listed as a full cast replacement for aluminum hat disc applications on BMW X5, BMW X6, BMW X4, and BMW X3 models in the specified front-right position. The directional, X-drilled design supports consistent braking performance while the coated finish helps protect the rotor surface.

This part cross-references no interchange numbers provided for the same application.

Common Issues Addressed

  • Brake rotor wear that requires replacement at the specified discard thickness.
  • Surface corrosion on the braking face.
  • Heat buildup during repeated braking.
  • Rotor replacement needs for directional, drilled-disc applications.

Installation Notes

Verify rotor diameter, discard thickness, and directional orientation before installation. Confirm the front-right fitment and match the vehicle application notes for aluminum hat disc replacement. Use the part number 920-31185D to confirm the correct BMW X5, BMW X6, BMW X4, or BMW X3 application before service.

Quality Assurance

Dynamic Friction identifies this rotor as part of its Hi-Carbon Alloy GEOMET coated drilled rotor line, combining coated surface protection with drilled brake-surface engineering for the listed applications.
