Dynamic Friction 810-31134D Disc Brake Rotor - Front Left

Overview

The Dynamic Friction 810-31134D is a slotted disc brake rotor built for BMW and Toyota applications that require a front left replacement rotor with a vented design. It combines a directional braking surface with a rust-resistant coating and Geospec Silver Grey hat finish for a clean, service-ready appearance.

Compatible With BMW 230i, 330i, 430i, M340i, X3, X5, and related models, this rotor is also listed for Toyota GR Supra applications. The 810-31134D is a fitment-specific rotor, so matching the exact vehicle, year, and brake configuration is important.

Key Features

• Slotted braking surface for consistent pad contact and surface cleaning.
• Vented rotor construction for improved heat management.
• Directional brake surface for application-specific rotation.
• Rust-resistant coating helps protect exposed surfaces.
• Geospec Silver Grey hat finish for a finished OE-style appearance.
• Outside diameter: 348 mm; discard thickness: 34.4 mm.

Detailed Description

Dynamic Friction 810-31134D is part of the DFC Geoperformance Rotor - Slotted line, a product line focused on slotted rotor design and corrosion protection. This rotor is engineered for front left fitment on a wide range of BMW performance and luxury models, including BMW 330i, BMW 430i, BMW M340i, BMW X3, and BMW X5 applications, as well as select Toyota GR Supra configurations. The slotted, vented, directional design supports stable braking characteristics and helps maintain a cleaner rotor surface during repeated stops.

Use the 810-31134D when replacing a worn or damaged front left disc brake rotor on vehicles listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation caused by rotor wear or uneven surfaces.
• Reduced braking consistency from a worn rotor face.
• Corrosion on exposed rotor surfaces.
• Heat buildup during repeated braking events.
• Noise or vibration related to rotor condition.

Installation Notes

Install only on the listed front left applications and verify brake package details, including full cast disc or aluminum hat disc notes where shown. Some fitments include configuration-specific notes such as optional full cast disc, 345 mm rear disc, 330 mm rear disc, or Motorsport Engineering Package exclusions. Confirm the vehicle’s brake setup before ordering.

Quality Assurance

Dynamic Friction’s Geoperformance Rotor line emphasizes slotted rotor construction, corrosion protection, and application-specific fitment for BMW and Toyota brake systems. The 810-31134D is built to match the listed vehicle configurations and brake dimensions.
