Overview

The Dynamic Friction DFC Geoperformance Rotor is a drilled and slotted disc brake rotor built for specific rear left applications. Part number 830-54037L features a vented design, directional braking surface, and a rust-resistant coating for consistent service in demanding brake systems.

Compatible with Ford Mustang rear left fitments, this rotor is engineered around the listed dimensions and hub pattern for accurate replacement. The 830-54037L is a fitment-specific brake rotor for drivers replacing a worn or heat-affected rear rotor on the Mustang.

Key Features

  • Drilled and slotted surface for improved pad bite and heat management.
  • Vented rotor construction for better airflow through the disc.
  • Rust-resistant coating with Geospec Silver Grey hat finish.
  • Directional brake surface for application-specific braking performance.
  • 5-lug pattern with 114.3 mm bolt circle and 70.8 mm center hole.

Detailed Description

The DFC Geoperformance Rotor line focuses on performance-oriented brake replacement with a drilled and slotted surface profile and corrosion protection on exposed areas. This rotor uses a plain disc finish, vented construction, and a directional braking surface to match the requirements of the listed Ford Mustang rear left applications. Part number 830-54037L is specified for 1994-1999, 2001, and 2003-2004 Ford Mustang rear left fitments, making it a targeted replacement for those vehicles.

For shoppers comparing Ford Mustang brake rotor options, this rotor provides the listed dimensions: 296 mm outside diameter, 51 mm overall height, 18 mm nominal thickness, and 16.8 mm discard thickness. The 830-54037L is also identified by its 5-bolt, 114.3 mm bolt circle layout and 14.5 mm bolt and lug hole diameter.

What It Helps Address

  • Brake pulsation from a worn or uneven rotor surface.
  • Reduced braking consistency caused by heat buildup.
  • Surface corrosion on exposed rotor areas.
  • Loss of pad contact quality on a damaged rear rotor.

Installation Notes

Fits 1994-1999 Ford Mustang, rear left. Fits 2001 Ford Mustang, rear left. Fits 2003-2004 Ford Mustang, rear left. Verify rotor dimensions, bolt pattern, and center hole diameter before installation. Because this rotor is directional, confirm correct orientation during installation on the specified rear left position.

Quality Assurance

Dynamic Friction’s DFC Geoperformance Rotor line combines drilled and slotted construction with a rust-resistant coating for brake service applications that require controlled heat dissipation and corrosion protection. Part number 830-54037L is built to the listed specifications for the confirmed Ford Mustang fitments.
