Overview

This Dynamic Friction disc brake rotor is a fitment-specific replacement for the front left position on select Acura NSX models. It combines a vented rotor design with a slotted and drilled surface to support consistent brake response under demanding street use.

Part number 830-58004L is part of the DFC Geoperformance Rotor line, which focuses on performance-oriented rotor construction with a corrosion-resistant finish package.

Key Features

  • Fits 1991-1996 Acura NSX, front left.
  • Vented rotor construction for improved heat management.
  • Slotted and drilled braking surface for more aggressive pad contact.
  • Geospec Silver Grey hat finish with rust-resistant coating.
  • 5-lug pattern with 114.3 mm bolt circle and 70 mm center hole.
  • Part number 830-58004L for accurate ordering and catalog matching.

Detailed Description

The Dynamic Friction 830-58004L is a vented disc brake rotor engineered for the front left side of the Acura NSX from 1991 through 1996. Its directional, slotted X drilled surface is built for drivers who want a rotor with a more performance-focused braking profile, while the plain disc finish and corrosion-resistant coating help maintain a cleaner appearance over time. The rotor measures 282 mm outside diameter, 36 mm overall height, and 28 mm nominal thickness, with a 26 mm discard thickness specification.

As part of the DFC Geoperformance Rotor - Drilled and Slotted line, this rotor emphasizes a performance rotor design with a coated hat and rust-resistant surface treatment. If you are replacing a worn front brake rotor on an Acura NSX, part number 830-58004L provides the fitment and dimensions needed for a direct application match.

What It Helps Address

  • Brake pulsation caused by a worn or uneven rotor surface.
  • Reduced braking consistency from heat buildup in the rotor.
  • Surface corrosion on an exposed brake rotor.
  • Noise or pad feel changes associated with rotor wear.
  • Fitment issues when replacing the correct front left rotor on an Acura NSX.

Installation Notes

Verify rotor dimensions, bolt pattern, and center bore before installation. This rotor uses a 5-lug, 114.3 mm bolt circle with 12.5 mm bolt and stud/lug hole diameters. Confirm the front left position and compare the removed part to part number 830-58004L before installation.

Quality Assurance

Dynamic Friction’s Geoperformance Rotor line is built around performance-focused rotor construction and corrosion-resistant finishing. Part number 830-58004L is cataloged for the specified Acura NSX fitment and dimensional requirements.
