Dynamite Friction 830-59045L Disc Brake Rotor - Front Left

Drilled and Slotted Front Left Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted, part number 830-59045L, is a vented disc brake rotor built for the front left position. It features a 300 mm outside diameter, 25 mm nominal thickness, and a 23 mm discard thickness for applications that require precise brake service dimensions.

Compatible with select Acura ILX, Honda Civic, Acura CSX, Acura RSX, and Honda CR-V front left brake applications, this rotor uses a directional slotted and drilled surface to support consistent pad contact and heat management. The Geospec Silver Grey hat finish and rust resistant coating add corrosion protection, while the plain disc finish keeps the braking surface focused on function.

Product Details

The DFC Geoperformance Rotor line focuses on brake rotors with drilled and slotted surfaces for drivers who need a direct-fit replacement with defined service dimensions. This rotor is engineered for front left use on 2002-2006 Acura RSX, 2006-2015 Honda Civic, 2007-2010 Acura CSX, 2013-2015 Acura ILX, and 2005-2006 Honda CR-V applications. The part number 830-59045L should be matched to the vehicle’s rotor size, bolt pattern, and position before installation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from heat buildup in repeated stops
• Corrosion on the rotor hat and non-friction surfaces
• Rotor replacement needs for front left service on listed vehicles
• Fitment issues when the vehicle requires a 5-lug, 114.3 mm bolt circle rotor

Installation Notes

Verify rotor diameter, center hole diameter, bolt circle diameter, and thickness before installation. This rotor is directional, so confirm the rotation orientation during mounting on the front left side. Inspect pads, caliper condition, and hub surface before installing part number 830-59045L to help ensure proper brake contact and even wear.

Quality Assurance

The Geospec Silver Grey hat finish and rust resistant coating provide added protection on non-friction surfaces. As a vented, drilled, and slotted rotor from Dynamite Friction, this component is built to meet the dimensional requirements listed for the confirmed Acura and Honda applications.
