Rotor GM Metric 79 & Up

The Rotor GM Metric 79 & Up from AFCO Racing Products is a premium brake rotor engineered for General Motors vehicles with metric brake systems manufactured from 1979 onward. Whether you're rebuilding a classic muscle car's braking system, upgrading a street rod, or restoring original stopping power to a vintage GM platform, this rotor delivers the thermal management and fade resistance that serious enthusiasts demand. Designed to meet OEM specifications while supporting both stock and modified brake setups, this component is essential for anyone committed to reliable, predictable braking performance.

AFCO's rotor construction utilizes high-carbon cast iron material that resists warping under sustained braking loads and thermal cycling—critical factors in both daily driving and performance applications. The metric specifications ensure precise fitment to GM's post-1979 brake hardware, eliminating clearance issues that plague mismatched components. Weighing 17.73 lbs per rotor, this is a quality, substantial piece built to dissipate heat efficiently and maintain consistent friction coefficients across a wide temperature range. The rotor's design accommodates both OEM and aftermarket brake pads, giving you flexibility in your brake system configuration without compromising safety or longevity.

Mechanics and enthusiasts restoring or upgrading GM vehicles from 1979 forward will appreciate AFCO's attention to fitment accuracy and manufacturing consistency. Installation is straightforward on any GM metric brake platform; the rotor bolts directly to the hub using stock mounting hardware. Whether paired with classic drum-brake conversions, power brake upgrades, or high-performance disc brake kits, this rotor provides the thermal stability and durability needed for confidence on the street or strip. For anyone serious about brake system integrity on vintage or modified GM iron, the Rotor GM Metric 79 & Up is a proven, no-compromise choice.
