Ringbrothers Reveal 1969 Ford Mustang Kingpin Restomod with Modern Engineering at SEMA 2025

Ringbrothers Presents Heavily Modified 1969 Mustang at SEMA 2025 Las Vegas Event

Wisconsin-based custom vehicle manufacturer Ringbrothers displayed a comprehensively rebuilt 1969 Ford Mustang at the 2025 SEMA Show in Las Vegas, which commenced November 4. The vehicle, designated the Kingpin, represents an extensive restomod project that integrates contemporary performance technology with the original Mustang platform.

Construction Timeline and Structural Modifications

The Kingpin project accumulated more than 5,500 production hours from conception to completion. During the rebuild process, Ringbrothers substantially altered the vehicle’s original dimensions and architecture. The body structure received widening across both axles—a 2-inch expansion at the front end and 3.5-inch expansion at the rear. The wheelbase was repositioned 1.5 inches forward relative to the original placement.

The frame system originated from a Roadster Shop Fast Track Stage III platform and was extensively reworked into a unibody configuration. This structural overhaul required replacement of the vast majority of factory Ford components, with minimal original equipment retained in the final build.

Powertrain and Performance Specifications

The engine assembly comprises a Wegner Motorsports 5.0-liter Coyote V-8 unit, augmented with a Whipple supercharger for increased output. Transmission duty falls to a Bowler Transmissions six-speed manual gearbox. Ringbrothers documents a total engine output figure of 800 horsepower.

Stopping capability comes through Brembo brake system hardware. The suspension architecture was redesigned as a fully independent setup to enhance vehicle control and handling dynamics.

Material and Component Upgrades

Multiple carbon fiber elements were incorporated throughout the vehicle. These include the engine hood, rear tail panel assembly, and rear aerodynamic diffuser. The exterior finish is identified as Bootleg Black.

Interior modifications feature three-dimensional printed trim components, Dakota Digital digital instrumentation displays, climate control equipment from Vintage Air, and a carbon fiber steering wheel assembly.

Event Details and Future Status

The Kingpin remains on static display at SEMA 2025 in Las Vegas. The manufacturer has not released statements regarding future disposition of the vehicle. Ringbrothers has not confirmed whether the build will enter production, be offered for private sale, or remain as a demonstration model. Should the company pursue sale channels, pricing considerations would likely reflect the cumulative investment in materials, labor, and specialized components.
