Ringbrothers’ 1969 Mustang Mach 1: “Kingpin/Authority” Build

Ringbrothers unveil their "Kingpin/Authority" 1969 Mustang Mach 1 at SEMA 2025, featuring a Roadster Shop chassis, custom carbon fiber body, and a supercharged 800hp Coyote engine. Interior is totally redone.

Unibody Transformation

The Ringbrothers went also better: They transformed the body-on-frame Mustang to a unibody chassis, making use of a Roadster Store platform as the base. Roadster Shop’s framework features double wishbone suspension and Fox RS coilovers for enhanced handling.

Some of the best (and some of the jankiest) builds in the vehicle cosmos all gather in Las Vegas for one huge aftermarket face-off. Each year, Mike and Jim Ring bring something great to SEMA– for 2025, it’s the “Kingpin” 1969 Mustang Mach 1.

Aggressive Aesthetic and Carbon Fiber

The Mach 1 body is two inches wider at the front and 3.5 inches larger at the rear, and the wheelbase is 1.5 inches much longer. Carbon fiber accents decorate the outside, which is surprisingly tame for a Ringbrother’s construct. A lot of the Mustang’s initial aesthetic remains, yet whatever has actually been massaged for a much more ominous look. The rear valence and illumination are absolutely customized, while a lot of the Mustang looks acquainted– albeit subtly altered.

Interior and Safety

The inside is totally redone with Dakota Digital determines, Vintage Air cooling, and a customized guiding wheel. A personalized roll cage, fully incorporated and hidden, protects passengers and includes rigidness, while the personalized dashboard includes gorgeous transparent elements and 3D-printed parts to modernize the timeless inside.

Power and Drivetrain

In common Ringbrothers style, this Mustang is completely redone from the ground up. It makes 800 horsepower from a Whipple-supercharged Wegner Motorsports 5.0-liter Prairie wolf engine, and it sends out power to the back wheels with a Bowler six-speed handbook gearbox.
