Ringbrothers Mustang Mach 1 Build Debuts at SEMA Show

Ringbrothers has unveiled its latest creation, a 1969 Ford Mustang Mach 1 dubbed “PATRIARC,” the custom car builder and parts manufacturer announced.

A result of over 5,000 build hours, the PATRIARC combines a modern drivetrain, suspension and chassis with the build quality and custom work Ringbrothers is known for, the builders said.

A complete reimagining of the original Ford Mustang Mach 1, PATRIARC has performance levels well beyond those thought possible in 1969, Ringbrothers said, with power delivered from a Ford Performance Aluminator 5.2 XS engine producing 580 horsepower and 445 lb-ft of torque. That power is transferred to a Strange Engineering 9-inch rear end via a Bowler Tremec T-56 Magnum six-speed manual equipped with a Centerforce clutch. Grip comes from sticky and wide Michelin Pilot Sport 4S tires wrapped around HRE Wheels G-Code Edition wheels. Penske Racing Shocks RS Edition coilovers and independent front and rear Roadster Shop FAST TRACK suspension team keep the Mustang Mach 1 glued to the ground. All of it is stopped by Baer Brakes 14-inch rotors and six-piston calipers.

“This year has been an amazing one for Ringbrothers with four vehicle debuts at the 2022 SEMA Show,” said Ringbrothers co-owner Mike Ring. “PATRIARC is one of them and showcases our capabilities, levels of craftsmanship and engineering when reimagining what this iconic car could become. It is modern performance, capability and comfort wrapped in a classic American exterior.”

“The Mustang Mach 1 has always been an aggressive-looking car, and we wanted to add to those classic good looks with subtle but critical changes,” added Ringbrothers co-owner Jim Ring. “Over 5,000 hours went into building PATRIAC and perfecting the aesthetics. And, like all our builds, it has the performance to match its new-found aggression. Teaming with our trusted partners BASF, Motul, Miller Welding, Painless Wiring, GFS and others helps make it all possible.”

Wrapped around the Roadster Shop FAST TRACK Stage III chassis converted to unibody is the original Mustang Mach 1 body extensively modified by Ringbrothers. It was widened by two inches in every direction, and the rear quarters were lowered. A new floor pan and transmission tunnel were fabricated before a fully bespoke interior and a roll cage were installed. The interior features upholstery and trim work by Avant-Garde Interiors and includes a Vintage Air Gen IV Magnum climate control system, gauges by Dakota Digital, and a custom-made Ringbrothers “The Elder” carbon-fiber hoop steering wheel.

Custom carbon-fiber components abound with rear side scoops that direct air over the taillights, along with a hood and rear diffuser made from the high-strength material. Billet and 3D-printed parts include a one-off rear bumper, seat backs, armrests, door panels, emblems and a host of others.
