Wisconsin’s own Ring brothers (Jim and Mike) have been turning muscle car restoration on its head since 1994, when frustration with subpar aftermarket parts pushed them to begin CNC-machining their own components. Fast forward three decades and Ringbrothers has become a preeminent name in restomod builds, known for not just restoring classics but reimagining them entirely. Their latest SEMA reveal, a 1969 Ford Mustang Mach 1 they’re calling Kingpin, proves they’re still at the top of their game.
Sinister By Design
The Mustang Mach 1 already had attitude when it debuted in 1969, but Ringbrothers took that aggression and amplified it to supervillain levels. Jim Ring said they asked themselves what the final boss in a John Wick film would drive, and Kingpin was the answer. Draped in BASF’s custom Bootleg Black with Grab-Her Green trim (a cheeky riff on Ford’s Grabber Green), the car looks like it rolled straight out of a crime thriller.
Performance Underneath
Under that custom carbon-fiber hood sits a Wegner Motorsports 5.0-liter Coyote V8 with a Whipple supercharger churning out north of 800hp. Power routes through a Bowler Carbon Edition six-speed manual to the rear wheels — yes, an actual manual transmission. The Roadster Shop FAST TRACK Stage III chassis was converted back to unibody construction, then widened 2″ up front and 3.5″ at the rear. The wheelbase got stretched forward 1.5″, and a custom roll cage adds both safety and rigidity.
Massive Michelin Pilot Sport 4S tires (295/35R19 front, 345/30R20 rear) mounted on HRE Vintage Series 517 wheels provide the grip, while six-piston front and four-piston rear Brembo brakes handle stopping. Fox RS coilovers and independent suspension front and rear give this thing incredible handling.
Beauty Is More Than Skin-Deep
Inside, Kingpin features a Ringbrothers ENYO steering wheel with a crushed-carbon hoop, Dakota Digital custom gauges, and a Vintage Air climate system because even villains deserve to be comfortable. The carbon fiber work extends throughout, including on the hood, grille surround, rear diffuser, lowered rear quarter panels, and various interior touches. Multiple 3D-printed and machined billet components showcase the 5,500 hours Ringbrothers invested in this build.
