One of my favorite custom car shops is the Wisconsin-based duo of Mike and Jim Ring, and their shop Ringbrothers.
The brothers made their debut at the 2005 SEMA Show, and in 2006 captured the Mothers’ Polish award for their customized 1967 Mustang nicknamed “Reactor.” In 2014 they won a Chevrolet Best of Show award for their 1966 Chevelle “Recoil.”
The shop builds one to two cars per year, which are highly customized with one-off parts. What sets them apart from other builders is their attention to detail, and their impressive ability to manufacture custom parts using everything from carbon fiber to 3D printing to CNC machining.
Since 2005, their custom car shop has expanded as a parts supplier of high quality hood hinges, door handles, hinges, and other hardware.
After sitting out the 2020 and 2021 SEMA shows, the Ringbrothers returned to SEMA 2022 in a big way, with four full custom builds on display throughout the show.
One project that caught my eye was the 1969 Ford Mustang Mach 1 “Patriarc” which was on display at the Centerforce booth. 
The car starts with the 580-horsepower 5.2L V8 “Aluminator” crate engine from Ford Performance, coupled to a Bowler Tremec T-56 Magnum six-speed manual gearbox and a Strange Engineering 9-inch rear end.
The car rides on a set of Ringbrothers signature G-Code wheels that were developed with HRE for the G-Code Camaro in 2016. The wheels are wrapped in Michelin Pilot Sport 4S tires. 
Handling is vastly improved thanks to an independent front and rear suspension using Roadster Shop Fast Track components with Penske Racing RS Edition coilovers. A Baer disc brake system with six-pison calipers and massive 14-inch rotors provides serious braking force.
Build time on the Patriarc Mustang is over 5,000 man hours. The body was widened two inches in every direction, and the rear quarter panels have been lowered. This required fabricating a new floor pan and transmission tunnel from sheet metal. While they were in there, they added a roll cage, too.
The list of carbon fiber parts includes the air scoops, hood, and rear diffuser.
It is impressive that after building more than a dozen different one-off Mustangs, the Ringbrothers continue to push the boundaries of the resto-mod world with their creations. The Patriarc Mustang Mach 1 is a remarkable car from every angle.
