One of the most exciting parts of SEMA every year is getting to see what the Wisconsin based builders Ringbrothers are going to transform next. Known for their incredible custom muscle cars, the team at the brothers Ring never disappoint in Las Vegas. Based on this year’s SEMA-revealed 1969 Ford Mustang Mach 1 muscle car known as UNKL, we don’t think they are going to start any time soon.
This highly modified 1969 Ford Mustang Mach 1 got its namesake as a tribute to the customer’s uncle who inspired a lifelong passion for cars. As far as gearhead tributes go, it doesn’t get much cooler than this stunning Ringbrothers muscle car.
The shape of the classic Mach 1 has been highly modified, while retaining enough to make it instantly recognizable. While a number of the panels are made from reshaped steel, others are crafted from carbon fiber which helps to shave some weight from the Mustang. Overall the body gains an inch of width on each side, which gives the car a sportier and more aggressive look. The custom BASF “Big Boss Blue” paint certainly doesn’t hurt in this department either.
Ringbrothers make some beautiful cars, but don’t think for a second that they skimp on performance. Under the large scooped hood sits a naturally-aspirated 8.5L V8 engine built by Jon Kaase, featuring Holley carbs, Flowmaster headers and a Flowmaster 44 stainless steel exhaust system. The 520 cubic-inch (!) motor is good for a maximum of 700-horsepower, mated to a Bowler six-speed manual Tremec gearbox. Power is routed to the rear wheels via a QA1 carbon fiber driveshaft linked to a 9-inch John’s Industries rear end with a 3:55 gear set.
Detroit Speed Engineering provided a custom front and rear suspension with RideTech coilovers, as well as new sway bars front and rear. Other modifications include a new rack-and-pinion steering rack, a staggered set of 19- and 20-inch HRE wheels shod in Michelin Pilot Sport 4S tires, and six-piston Baer Extreme calipers handling stopping duty at all four corners.
Inside the Ringbrothers Mustang Mach 1 you’ll find a stunning racing inspired interior done by Upholstery Unlimited. Features include Recaro seats, Classic Instruments gauges, a Momo steering wheel, an Ididit steering column, a Vintage Air evap kit and a custom Kicker sound system. Ringbrothers finished the interior off with a number of custom billet parts such as the race-style red switches on the dash.
The 1969 Ford Mustang Mach 1 by Ringbrothers will be on display at the Flowmaster/Holley booth at SEMA 2019.
