Jim and Mike Ring discovered their passion for cars at 10 years of age. As teenagers, they were building innovative machines and painting vehicles every time they could, using their parent's basement as a little shop. The real shop, headquartered in Wisconsin, serves as a collision and repair station in addition to delivering custom builds. Ringbrothers accessories create a unique look that stands apart. Their line of carbon fiber body parts helps car enthusiasts to incorporate Ringbrothers style in their own builds.
Jim and Mike Ring have created a catalog of gorgeous and fast cars that left their workshop. However, they only produce one or two custom vehicles per year. They also make and sell custom car parts and perform repairs, keeping unique builds as a hobby. Moreover, they host the DIY series "Ringbrothers University" where they teach beginners to build cars. These are the sickest cars from Ringbrothers EVER.
15 Valkyrja
The heart of the Valkyrja is a 416-cubic-inch LS3 engine topped with a 2.9L supercharger. The Flowmaster Stainless Steel Super 44 Series exhaust is bolted to the engine. 890 horses get to the rear wheels through a six-speed gearbox. The Valkyrja also features a robust suspension and a beefy rear end.
14 Defiant!
The Defiant! is a Javelin AMX on steroids. Under the hood is a tuned version of the Hellcat's 6.2L V8 topped with a 4.5L supercharger to raise power from the Hellcat-standard 707 hp to 1,100 hp. All that power is sent to the wheels through a four-speed automatic transmission. Stopping power comes from six-piston brakes.
13 Ballistic
What makes the Ballistic a lot of fun is the tuned 5.8L V8 engine donated by a Shelby GT500. Thanks to Flowmaster Mufflers and a custom stainless steel exhaust system, the car is loud and aggressive. To beef up the Ballistic even further, Ringbrothers added the 9-inch Ford-style rear and a QA1 driveshaft.
12 SPLITR
The SPLITR comes with a naturally aspirated 7.0L Ford Racing engine modified by Wegner Motorsports and matched to a T56 Tremec manual transmission. The exact power output is unknown, but we bet it's higher than 500 hp. For better handling, Ringbrothers asked Detroit Speed to create "a custom Mustang Aluma-Frame front suspension."
11 Blizzard
According to Mike, "The Blizzard is the first car we’ve built with carbon-fiber doors. In fact, numerous other pieces on the car are carbon fiber, including the hood, roof, trunklid, rear bumper, and side scoops. The G.T. 350 R-model-style front fascia is made of aluminum. We eliminated all the pinch welds throughout the body."
10 Dragon
The Dragon features a ROUSH 427 IR motor that delivers 585 hp and 545 lb. ft. of torque. The entire body was built from carbon fiber and machined billet. The massive Baer Pro Plus brakes come with a brake line lock. The unibody design was replaced with a custom frame with belly pans.
9 Reactor
The Reactor is a far-cry from a typical custom build. According to Ringbrothers, there are 70 custom parts, including the front spoiler vents, the hood bezel, and the gas cap, not to mention numerous carbon-fiber details: the front and rear bumper, the rear taillight panel, and the front lower valance.
8 Defector
Under the hood of the Defector is a 6.4L Hemi V8 – the same that you can find in a Charger – tuned by Wegner Motorsports and paired with a Flowmaster exhaust system for a mighty rumble. This is the first Ringbrothers build based on a Mopar product, and they say it took 4,700 hours of work.
7 Producer
Under the hood of the Producer is a Keith Craft 427 stroker. The brothers wanted to keep the old-school vibe of the Mustang, so they built the engine the old-fashioned way to reach 740 horsepower. Jim and Mike even designed the three-piece wheels. Only the grille is original, all other parts are custom.
6 Razor
Under the carbon fiber hood of the Razor sits a legendary Ram Jet ZL1. Output is rated at 520 hp and 493 lb. ft. of torque. To handle this power, the Razor features a Tremec six-speed transmission driving the rear wheels. The two-tone paint scheme helps the car stand out even more.
5 Switchback
In the Switchback, the Mustang's standard 5.0L engine got a ProCharger supercharger system with Hose Candy sleeves and Flowmaster headers. Ringbrothers installed a 409S dual exhaust system to increase the power output from an already impressive 430 hp to an insane 575 hp. The carbon-fiber body kit was installed for a more aggressive look.
4 ADRNLN
Under the hood, the ADRNLN features a Wegher Motorsport LS3 V8 delivering 600 horsepower and paired with a ZF five-speed gearbox. The V8 breathes through a Flowmaster stainless steel exhaust system, and all the horses come to a rest thanks to HRE three-piece forged wheels. According to Ringbrothers, the interior was inspired by Nike.
3 Espionage
With the looks fit for a Bond movie, the car also got a massive engine. Lift up the hood and you'll see a huge "427ci Wegner Motorsports V8 plus a 2.9-liter supercharger." Unsurprisingly, the power figures are insane – 959 horsepower and 858 lb. ft. of torque. Frankly, the car got plenty of stopping power, too.
2 Madam V
The Madam V started with a 1948 Cadillac Coupe, a 2015 ATS-V, and a 2016 ATS-V. Ringbrothers tweaked the ATS underpinnings and pushed the front forward 16 inches, rebuilding most parts in carbon fiber. Despite excessive modifications, they managed to keep the entire ATS-V 3.6L biturbo V6 drivetrain and even some original exterior features.
1 UNKL
The UNKL is a 1969 Ford Mustang Mach 1 that packs a powerful V8 engine, a ton of carbon fiber, and a widened stance. Under the hood sits a 700-hp unit built by Jon Kaase Racing Engines, sending power to the rear wheels through the six-speed Tremec transmission and a carbon-fiber driveshaft.
