Renowned custom car builder Ringbrothers showcased its latest creation, the Prestone 1972 AMC Javelin AMX dubbed “Defiant!,” in front of a packed crowd at the 2017 SEMA Show in Las Vegas a mere 12 months after announcing the start of the project. Unveiled in the Prestone booth by Co-Founders Jim and Mike Ring, “Defiant!’ is arguably the wildest custom vehicle design ever crafted by the Wisconsin based car builders thanks to its extreme appearance, cutting-edge construction techniques and four-digit power output.
When Prestone approached Ringbrothers about the idea of building them a vehicle, the Rings already had a canvas in mind – a 1972 Javelin that had been rolling around their home town for over four decades. With an extremely compressed 12 month timeline, the duo decided to rely heavily on Solidworks digital design tools to render the car’s new panels, which were then brought to life in their machine shop and carbon fiber facility.
The Rings extended the Javelin’s wheelbase by moving the wheels forward six and a half inches. The car’s distinctive wheel arches were moved forward and recreated in carbon fiber to pair with a new hood, front fenders, grille and front valance. Other custom details include tail lights, bumpers, trim and engine bay accessories all machined out of blocks of aluminum at the Ringbrothers facility.
“Defiant!” is powered by a Wegner Motorsports 6.2-liter Hemi Mopar Hellcat engine fitted with a Whipple 4.5-liter Supercharger that produces a mind-boggling 1,036 horsepower. A Bowler automatic transmission backs the high-powered engine and a sturdy QA1 Carbon Fiber driveshaft transfers power to the wheels. Royal Purple engine and transmission oil assures the high-powered motor will be kept running smoothly, while a new Dodge Hellcat radiator and fan assembly ensures perfect running temperatures when filled with Prestone Antifreeze. Other engine highlights include a Holley Dominator fuel management system and wiring harness from Painless Wiring. The Javelin’s growl is audible via custom stainless steel Flowmaster headers and exhaust.
The newly extended wheelbase is supported by a Detroit Speed Hydroformed front subframe originally engineered for a Camaro. The Rings installed Detroit Speed rack and pinion steering, as well as front sway bars and RideTech shocks for a smooth ride. The front suspension is complemented by a Chevy 12-bolt rear end fitted with a custom four-link suspension built by the Rings.
Key interior features include a Kicker sound system, Classic Instruments gauges, a Vintage Air Gen IV Magnum Evap Kit and custom seats by Upholstery Unlimited. “Defiant!” rolls on a set of HRE Performance Wheels sized at 20×11 in the front and 20×13 in the rear, all wrapped in Michelin tires sized 285/30/20 up front and 335/30/20 out back. With more than 1,000hp on tap, the Javelin requires massive stopping power, so a set of six-piston caliber Baer brakes are installed to bring the car to a stop.
To finish the look of the car and highlight the body work, the exterior of “Defiant! is coated in a rich, BASF Glasurit color named “Jalop Gold.”
