Defiant ~ 1,100HP 1972 AMC Javelin AMX Custom Muscle Car

This 1972 AMC Javelin ~ named “Defiant!” ~ is arguably the wildest custom vehicle design ever built by the Ringbrothers.

When Prestone approached Ringbrothers about the idea of building them a vehicle, the Rings already had a canvas in mind – a 1972 Javelin AMX that had been rolling around their home town for over four decades.

With an extremely compressed 12 month timeline, they 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.

They 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.

To finish the look of the car and highlight the body work, the exterior of Defiant is coated in a rich BASF Glasurit 55 Line “Jalop Gold”
