Custom-built for an exclusive client of Fox Marketing, "The Black Mamba" is based on the Lexus IS F and features a sinister Onyx Black exterior, contrasted by an Alpine White interior with black stitching, and smoked rear taillights. It also boasts full sheet-metal wide-body rear flares, plastic welded side skirts and rear bumper cover, and sits on a set of 20-inch iForged Performance Flux alloys with custom white bolts and wrapped in Toyo tires.

An unspecified boost in performance is provided by a rear-mounted twin-turbo kit by Turbonetics, which comes with a custom blow-off valve and oil pump. Completing the package is a set of 2012 Lexus headlights with daytime running lights and Factory Lexus big brakes. Company founder Brian Fox calls the result the first widebody twin-turbo IS F in the world.
