Motivated by a supercharged Chevrolet LS1 V8 (providing 450 hp in its most conservative state of tune) routed through a six-speed Getrag manual, the carbon fiber/kevlar-bodied Redback Spyder racer can accommodate two occupants. Enshrouded in Momo-trimmed comfort, would-be racers will find themselves surrounded by a steel and aluminum semi-monocoque spaceframe, kept on the ground via double-wishbones front and rear, with inboard-mounted shocks. Weight? 2,000-2,200 lbs. (depending on the options selected) -- a suitably light, yet rigid frame for mixing it up with the Radical SR3s and Nobles of the trackday world. Asking price is $250K AU, or just under $190,000 USD.
