Um, they managed to do it for the Challenger Drag Race Package. It is possible, but it's all about how far you are willing to go with the trimming...

Mopar shortened the Challenger's 116-inch wheelbase half an inch and cut weight by eliminating the windshield wiper assembly, complete HVAC system, all airbag components, the rear seats, the power steering system, exhaust system and underbody heat shields, cross-car and side impact door beams, rear bumper beam and rear deck lid spoiler. Mopar even removed the body sealer, sound deadener and undercoat from the factory, and achieved a final weight that's 1,000 pounds lighter than the standard SRT8, which weighs 4,152 pounds.
