GTM

The Factory Five GTM (Grand Touring Mid-engine) represents an ambitious kit car supercar featuring mid-engine layout and exotic styling at accessible pricing. Designed to accept GM LS-series engines from the proven 350 HP LS1 through potent 430 HP LS3 to 500+ HP LS7, with tuning potential exceeding 700 horsepower, the GTM delivers extraordinary performance from its lightweight construction. Weighing just 2,250 lbs fully built with power outputs ranging from 350-400 hp in stock form, the GTM achieves 0-60 mph in 3.2 seconds, quarter-mile in 11.0 seconds at 132 mph, and top speeds of 180 mph with 5-speed manual or 200 mph with 6-speed manual transmission. The power-to-weight ratio enables handling of 1.05g lateral acceleration and 166 feet stopping distance from 70 mph.

The MIG-welded high-strength mild carbon steel tube frame accommodates either Porsche 911 transaxle or Mendeola 5-speed, paired with lightweight aluminum Corvette control arms and KONI shocks. The GTM kit priced at $24,990 requires approximately $50,000 total including engine and completion, yet delivers performance exceeding supercars costing multiples: faster than Dodge Viper ACR, Porsche GT, Saleen Twin Turbo S7, and Ford GT. The combination of exotic mid-engine design, proven LS V8 power, professional-quality construction, and extraordinary performance-per-dollar makes the Factory Five GTM one of the most compelling kit car supercars available, offering genuine supercar performance and styling at sports car pricing with strong enthusiast community support.
