Can one of the cheapest supercars really be a competitive car? It can if that car starts with the Factory Five GTM supercar kit. When you want the ultimate symbol of performance, luxury, and style but you can’t afford a Lamborghini, Ferrari, or Porsche, this kit from Factory Five is the perfect solution. Get ready to get greasy and build a high-performance supercar in your garage.

What makes the GTM one of the cheapest supercars?

Factory Five is an American Kit car company specializing in Shelby replicas. That said, the GTM isn’t based on a Mustang or a Shelby model. The flagship GTM is somewhat unconventional, but it’s also one of the cheapest supercars you’ll find. Of course, you’ll feel like you bought your new supercar at IKEA because you’ve got to put it together yourself.

How much does a Factory Five GTM cost?

The GTM kit is only made in one trim and costs $24,990. This price is an excellent start and it gives you a full body that comes welded together by the manufacturer. The GTM has a low center of gravity, and the kit includes:

  • A high-strength frame painted in gloss black
  • A six-point roll cage for racing
  • A collapsing steering column
  • Side impact bars
  • Front and rear crumple zones
  • Mount plates for the engine, transmission, and pedals

In addition to the basic body parts, the kit includes a sporty suspension setup with KONI shocks and coil-overs paired with Corvette control arms for the front and rear.

What doesn’t come in the kit?

To complete one of the cheapest supercars, you must source some items yourself. Factory Five suggests choosing the LS6 engine and components from the C5 Chevrolet Corvette. In addition to the engine, you’ll need:

  • Fuel tanks
  • A radiator
  • Wheels
  • Tires
  • Sensors to run the engine
  • Transmission

The suggested transmission isn’t from the Corvette. Instead, the company suggests a Porsche G50 transmission for the best performance.

Once you add the items that don’t come in the kit, you’ll likely spend more than $60,000, but you’ll have a complete supercar that doesn’t break the bank.

What car is the Factory Five GTM based on?

The GTM uses running gear from the Corvette and Corvette Z06 sports cars. These proven components pair perfectly with this supercar kit, making it easy to build a unique and impressive car that can provide you with many years of driving pleasure.

How fast is the Factory Five GTM?

Using the stock LS6 engine and a five-speed manual transmission, the GTM can hit 60 mph in only 3.2 seconds. The top speed for this car is 180 mph with this setup and 200 mph when equipped with a six-speed manual transmission. The engine bay can accept the LS1, LS2, or LS6 engine easily, which could allow some owners to tune their GTM to 700 horsepower. That said, Factory Five has found that most owners are on a tighter budget and stick to the stock performance figures.

The Factory Five GTM is one of the cheapest supercars you can build and drive. It could be a great family project or a fun creation that doesn’t put you into the supercar price range.
