The GTM Supercar kit is engineered to be built. We have a solid technical support team to help you make it through the process. Here are some frequently asked questions to help you get started and learn more about the GTM Supercar kit.
What engine does the car use? The GTM Supercar utilises the power plant from a C5 Corvette – the LS1 or LS6 (Z06 Corvette).
Can I use a different engine? To date, we have not built a GTM Supercar using a non LS platform engine.However, we have built a GTM Supercar using the potent 505 hp LS7 from the C6 ZO6 Corvette. Call or email us for the details on parts and modifications necessary to bolt this Ferrari killer into your GTM Supercar !
What type of transmission does the GTM use? The transmission is a G50 from a 1990-1998 Porsche 911.
Can I use a different transmission? We are looking into adapting other transmissions. If we find a suitable transmission, we will not change the configuration of the kit in such a way that will not allow the G50 to be used but rather update the frame to accept the other units.
How fast is the car?
We have tested the car extensively on the track Summit Point raceway (Jan 2005) and (July 2005), and Bondurant (Jan 2007), but the tests have been more functionality based than performance based. While the focus of the initial testing sessions were occupational in focus(heat management, visibility, handling, interior noise, etc), we couldn’t resist pushing the prototype close to its limits. At Summit Point we were astounded at the handling, performance and track manners of the car. During this testing, however, we did not record any acceleration or braking data.
At 2,240 lbs ready to drive (weighed on scales without driver) and with the engine sitting squarely over the rear axles, our best estimate (based on years of working with similar weight/hp custom race cars) is that the car is sufficiently fast enough to qualify as a legitimate Supercar. When pressed, Jim Schenck (FFR engineer and design team leader of the GTM Supercar project) projects a 0-60 mph time in the mid 3’s and a ¼ mile time in the 11 seconds range… that’s with a stock Corvette engine producing 350 hp.
How much does the kit cost?
The GTM Supercar Complete Kit requires just three things to finish… 1. Engine/transmission, 2. Wheels, and 3. Paint. Your selection of these parts and what you pay for them will determine you completed vehicle cost.
Can I purchase a completed GTM?
We only sell the chassis and body kit parts. However, we do know of a network of small hot rod and custom shops that will inevitably build completed race and street cars for customers. E-mail us for a list of such businesses at enquiries@factoryfive.co.uk
Note: The companies referred to potential customers are separate and independent companies and Factory Five Racing does not warranty their parts nor workmanship.
How much does it cost to build a GTM?
The price of the kit is not as important as the price of the completed vehicle. We estimate that most customers will spend between £50,000 and £60,000 to complete the car including Chevrolet parts, wheels/tyres, paint and the Porsche transaxle.
What is included with the kit?
See “What you get”
What IS NOT included with the kit?

Does the GTM have roll-up windows?
Yes. The GTM has power GLASS side windows.
Does the GTM use the Corvette chassis?
No. The GTM frame is designed and manufactured by Factory Five Racing. It is a steel tube and aluminium panel construction.
How long does it take to build the car?
We have only built (and rebuilt!) two prototypes to date. Therefore, a lot of designing was done concurrently with the build which lengthened the build time considerably. We are spending huge amounts of our time developing/building the car, so you don’t have to! We estimate it will take the average builder about 250-300 hours (estimated) to complete the project.
Will I fit in the car?
This is another area where we have spent many hours developing and testing to be sure that the car accommodates a wide array of people regardless of height and weight. After completing chassis #3 (red, LS7-powered car in photos) and driving the car, we feel the comfort range is for people up to 6’ 3” tall and weighing less than 275 lbs.
Does the GTM have heat and air conditioning?
The A/C system is available as an option. The system was designed by Vintage Air in conjunction with our engineers specifically for use in the GTM.
How loud is it in the cockpit?
We haven’t measured decibels, but during our track test and from driving the car in the area around our facility we have found that the noise level in the cockpit is less than we expected. The engine noise is remarkably low and the over-all feeling is more street-car than race car. We do have more work to do to insulate the cockpit and plan to perform some additional tests to conform to NVH (Noise Vibration Harshness) standards.
