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. Our original target was that a guy should be able to build the GTM for less than $30,000. We think that is still achievable if a donor C5 is procured for less than current market value of $8,000-$10,000, and the customer can do his/her own paintwork… but realistically we estimate that most folks will spend between $35,000 and $45,000 to complete the car including Chevrolet parts, wheels/tires, paint and the Porsche transaxle.

Lightning in a World of Thunder



In a world where thundering Supercars routinely crest 3500 lbs, the track-tested and tuned 2350 lb. GTM is a refreshing return to sportscar fundamentals. Factory Five lightning strikes with a hp/wt ratio similar to that of a Daytona Prototype. With a stock LS7 powerplant, the car maintains a 4.8 lbs per hp ratio. Connected to the pavement via huge 335 series rear tires, it enjoys acceleration numbers better than almost any production vehicle on the road today.



The GTM is faster 0-60 mph than a Ferrari Enzo, a Porsche GT, a Saleen Twin Turbo S7, a Ford GT, and a Lamborghini Mucielago*! The GTM even beats out a Champ car to 60 mph! **



0-60 in 3.0 seconds!



0-100 in 6.6 seconds!



¼ mile in 11.0 seconds @ 132 mph!



But a Supercar isn’t just defined by acceleration. The GTM’s ultra-stout, ultra light space frame chassis and deep breathing LS Series V-8 power combine with modern suspension and brake components to deliver Supercar performance in braking and roadholding as well.



The GTM stops and turns just as fiercely or moreso than the rest of the Supercar gang. With stock Corvette brakes, the GTM slows to a stop from 70 mph in only 166 feet, outbraking the mighty $157,000 Ford GT. That was STOCK Corvette brakes, not $30,000 carbon/ceramic.



Want roadholding? The GTM turns faster than it falls thru the air. Car and Driver measured a phenomenal 1.05 lateral G on street DOT tires. To put that in context, the Ferrari Enzo is the only car that matches it!



The car is light and aerodynamic, with excellent weight distribution and precise race-car handling/braking derived from the Chevrolet Corvette C-5. The car uses potent GM LS series engine power and Corvette suspension/brakes with Koni brand coil-over shocks and a Porsche 911 transaxle to get the job done.

GTM Supercar
Frequently Asked Questions


What engine does the car use? The GTM utilizes the power plant from a C5 Corvette – the LS1, LS2 or LS6 (Z06 Corvette).



Can I use a different engine? To date we have not tested other engines as we are focusing on the current LS configuration.



What type of transmission does the GTM use? The transmission is a G50 from a Porsche 911. On average, you can purchase a used G50 for roughly $2,500 - $3,000.



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 (Jan. ’05 Summit Point raceway), (July 21, 2005), and (Jan 2007 Bondurant) but the tests have been more functionality based than performance. 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 will be sufficiently fast to qualify as a legitimate Supercar. When pressed, Jim Schenck (FFR engineer and design team leader of the GTM 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 will the kit cost?

Launch price is $19,990 for the kit.



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 info@factoryfive.com.



Note: The companies referred to potential customers are separate and independent companies from Factory Five Racing and we do not warranty their parts or workmanship.

What is included with the kit?

See “Standard Parts list”



What IS NOT included with the kit?

See “Parts to Complete List”



Does the GTM have roll-up windows?

Yes. The GTM has roll-up or 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 aluminum 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 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 more quiet 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 perform some additional tests to confirm NVH (Noise Vibration Harshness).
