Building A Legend


street_modelJust how does a Shelby Cobra, 4000, 7000, or 8000 Series car or Challenge Racer get built?

We are going to take you step by step through the process of building one of these unique vehicles. From the raw steel to the last coat of wax, you are going to have an insider’s view of the meticulous care and extraordinary craftsmanship that goes into each car that Finish Line Motorsports, Inc. produces. As an added treat, when it is time, we are going to try to get permission to take you inside Kroyer Racing Engines to see how the motors for our cars are built.

As with all quality things, a Cobra begins with the best materials we can buy. Our 4000 Series street car frames and bodies come directly from Shelby American. Our superb craftsmen assemble them with the utmost care

All Challenge Racers are made EXCLUSIVELY in our shop. Those chassises are made by us. The superstructures are made from chrome-molybdenum alloy steel for added safety and strength.. The 120 wall 4 inch frame rails are supplied by Shelby American. We then add the rest of the framing in the form of 95 wall 1.25 inch steel on our street models and 95 wall 1.5 inch steel on our Challenge racers. This insures that any version of our Cobra you buy is made with the strongest, most reliable steel framing available.

Pieces are labeled as belonging to a particular chassis number and stored until required for assembly. Sub assemblies are made and then the process of final frame assembly begins.

After careful research, we have found that T.I.G welding produces a superior join of the steel. It is the strongest weld possible when working with chrome-molybdenum alloy.

Final frame assembly is done on a Rapidline Frame jig. We chose Rapidline because they are the industry leader. To guarantee maximum precision and repeatability, Finish Line Motorsports, Inc. craftsmen have developed special fixtures for the Rapidline jig. These fixtures are unique to our fabrication shop and ensure that your Cobra is made to the same precise standards that characterize our Challenge Racers.
