For almost 15 years Kirkham has been manufacturing the finest aluminum bodied roadsters in an old jet fighter factory in Poland. They have an enviable reputation in the industry for stunning aluminum bodies and their sophisticated billet suspension made in-house on the latest CNC equipment and CAD design software.
Kirkham rolling chassis are built with all new parts and do not mix and match parts from “donor” vehicles. The systems on their cars such as brakes and steering are designed and engineered from the ground up and work with companies such as Penske Racing Shocks and Wilwood Brakes.
Kirkham supplies Shelby with their aluminum bodies and frames for the the vast majority of their aluminum bodied CSX 4000 series cars. Their cars are so accurate they provide replacement body panels and chassis parts to many customers to restore their own original Shelby Cobras.
Their suspension control arms have evolved from complex tubular steel units with antiquated bearings and bushings into extremely lightweight CNC machined billet parts with modern sealed bearings and permanently lubricated wear surfaces.
Kirkham hubs are a true pin drive “knock off” design that has benefited from Formula 1 technology. The hubs are no longer made of 4340 chromoly but of heat treated 17-4 PH stainless with a tensile strength of 200,000 psi. This exotic alloy is 4 times more expensive to buy than chromoly. Where others use a cheap fiberglass bucket they use a complex welded tubular frame. Its the only way to build an authentic seat.
Kirkham Motorsports History.
Kirkham Motorsports was founded in 1995 with the mission to build the finest replicas in the world. It all began when brothers, David and Thomas Kirkham, were restoring their own Cobra, CSX3104. At the same time, a relative bought and imported a Polish fighter jet and invited them to see this relic of the Cold War. As the brothers looked at the airplane, they couldn't help but notice the striking similarities between it and CSX3104. They wondered if the people who built the plane could build an exact replica of a Cobra. They found the name of the manufacturer and sent them a fax. The simple note they scribbled read, "Can you guys build an aluminum bodied car?" Within 12 hours, they received the reply, "No problem."
A week later, David was on an airplane to Warsaw with an English-Polish dictionary, a toy model of a Cobra, and a dream. He spent a week scouting the factory and exploring their manufacturing abilities. He saw a silent factory with idle machines. The enormous factory had produced aircraft for over 60 years. During the tour, David knew this was the place he wanted to build cars. After meeting with three generations of skilled craftsmen eager to make these cars, he forged some agreements and left filled with high expectations and enthusiasm.
Since that trip over 10 years ago, Kirkham Motorsports has become one of the leading manufacturers in the component car industry. At the inception of the company, KM focused on building the most accurate replicas in the business. Kirkham Motorsports still offers incredibly accurate replicas, but technology and manufacturing techniques have evolved since the 1960’s. KM is an engineering focused company and has been able to push the performance envelope without forgetting originality.
