Superformance Mk II 289 Cobra
RSR 2001 Installation

Superformance Mk II

The development of the Mk II is the brain child of Ross Henry. Working with old friend Jim Price of Hi-Tech Automotive, Ross has developed accurate replicas of the 289 Cobra transverse leaf spring race cars. Two models will be produced, FIA (European spec) and USRRC (USA spec).

The Superformance Mk II FIA and USRRC are distributed by Superformance LLC and licensed by Carroll Shelby Licensing Inc.

In mid-May, the first production car, RSR 2001, an USRRC spec racer, arrived at Olthoff Racing for setup and drive train installation. The photos here were taken during that process.





The USRRC (United Stated Road Racing Competition) was basically a racer spec. A number of modifications were allowed such as racing windshields, elimination of the passenger grab handle, suspension changes such as the heim joint suspension, and a custom dash layout.

RSR 2001 is a USRRC spec car.



The FIA (Federation Internationale de l'Automobile) specs are more production based requiring production components in the suspension and drive train, a production windshield, and dash grab handle, to mention a few. The FIA also required that a standard suitcase fit in the trunk.  Legend has it that when the suitcase did not fit, someone slammed the aluminum skinned trunk on the suitcase and produces the two dimples in the racer's trunk.
