Based on a beautiful 1990 Porsche 964. But not much will remain original. This is the prototype to reach the perfect combination between the lightweight body of the KALMAR 7-97 and versatile usage of the KALMAR RS. We called it the KALMAR Automotive RS-R. Super low weight high power and monster tires ! wait and see. Built specifically for a customer couple who will use the car on the Beyond Adventure and Spirit of Speed by Tom Kristensen events. Operated by KALMAR Automotive.
