The Kastner Cup was named in recognition of the career accomplishment and legacy of R.W. “Kas” Kastner who passed away on April 11, 2021 at the age of 92. Kas Kastner was one of the most influential individuals responsible for the racing success of Triumph sports cars from the late 1950’s through 1970 and beyond. To this day, his series of Competition Preparation Manuals are a must read for competitors in Triumph sports cars. Later in his career, Kastner directed the Nissan IMSA GTP team that won the manufacturers’ championship three years in a row and the drivers’ championship four years in a row; a remarkable achievement.
