When Porsche introduced the 911 series, it was clear the new six-cylinder model needed to compete in motorsports. While Porsche focused on European events, privateer teams brought the 911 to the U.S. Despite winning the 1966 SCCA D Production National Championship at Riverside with a 911S, Porsche struggled to win over American enthusiasts, especially former 356 owners.
Porsche’s racing department developed a list of competition-oriented parts that could be homologated for SCCA’s C Production class, resulting in the “Sports Purposes” catalog. The catalog included the “Rally Kit Option 9552” and various “Tuning Packages.”
The Rally kits featured items like Recaro racing seats, a bolt-in roll bar, skid plates, lightweight interior modifications, adjustable Koni shocks, competition brake components, and a limited-slip differential. Tuning kits increased engine power from 160 hp to over 180, making these special 911Ss close in performance to Porsche’s lightweight 911R racers.
