Historically Porsche has always been a brand well-represented by customer and privateer teams in motorsport. It could be argued that the modern-day formula for mass-production GT racing cars was pioneered, developed and wholly built by Porsche with the advent of the Cup cars back into the late 80s. Still, as modern GT racing has become more and more cost prohibitive and fewer teams, companies or individuals either can’t or choose not to foot the bill, the number of privateer teams running the top-level GT 911, the RSR, can be counted on one hand. That number next year may well fall to zero. Team Falken Tire has announced that with the completion of the 2015 IMSA Tudor United Sportscar Championship they will officially end their RSR program.
