Rennsport Reunions don’t happen every day. In fact, they don’t happen every year. It’s every five years that enthusiasts gather to celebrate the world’s most famous sportscar marque at Laguna Seca in California, and at these events Porsche tends to debut something special. Last time, it was the new 935. This time? Meet the Porsche 911 GT3 R rennsport, the ultimate expression of a shackle-less Porsche 911 race car, with more than a few nods to the marque’s illustrious past. It’s also probably set to be the most incredible customer-only naturally-aspirated Porsche that will ever be made.
