Doesn't this look like more fun than a barrel of monkeys? Isringhausen’s latest Porsche Cayman GT4 racecar is not a factory Clubsport, but rather a fresh build by Bilt Racing Service that started as a new GT4 straight off the showroom floor. Built to compete in PCA, SCCA, and NASA club racing, it features a 63-inch carbon fiber wing, big front splitter, triple-adjustable remote-reservoir KW Suspension coilovers, custom T45 roll cage, CSF 3-piece radiator, Performance Friction brakes, Pirelli P-Zero racing tires, and 18x9/18x10.5 Forgeline one piece forged monoblock GS1R wheels finished in Satin Gunmetal!
