Randy Franklin Pobst (born June 26, 1957, in Dayton, Ohio), also known as "RFP" or "The Rocket," is an American race car driver and journalist for Motor Trend magazine.
Active in the SCCA World Challenge GT series and the Grand American series' GT class, Pobst was the 2003, 2007, 2008, and 2010 SCCA World Challenge GT champion, the 1996 North American Touring Car Championship title winner, and the 2005, 2006 and 2007 SCCA World Challenge TC vice-champion. He is also a two-time class winner of the 24 Hours of Daytona, in 2001 and 2006.
Randy Pobst has more than 90 pro wins. He is currently a Mazda, Volvo, Audi and Porsche factory supported driver.
In this follow-up video at Circuit of the Americas (COTA), we welcome back Randy Pobst to drive my GT4 RS, now modified with Dundon parts based on his initial feedback.
Did these changes address his concerns—and did they make him faster on track, as they did for me? It’s time to find out!
We didn’t just hand him the car and walk away. We worked closely with Randy to dial in the setup to his liking: adjusting compression and rebound, repositioning sway bars, adjusting aero, and tweaking ride height to get the most out of the car.
By the end, the car felt even more compliant, but was it enough for a record lap? Watch and find out.
