After making an early splash in Formula Ford, Formula Atlantic and Super Vee, Cobb was on the verge of quitting the sport. Then Rob Dyson asked if he’d like to drive his Porsche 962 in the IMSA Camel GT series. Co-driving principally with Dyson and James Weaver from 1985-1988, Cobb won three consecutive Porsche Cups and scored eight victories, four seconds and nine thirds in 49 starts. In 1989, Tom Walkinshaw hired Cobb to drive for the Castrol Jaguar team, usually with Denmark’s John Nielsen. More wins and podiums followed. In all, Cobb's career spanned 21 years and included co-driving the victorious Tom Walkinshaw Jaguar with Nielsen and Martin Brundle at the 1990 24 Hours of Le Mans, joining the shortlist of Americans with overall wins at the Sarthe. Cobb was World Porsche Cup champion in 1994. Since retiring from driving, Cobb has turned to team management, where he’s discovered/mentored rising stars like Joe Gibbs wheelman Brad Coleman and 2016 Porsche GT3 Cup USA champ Jesse Lazare.
