99 GAINSCO Auto Insurance Chevrolet-powered Riley, driven by Alex Gurney and Jon Fogarty.

Initially, the team's owner and founder, SCCA Formula Atlantic national champion and GAINSCO executive Bob Stallings, drove No.

In 2006, with hopes of his team reaching its "championship potential", Stallings decided, two races into the season, to "step out of the cockpit", signing Jon Fogarty as his full-time replacement.

Eventually, their victory at Sonoma gave them a one-point advantage over Pruett and three markers over Max Angelelli.

In the Sunchaser 1000k season finale, Alex Gurney and Jon Fogarty rallied to finish eighth after a series of mishaps and claim GAINSCO/Bob Stallings Racing's first Rolex championship.
