Former Star Mazda Champion and 2005 American Le Mans Series Rookie of the Year, Guy Cosmo, had his 24 Hour effort cut short by mechanical gremlins at this year's Grand-Am Series Rolex 24 at Daytona. Cosmo and the Blackforest team enjoyed brief success as teammate Alex Tagliani set the GT class' fastest time during practice earlier in the week. Unfortunately, the #15 Mustang Cobra GT suffered mechanical issues and was retired several hours into the race.
