Grala youngest driver in Rolex 24 field: Being the youngest driver in the Rolex 24 At Daytona doesn’t phase Boston’s Kaz Grala-he’s done it before. Grala, who is halfway through his senior year of high school, will enter his second Rolex 24 next weekend as he rejoins Change Racing to drive the #16 Change Racing XBox Forza / Monster Energy / Orion Lamborghini HuracÃÂïÃÿÃýn GT3. Grala just turned 18, and has a history of record setting runs, having raced at the fabled Daytona International Speedway at just 15 years old as he competed in one of the lower tiered IMSA events. He finished a fighting fourth, and his record as youngest driver to compete in IMSA competition will likely stand for years to come as the age rules have since been changed. The Boston-based racer has been working to develop his NASCAR career, racing his way up the ladder from his local short track events during his summers. The 2017 season is going to be a big one for Grala, as he’s set to race in the NASCAR Camping World Truck Series.(Sunday Group Management)(1-20-2017)
