The atmosphere at Road Atlanta for the North American Road Racing Association’s second event of 2012 was electric. Over one hundred cars across four series, meant diverse fields and tough competition. Friday saw the running of NARRA’s first endurance race, the Road Atlanta GT90, while the weekend was packed full of action from rounds 3 and 4 of the US GT Championship and Whelen US TimeTrial Championship, as well as the SRT Viper Cup series.
