Corvette Racing entered a Chevrolet Corvette C7.R with Tommy Milner and Wayne Taylor Racing's Jordan Taylor and Ricky Taylor competing in the company's first World Endurance Championship (WEC) race outside of the 24 Hours of Le Mans. James Calado missed Le Mans because he suffered from two brain haemorrhages as a consequence of a heavy practice accident. He did recover sufficiently to return to sports car racing and retook his role of sharing the No. 71 Ferrari 458 Italia with Davide Rigon at the 6 Hours of Circuit of the Americas. Krohn Racing, who competed full-time in the 2012 and 2013 seasons, entered its No. 57 Ferrari 458 Italia for owner Tracy Krohn, his long-time teammate Niclas Jönsson and experienced racer Ben Collins. Matthieu Vaxivière returned to compete for Prospeed Competition after braking his vertebrae in a Formula Renault 3.5 Series accident in Monaco which forced him to miss Le Mans. He co-drove the Dempsey-Proton Racing Porsche 911 RSR. Enzo Potolicchio stopped driving for the rest of the season and his place in the 8 Star Motorsports Ferrari was taken by 24 Hours of Daytona class winner Jeff Segal. Nicki Thiim was absent because of a Porsche Carrera Cup Germany commitment at the Sachsenring and was substituted by Richie Stanaway.
