“Night practice was fun,” said Braun, who has been a Rolex 24 regular since competing at age 16 in 2005. “This place at night, with the traffic and the speeds in a Prototype car brings me back to having a lot of fun in the old Grand-Am DP days.
“The test is going great. ORECA has been fast right off the bat, and having Romain [Dumas] and Loic [Duval] have been a great asset, because they know the car well. We’ve been going through our program, and we’re very happy.”
