Max Angelelli put Wayne Taylor Racing on top of the timesheets during Thursday night practice ahead of this weekend's Rolex 24 at Daytona International Speedway.
The 50-yer-old Italian, who is making his final professional race apperance at the 55th Rolex 24, posted a 1:37.757 time behind the wheel of the #10 Wayne Taylor Racing Cadillac DPi V.R.
Angelelli will share the car with Ricky Taylor, Jordan Taylor and Jeff Gordon during the race, which marks the opening round of the IMSA WeatherTech Sportscar Championship.
It was an eventful session for the #10 car, with Gordon triggering a brief red flag period for a spin before Angelelli took over to set the fastest lap.
Second quickest during the 90 minute twilight run was Filipe Albuquerque, who brought the pole-sitting #5 Action Express Racing Cadillac DPi to within 0.148 seconds of the WTR machine.
