The fourth and final test session of the day gave teams a chance to provide their drivers with ample running in the dark, and in a building theme throughout Saturday, Action Express Racing’s No. 5 Corvette DP was fastest of all with a 1:39.310 posted by Sebastien Bourdais. The defending race winners also topped the third session.
The Frenchman was more than a half-second clear of Wayne Taylor Racing’s No. 10 Corvette DP (1:39.886), which moved ahead of the No. 02 Chip Ganassi Racing with Felix Sabates Riley-Ford EcoBoost DP (1:39.917). Fastest lap of the day belonged to WTR’s Jordan Taylor (1:39.181).
Aston Martin Racing’s No. 98 V8 Vantage led GTLM again (1:44.480) with Pedro Lamy at the wheel, and held a notable gap over the No. 4 Corvette C7.R (1:44.799) and the sister No. 3 Corvette (1:44.992) to complete the top-3.

With rain in the forecast on Sunday, and having witnessed a litany of crashes and red flags, there’s a general sense that departing a day early might be the smartest call to make with the race two weeks away. Many teams have either decided to start packing up, others are waiting to see if rain comes, while others plan to run regardless of conditions.
