Petit Thursday Practice

The best race of the IMSA calendar. How is everyone settling in? Well probably very nicely in the campsites with some posh Bourbon, but here we will look at the less important team preparations.


GTD

Build-Up laps

Ferrari have completed the most laps and head the averages.

#12 Vasser Sullivan Lexus missed out on running fp2. While making up for it and setting fastest time in fp3 it received a driver through penalty for pit lane violation1. The fastest lap in the last session put it 0.25s off the fastest single lap of #47 Ferrari in all running.

Fastest Laps and Averages

Note: Total laps varies from chart above due to a different measurement point on the lap.
