So far the race has been terrific in all classes, but the prototypes have been the most interesting, to me, anyway.
DPI is the new GTP. IMSA is back.
Helio got punted by a GT car and lost a lap, but with three hours left he is only 30 sec back and closing. They have had some bad luck, but their program is off to a roaring start. You've got factory cars there from Cadillac and Nissan, but Penske has proven if you can execute with an off the shelf P2 car you can challenge for wins. It's not over yet, but the way Helio is closing in I suspect the Penske has plenty of time to get back up front, or at least make things more interesting.
Nearly as interesting is the Visit Florida car is currently second after a quiet day running just outside of the top five. They have not been in any fights or scraps and there is not a scratch on that car. I suspect they are playing the long game and waiting for the end to make a move.
