It was a day of milestones for Porsche and Penske at WeatherTech Raceway Laguna Seca.

The victory for Mathieu Jam inet and Nick Tandy in the No. 6 Porsche Penske Motorsport Porsche 963 was the 600th victory in IMSA competition for Porsche, and was followed seconds later by the 601st as AO Racing won GTD PRO in the No. 77 911 GT3 R with Seb Priaulx and Laurin Heinrich. The milestone victories occurred, rather fittingly, at the track where the sports car manufacturer held its celebration of its history, Rennsport Reunion 6, a few months ago. It came on the heels of a World Endurance Championship win for the Hertz JOTA Porsche 963, the first privateer Hypercar victory, at the 6 Hours of Spa-Francorchamps the day before.
