WeatherTech Raceway Laguna Seca in Monterey, California, will host round four of the IMSA WeatherTech SportsCar Championship on Sunday, May 11. The Porsche factory squad will field two 659-PS Porsche 963 hybrid prototypes in the top GTP category, while customer team JDC-Miller MotorSports will enter a third 963 chassis under its own banner. In GT competition, Porsche Penske Motorsport will run two 911 GT3 R cars—one in GTD Pro and one in GTD—with AO Racing substituting its usual green “Rexy” livery for a pink “Roxy” machine in GTD Pro, and Wright Motorsports campaigning an identical 911 in GTD.
Porsche currently leads all IMSA standings after victories at the Rolex 24 at Daytona, the 12 Hours of Sebring and the Long Beach sprint race. In the No. 7 factory 963, Felipe Nasr and Nick Tandy have won each of the first three events; their teammates Matt Campbell and Mathieu Jaminet aim for their first triumph of the season in the No. 6 entry. Customer team JDC-Miller’s No. 85 car will be driven by Gianmaria Bruni and Tijmen van der Helm.

In GTD Pro, AO Racing’s “Roxy” will be piloted by former Porsche juniors Laurin Heinrich and Klaus Bachler. Wright Motorsports’ No. 120 911 GT3 R will feature California natives Adam Adelson and Elliott Skeer in the GTD class.
Laguna Seca’s 2.258-mile circuit includes 11 turns and the renowned “Corkscrew” drop, where high tire wear and wind-blown sand demand strategic setup and pit-stop execution. Porsche Cars North America was recently named the track’s official car partner and will introduce a Porsche Driving Center at the venue in 2026.
Porsche Penske Motorsport will simultaneously contest two FIA World Endurance Championship rounds at Spa-Francorchamps, making this weekend a rare transatlantic double for the marque.
