Loek Hartog will make his Pirelli GT4 America debut, joining ACI Motorsports to team up with Dan Sibille.
The reigning Porsche Carrera Cup North America champion will pilot the No. 9 Porsche Cayman GT4 RS CS, starting at the season-opening round at Sonoma Raceway at March 28-30.
His co-driver Sibille has gained Porsche experience through various one-make competitions, most recently competing in Porsche Sprint Challenge North America.
Hartog, meanwhile, has built a strong record behind the wheel of Porsche machinery in recent years, but has notably never raced the German brand’s GT4 offering before.
“Dan and Loek are equally excited to join ACI Motorsports, especially given our recent successes in Pirelli GT4 America and our Pro-Am class championship in 2024,” said team CEO Curt Swearingin.
“With our expanded racing program, technical advancements, and increased competitiveness, we’re confident this partnership will elevate our 2025 campaign.”
Swearingin will himself defend his GT4 America Pro-Am title, teaming up with Porsche North America selected driver Riley Dickinson.
