The Cadillac DPi-V.Rs have had 15 kilograms added for the Detroit race this weekend, whereas at Mid-Ohio the cars ran 10kg lighter than they had at Laguna Seca. Van der Zande, who shares the #01 Chip Ganassi Racing Cadillac with Sebastien Bourdais, said it was time for IMSA to make the BoP changes track-specific.
“The last street track was in Long Beach and we did very well, especially Sebastien had a race that was amazing,” said the 36-year-old Dutch ace. “I think we’re going confident into the second street race of the year. I think the Cadillac has always been doing well at Detroit.
