Following the Indy 500, the #90 PREMA car driven home in P12 by Callum Ilott was found in breach of the technical regulations due to a front wing endplate not meeting the minimum height. As a consequence, the team was disqualified from the race and received accessory sanctions.
While the same wing was completely original, successfully passed tech multiple times throughout the month, and the issue didn't lead to any performance gain, the car ended up being non compliant with the rules at the end of the race, so the team accepts full responsibility.
The team is currently investigating the root of the problem, which can involve incidents and fitment or production issues. We look forward to implementing the needed procedures to ensure improved control and avoid these kinds of issues in the future.
