The Acura ARX-06 team of Meyer Shank Racing will arrive at the Sebring Twelve Hour a full 200 team and driver points lighter and without engineer Ryan McCarthy due to the manipulation of tire pressure data during the team’s Rolex 24 at Daytona victory.

The loss of points drops the No. 60 Meyer Shank Racing w/Cup Agajanian entry from first to ninth in the IMSA WeatherTech SportsCar Championship GTP standings. The No. 1o Konica Minolta Acura ARX-06—runner-up at the Rolex—now leads the team standings with 350 points. The No. 60 of MSR sits at 185 points.

The discovery was made by Honda Performance Development and reported to IMSA, which issued the points penalties and suspended McCarthy indefinitely. Michelin issues minimum tire pressures for safety reasons, which are monitored throughout the race. The MSR Acura ran with tires below minimum pressures, which can reduce lap times, but that did not show in the data sent to Michelin and IMSA during the race.

Meyer Shank’s Acura led 365 laps, including the first 62 and last 97. The closest competitor in terms of laps led was the No. 01 Cadillac of Chip Ganassi Racing, which led 198 laps.

The MSR team issued a statement apologizing for breaking the rules and accepted the penalties. “We do not want this error to overshadow the tremendous effort that our team, drivers and all of our partners have put forth to develop this new LMDh car. We consider this matter closed and are fully focused on resetting and coming back for the Twelve Hours of Sebring.”

The penalties were as follows:

• Loss of 200 team and driver IMSA WeatherTech SportsCar Championship points.

• Loss of all team and driver IMSA Michelin Endurance Cup points.

• Loss of race prize money.

• Team receives a $50,000 fine.

• Team and Entrant representative Mike Shank placed on probation through June 30, 2023.

• Revocation of IMSA annual credential and indefinite suspension of IMSA membership for team engineer Ryan McCarthy.
