As normal they screwed the C7Rs as to BOP

The Mobil 1 Twelve Hours of Sebring is Saturday, March 16th. The green flag falls at 9:45 pm.

The IMSA WeatherTech Sportscar Championship is headed to Sebring International Raceway in a couple weeks for the second stop on the 2019 schedule,
but it will be the 1st race of the season that utilizes IMSA’s new season-long BoP.

IMSA has released the new Balance of Performance (BOP) tables this week which have been updated following the season finale from Petit Le Mans at Road Atlanta last October.
This will be the BOP used by the teams for the Sebring 12-hour race as there is no longer a sanctioned Sebring test day.

As for the changes in BOP for GTLM, Corvette Racing was the only team in the class with no updates.

The C7.Rs will race at 1240kg, air restrictors set for 31.5mm and will carry 92 liters of fuel.

Porsche and Ferrari both lose 10kg to come in at 1255kg while the Ford GTs gain 10kg which makes them the heaviest in GTLM at 1275kg.

Ford and Ferrari also pick up an extra liter of fuel and all three turbo cars (BMW, Ferrari, and Ford) have all had adjustments to their boost tables.
