Good article in
Racecar Engineering on BoP in GTD. Mainly on IMSA, but talks about differences with FIA.
A few takeaways:
Macau, WEC and IMSA share data to help each other although the BoP process is different (no torque sensors in IMSA, still air restrictors) and there are some key differences between the series which mean they aren’t directly relevant to each other.
Torque sensors and IMSA specific testing at Windshear might come in the future, but it sounds like costs are a reason why this is not done at the moment.
The IMSA controlled test sounded interesting. Parc ferme conditions all the time. Teams told the fuel and tires and ride height, wing setting etc… to remove gaming the system. They don’t have long to go through all the data. The article talks about this a lot. New cars are always a challenge to BoP.

Worth remembering and is pretty fundamental to what BoP actually is.
They are worried about different tracks. Daytona, Sebring to start doesn’t help! As before Daytona gets some extra aero restrictions because of the impact of drag there.
