There’s a hotfix being deployed tomorrow at 14:00. I suggest going to https://members.iracing.com/download/member/home.jsp and download all the cars, even the ones you don’t own. That way when the service goes down for deployment of the hotfix you can use Test Drive to test both cars. You can access Test Drive from https://testdrive.iracing.com/login.html. It does require registering when it is active but that is straightforward.
I prefer the Dallara F3 to the PM. It is a newer car with NTM7 and full damage.
