At the moment, only the Mercedes AMG One has a Race Mode toggle available (as far as I am aware) to activate and deactivate the aero/raise and lower the car ride height. Many cars already in FH5 have cruise and race modes in real life and it would be brilliant to be able to use these modes in game just like with the AMG One. The two most obvious cars that could benefit from this addition are the 2013 McLaren P1 and the 2017 Ford GT.
I think adding the race mode feature that’s on the amg project one to more cars would be really cool. i.e.: add race mode to the mclaren P1
