@NuvolarixDRS will not be different between cars by how i know Codemasters.. RB wont be the super OP car either, they might end up being a little faster but they also never made Merc that 1 second per lap faster when they were..
Id expect the car to always be the same setup wise no matter if low downforce track of high downforce especially as the suspension was almost always the same anyway
Although i might sound negative so far and am actually not sure if i will buy as dirty air length and tyre temps for AI seem unchanged i will say, its hard to resist the much better handling and more detailed setup, looks really good on that front!
