Being on the other side of the pond and never being able to participate
I can still throw in suggestions.
In the discussions about classes I don't see anyone mentioning enginetype. I think you must divide between forced induction and normal aspiration. That is pretty easy to decide upon and then you can leave the rest. All our cars are basically built pretty much the same in other aspects.
You can't have to many classes this is just about who has the fastest car, right? And that is me
