Does that mean we can still move the upper structure down by 200mm eventho we don't move both structures rearward? It is the "then" that bothers me.
Good call, I need to change this wording so that the rearward movement and downward movement aren't linked together like they are.
Regarding the diffuser I think it will be fairly big COMPARED TO LMP1 cars of those days, but do we want to have identical cars? I think it is good to see relatively big diffusers, rather than the cheap ones we see in F1.
I am however still a bit confused about the Surface A thing because of "the area specified by the rear bodywork height template and the flat floor template". Could you define this area a bit better? Is it viewed from above? Then it doesn't make sense because the height template and the floor template almost not overlap. This is how I understand it: "Surface A is the surface formed by any bodywork visible from below, covering the area of the rear bodywork height template. Surface A may not contain any holes and must be no more than 360mm above the reference plane."
Again English is not my native language to pardon me if I make less sense than what you wrote in the rule book!
If you view these templates from below, the rear edge of the flat floor template lines up with the front edge of the rear bodywork height template. It's the entire area formed by theses two templates viewed from below that is used for this rule. Surface A is then whatever bodywork is visibile from below within this 2D area.
There might be some confusion caused by the fact that the rear bodywork height template is offset in Z, but for this rule you should ignore the Z position of the templates, we're only interested in the 2D outline they form when viewed from below. Would it help if we included a separate template for this?
If we didn't include the flat floor template in this rule like you wrote, then there would be a possibility to have a slot in the floor right at the junction between the floor and the start of the diffuser.

Agreed there is not enought space for the wheels to turn, however we chose to ignore this aspect to keep things simple. In absolute terms I think the dimensions of the front wheels are fairly realistic, if anything the rears could be a little wider, but we want to keep plenty of free space for the diffuser.
