So, after a few days I finally sat down to work on this for some hours. First of all, thank you everyone for being so interested on this project and for the good luck wishes. That certainly gives me an extra motivation :)
I decided to improve on that cockpit section, because honestly that one is very crude. I’m having trouble with rendering at the moment, so for now I’ll post the drawings here on wireframe view. Anyway, the first version I posted some days ago was really flat, I just joined the two bulkeads by flat planes. At first I wanted to make both the upper and lower surfaces a bit curved, but then I realized that the lower surface curvature beings from backwards of the dash bulkhead, so the lower surface is still flat. The upper surface is slightly curved, and that is more visible closer to the soon to be implemented cockpit opening :P
The regulations regarding this section of the cockpit talk more about extrenal and internal widths, and about how it must be symmetrical to the car’s centre line (as if that needed saying). Long story short, it states that the width at any point must not be less than it would be if the chassis simply taper forward linealy from the dash to the front bulkead. It also states that a minimum area must be left clear inside the cockpit (the template is inserted 10cm behind the forwardmost pedal), but I’m not worried about that because I’m not modelling the chassis with exact thickness
The measurements are much the same as from the first version I posted, except that the front bulkhead is now at its minium allowed size, 300x275mm. 550mm high at the (A), 600mm high at (B).
Here are some pictures:

Front bulkhead detail
Once I do the front suspension I’ll add a tiny bit of detail on the front bulkead: little round covers that give access to the torsion bars. However I’m doing that just for detail really, I’m not going to draw any of the internal suspension system.
Also, those vertical and horizontal lines on the cockpit body will be gone once I can sort out the rendering.
