Hej hej, I like where this is going!
I like the fact that you are opting for a peaky N/A screamer with smooth torque and power development through the rev range. Seems to make a lot more sense for a light, compact MR chassis. Also digging the roof scoop BTW!
Regarding the front, I attached an image showing a few things that I had in mind then and now. I hope it's understandable what my mesh-like sketching is trying to illustrate. I think the original design has its headlights as far inside the front/fender area as possible, so it wouldn't make sense to move them, from my understanding. My suggestion was merely a sort of cover or fairing, obviously transparent, to take the edge off, aerodynamically speaking.
However for the brake ducts, you probably want the opposite. Trying to blend an air intake into the shape of the body work creates much more turbulent airflow, than if you have that intake properly stick out. A good example are sub-sonic warbirds: Take a look at german WWII aircraft engine intakes, or the P-51 Mustang's under-belly radiator scoop. I guess for the Raceabout you could leave the stock design and simply take out the lower headlight units to use the remaining pipe shape. The one I drew up would be an alternative, somewhat hybrid version.
Lastly, and I really don't know enough about racecar aero to judge whether it'd be warranted, but anyways I increased the area of the canards. More importantly, the leading edge doesn't fade into them, instead it's perpendicular to the airflow, which is always the most efficient solution for sub-sonic airflow and a given surface area. Efficiency could be further increased with a "fence" on the outer edge, but that might hit polygon count too hard for something that is, for the game's purposes, just a cosmetic detail.
So there you go, more nitpicky fussing about from me.
