they sure did work on the aerodynamic factor on this race car. I wonder if they put as much effort into it's other racing factors, like fuel, induction, or braking systems?

I think it would be accurate to say that a lot of work went into the aero on this race car, but nothing close to that mush work went into it's brakes, or fuel system, etc. 

Just pointing out how much work went into the aero, and not very much into the other systems, but I'm only guessing.
