You better be able to sport some exceptionally large front air dams and side sills, for I find it ridiculous that so far, putting merely a rear wing on the car gives you magical control of front and rear lift. The fulcrum effect would actually increase lift on the front axle if this were the case. Cars that have aerodynamic downforce, should look the part. You cannot achieve those levels of downforce, then look at what appears to be a relatively stock vehicle. Its a small detail really, but I enjoy this game for how realistic it is and I think this is certainly an area for improvement. Also, they should include static weight distribution as part of the statistics so that you can easily balance the downforce coefficients, and not spend so much time just guessing and checking. That's what I think, so uhh, yeah.
It would be great also if there was a limited number of ducting options for the cars. This would naturally increase drag, but would address issues of brake fade and engine heat (two factors not currently in the games but should be) which, with engines making almost 1000 horsepower, is definitely a real life concern. While I'm on the subject, the brake upgrade would only make the brakes slightly more powerful. Where they would really shine is in their fade-resisting capabilities, something hard to appreciate in a game with no fade at all.
