Suggested

Increased amount of sponsors

So, in the F1 Codemasters series of games, you can either play MyDriver or MyTeam. You can’t really customize such cars, nor can you customize iGP cars very much. That’s why the Modding community developed Modular Mods, which allow for the player to use real company logos.

I’m not quite suggesting this (it may be illegal, IDK), but I would like more varying sponsors.

I'd like to be sponsored my Gene Haas.. he seems to have a lot of money to fix his race cars. 

Having the car decked out in sponsorship would be nice, i think actual real life sponsors would have to be onboard to avoid the legal ramifications but they would also require an audience i imagine.  iRacing is an actual company anyway. WTF1 is basically an online business too.
