There is no way to keep a car to the ground at that speed on something different from a salt lake bed, even in the simulation. If you are to accept completely illogical stuff happening, there is no meaning to use a simulator engine for such races. One thing is to allow modding to some extent, but in the realm of "it could be done". One thing is to race with a car that pretend to have 4000 Hp, 50 Kg of mass, no fuel consumption, 400 tons of wingload, no airdrag. There are already games that would allow such kind of stuff. What is the purpose to race on a track with a wheeled vehicle when with those performance you can fly?
