I was thinking about how I can make the car get a better grip on the road. My first thought was to increase the empty weight. But that cause the car to respond less and the stopping time increased a lot. I then thought about controling the MOI [moment of inertia] of the vehicle's yaw movement. BUt I feared it may make some strange things in the sim.

I then had a brainstorm. In real life, the car utilizes a special design on the chassie. In Formula 1 racing, this design is commonly known as the UNDERWORLD. This design directs the air underneath the car to increase in speed as the car accelerates. Do you remember the Bournolie Principle? As fluidic substance INcreases in speed, the preasure DEcreases. The underworld design creates this effect under the car so that the car will stick to the ground like glue.

I'm thinking about adding an imaginary wing [probably about a few square feet in size to be safe] with a negative incidence angle and located in the lower portion of the car.

Can it work? If it does, does it give the user more turning control?
