Racing Game Physics
T = X + (Y * S)
Where T is the stabilizing force on the car, S is the amount of slippage, and X and Y are two of the car's stats (probably measured in G's). This formula would be applied to each tire separately to account for the suspension.
NOTE: The thing that might not be obvious here is that the car doesn't slip at all as long as X isn't exceeded.
What do you think of this?
