You can easily tune every factor in the game's psyhical attributes, you just need to know how to make them, and ofc understand them. You can get about 80%+ realistic psyhics, but even though the game was made as an arcade game, not a as simulator, you can get some pretty good results. There are more factors that I haven't expected at all.
Just to avoid double posting.
Some from my last 2 Carbon mods:
