Hey sry djey i was just surprise since every other molecule of the game has been decrypted so why not this one since its very important. Tire physics tells everything about the grip to the road. This isn't an arcade physics at all and i can prove it to you if you want. It was made to feel arcade to sell copies but the underlying engine comes from ISImotor2 which powers titles like rfactor and gtr2. Sebastian Tixier who was the lead physics guy knew what he was doing and i praise him for that despite wether or not he was the original author he atleast made sure the future gamers had the best possible experience on open roads as they could ever possibly get. I will look into zmodeler then. So you are saying camber physics are dependent on 3d dummies? It's not a text editing parameter? In rfactor you set the camber angle using a notepad and it looks like this : 

 
CamberRange=(-2.0, 0.5, 1) Camber in degrees.
CamberSetting=0
The Z06 is an original car in the game. Will changing dummy angle affect physics or is it just visual change? I am only looking to change the physics so if it's just visual i won't bother.

I am not trying to make a ridiculous camber rather correct the existing cars to a factory standard physics as well as camber. How is TDUF different from TDUPE?

For example the z06 coupe has alot of camber on both front and rear wheels when it should have very little and makes it look odd but i dont know about the physics...
 
Did you also know the physics are mostly from ISI game? I saw the sound files description had GTR2 in them and the tire physics are Pacejka tire physics which is same as ISI. It's essentially a slip curve tables. Why hasn't anyone decrypted them already? I talk about the "tire1.bpjka" inside physics-tires.
 

 
Here is a pacejka tire file from rfactor 1:

Hey guys the only reason i am trying to perfect the physics of tdu 1 is because of map free roam and size. Is it possible to edit the camber(wheel angle) of the cars somehow? Maybe using hex if tool not possible? Thanks!
