   Hey. I have created this tool for guys who messing around game's vehicle physic settings. It provides you interface where you can modify car wheels, suspension and pacejka in real time and see the changes immediately.
   
   
   
   I also implemented saving and loading setup files, so you will be able to exchange them together, or just save your own creations.
   Saved settings will be stored in [Game dir]\maps\Addon_Maps\Physic_Lab
   
   How to install: Copy code below and save is as Physic_Lab_Track.java file in [Game dir]\maps\Addon_Maps\Physic_Lab\scripts\src directory. Yes, you need MWM already installed to do that.
   
   Then just run the game and go to the Physics Lab track.
   
   This tool is just for tests and experiments to obtain knowledge about meaning of setup parameters. It is not game editor. If you don't know what to do with it then don't use it.
   
   The code:

2. Forza Studio
   Sections: Downloads \ Other files
   Tags: .net, Application, C#, Extraction, Forza, Open Source, Tool, Utility, Visual Studios, Xbox

   
   
   Features
   Forza Studio 4.0 now officially supports the viewing and extraction of most cars (.carbin), wheels, brakes, rotors, calipers, tracks (.rmb.bin), and textures (.xds, .bix) from both versions of Forza 3 and Forza 4.
   
   Controls
   Its use is fairly straightforward in my opinion. Right-clicking various sections will bring up a context menu specific to that control. When viewing a model in the viewport, use the WASD keys on your keyboard to move the camera position and IJKL to look around. I’ve also included zip extraction functionality that can be found under the utilities menu for those who wish to use it instead of the usual QuickBMS script.
   
   Requirements
   .NET Framework 2.0 (or greater)
   XNA Framework 3.1 (4.0 is different)
