Eazy Car Physics is a complete solution for GTA-like vehicle physics in Unity. Its modular design and strucure makes it easy to setup while still offering a wide range of advanced options, making it possible to achieve all kinds of vehicle physics.
Modules include the engine, gearbox, suspension, tires and brakes. Different preset modules can be created in the editor, and then used during run-time. Modules and components can also be swapped around during run-time. Moreover, components are dynamically affected by the environment and driving style.
Eazy Car Physics is still a work in progress.
