ATS - Ultra Realistic Truck Physics & Cabin Motion V1.4

Ultra Realistic Truck Physics & Cabin Motion mod for American Truck Simulator, created by Kass.

Fully supports all Trucks
Realistic suspension stiffness and damping — tuned for air-spring accuracy
Natural chassis sway, body roll, and realistic braking torque
Trailer flex physics via 5th wheel resistance and joint angle tuning
Enhanced cabin pitch, roll, and bounce behavior
Realistic wet road grip loss and braking curves
Adaptive steering for all controller types: keyboard, gamepad, steering wheels
Accurate wheel and cabin mass, clutch torque, and inertia values
Smooth at highway speeds, nuanced at low-speed turns, especially in cities and truck stops
Control Device Support
Keyboard: Linearized steering and damping with speed-based sensitivity
Gamepad: Dynamic responsiveness and center return
Steering Wheel (G29, G923, T300, CSL DD): Realistic force feedback balance and suspension feel
