Hey everyone,
I'm excited to share my physics mod for American Truck Simulator!
This mod introduces:
Enhanced suspension dynamics: More realistic bounces, roll, and weight transfer.
Improved tire grip and friction: Traction based on road conditions.
Realistic braking behavior: Gradual deceleration for loaded and unloaded trucks.
Authentic cab movement: Feel every bump and curve when you're behind the wheel!
Changelog:
v1.0 - Initial release
v1.1 - Reworked cabin suspension behavior
- Improved brakes feel
- Adjusted 5th wheel angles
- Matched real-world turning radius
- Improved gearbox behavior (clutch feel)
- Added compatibility with 1.55
v1.2 - Adjusted 5th wheel pitch and roll to JOST standards
- Tweaked trailer pitch and roll based on available trailer kingpin data
- Adjusted tire grip based on Michelin X-Line 295/75/R22.5 data
- Cabin pitch and roll angles matching real-world counterparts
- Increased air resistance to better simulate Class 8 American semi-trucks
v1.3 - Adjusted brake torque to DOT‑compliant stopping distance
- Slight adjustment to cabin suspension damping
- Tweaked truck and trailer suspension damping to better match Class 8 semi-trucks
- Transmission and Clutch viscosity adjusted based on Eaton/Detroit publicly available data
v1.4 - Brake bias adjusted
- Suspension damping modified to better match behavior shown in tests
- Flywheel tweaked to make the truck feel heavy (no more car-like behavior)
- Tweaked force feedback configuration
Here are the settings used in testing:
Truck stability - 12%
Trailer stability - 0%
Cabin suspension stiffness - 50%
Suspension stiffness - 35%
Driveshaft torque - 37%
Braking intensity - 72%

Installation: Drop the mod file into your ATS mod folder and enable it in the Mod Manager.
Feedback: Let me know how it works for you! Feel free to share your thoughts or suggestions for further improvements.
Let’s hit the road and enjoy a smoother, more authentic trucking experience!

Re: Truck Physics [1.54]
How come there is no feedback on this one?
