Improved Truck Physics for v1.58
Truck Physics Improvement mod for immersive gameplay
This mod brings a more natural “bouncy” feel to the cabin and adjusts the chassis suspension to better simulate the weight and inertia of a heavy truck. Expect more realistic nodding, rolling, and overall smoother suspension travel.

Key Changes:
Enhanced Cabin Dynamics:
Maximum pitch angles (front/rear and roll) have been adjusted to more realistic values, providing natural “nodding”.
Softer cabin suspension with increased travel and reduced damping for a smoother, less “plastic” feel.
Significantly reduced cabin sway bar factor, allowing for more natural lateral movement.

Reworked Chassis Suspension:
Reduced damping for both truck and trailer axles, making the suspension more reactive to road bumps.
Lowered sway bar stiffness to allow for more realistic frame roll during cornering.

Drivetrain & Inertia:
Increased flywheel inertia for more realistic engine RPM behavior and smoother power delivery.

IMPORTANT:
“Physical camera movement” must be enabled
“Physical camera movement factor” set to 200%
“Interior camera horizon locking factor” set to 0%
“Uneven surface simulation” set to 130%
Cabin stiffness – 0% (Softer) – 20% (Harder)
Suspension stiffness – 0% (Softer) – 20% (Harder)
Truck and trailer Stabilization – 0%
Braking intensity – 50%
Torque resonance – 100%
Steering sensitivity: 0.31 (0.31-0.33 Tolerance) (for keyboard)
Steering non-linearity: 1.75 (for keyboard)
Steering animation range: 1380° (for keyboard)

Give this mod hight priority
If you’re not sure about the suspension stiffness, here’s what I recommend:

For older truck models:
Cabin stiffness – 0% Suspension stiffness – 0%
Or
Cabin stiffness – 10% Suspension stiffness 0%
For modern truck models:
Cabin stiffness – 20% Suspension stiffness – 10%
Or
Cabin stiffness – 20% Suspension stiffness – 20%
