ETS2 1.58 – Improved Truck Physics

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{3dbc7e37233219ad86c09449b2e76c97f09c3a7547c91a72b55e5f0ace30e79e}
