This mod improves the behavior of the air seat suspension in ETS2, making the driver’s movements feel as realistic as possible:
Smooth motion over bumps and uneven roads
Natural response to tilts, turns, braking, and acceleration
Minimal jerks at low speeds and during parking

Important:
Physical camera must be enabled
“Amplitude” set to 155
“Camera horizon lock” set to 10

Recommended: “Bump simulation” set from 105 to 115
Tested on ETS2 version 1.57 and 1.58

v2.1
Improved and balanced forward/backward movement.
Adjusted camera oscillation damping.

Note: Seat suspension affects the first-person camera for a true-to-life driving experience.
