@@iDiOt5 it might be equipped with leaf springs in the back

I made my own physics mod which reduces the damping of the suspension and I also increased the mass of the cabin. The in-game settings are basicaly suspension as soft as possible and truck stability about 30%. This is the physics.sii SiiNunit { physics_data: .phdata { # Several changes have been made in v1.33: # - Suspension springing linearity curves recalibrated and made slightly progressive to simulate air springs # - Chassis suspension damping linearity curve recalibrated to simulate different compression and rebound behaviour # - Chassis suspension travel and working point recalibrated to mimic actual real-life parameters # - Maximum steering lock increased slightly to calibrate trucks' turning circles # - Braking curve made more linear to better simulate actual braking behaviour at lower speeds # - Cabin suspension and damping reworked # - Cabin mass increased to 650kg for better simulation accuracy # - Wheel mass reduced for better accuracy # - Chassis suspension damping adjusted for better accuracy # - Trailer suspension reworked with resistant forces applied at the fifth wheel to replicate the effects of trailer chassis flex # v1.35 Changelog: # - 4-point truck cab suspension # - Increased cab mass to 700kg (~the average mass of different cabs with different heights) # - Overhaul of trailer/truck weight distribution algorithm # - Better/more realistic weight distribution for tandem axles to improve traction # - Realignment of tyre collisions with their models to ensure that trucks/trailers roll more accurately # - Several bug fixes # Further physics improvements are constantly in the works to improve the driving simulation in-game. version: 2 # These coeficients are used for computing autocentering wheel speed. # The faster vehicle moves and the more steering wheel is turned left or right # the higher autocentering speed is. # Given value of speed_coef is for 100km/h velocity (linear raise). # Given value of angle_coef is for maximum wheel turn (30degrees, linear raise). # Returning speed coeficient is computed by multiplication of both coeficients. # When result coeficient is 1, returning speed is exactly the same as full # turning speed.
