I decided to make a version of my air suspension and apply it to the Vivace. I would like to thank @Blijo and @OverPower for their mods as I used them to figure some of the ins and outs of the input_actions and also how to set the suspension up so it wasn't the same consistency as a water bed.
This mod contains Air Struts in the front, and Air Springs and Air Shocks in the rear. These parts only work on the wide suspension for the front and rear. There is no pre-made configuration.
Anyways, this mod is meant mainly to slam the car, but has many purposes such as supporting heavy loads.
These are the vehicle controls. Y and G reset the front and back of the vehicle to a predetermined middle height, respectively. The Ctrl and Shift variants of those progressively lower and raise the front and back.
To get the correct ride height and suspension stiffness, it required me to essentially pre-load the suspension. This makes a breaking noise as you spawn in which always happens. It only occurs once.
