the 1955 (maybe 60) truck (tiny one) doesn't work with the rear suspension set at pushrods, multilink, and the macpherson struts. That's as in depth as i've gone, but for FWD minitrucks, these three, at the very least, are not functional rear suspensions. (discovered making an ultralight 598 pound minitruck (271.248 kg) which now has to be boosted to sub 650 pounds )
I'm not smart enough to figure out how to deal with disappearing suspension components. Engine RPM and power is what i'm good at. Starting to improve on turbos.
Maybe it was the game restiction, so players cant use these suspension in that kind of body type?. You can ask automation devs for troubleshoting.
