i think it really depends on how complex you want it to be, atm the ue4 wheeled vehicle code only supports 4 wheels so it you want to make a big 8 wheeler truck your going to have problems and would have to find other solutions
afaik though the code (physicX) includes variables for parts of the steering geometry (Ackermans princeple) i don’t know if it also has stuff for Castor+Camber / tow-in+toe-out, there’s a whole load of factors with vehicles and a whole load of maths
i could add that in most vehicles the suspention up damping if different to the down damping and you can also get spring with varied ratings depending on the distance they travel eg start soft then go harder the more they are compressed.
i think thats a bit much for most games but its up to you
