I completed the final version of the chassis after many minor repairs and spring redesigns. The suspension system will be fitted with the finished casing and interior.Its features include:It is very rare to set up the front and back six bar linkage.There is a large adjustable range of air suspension.The combination of main and secondary springs can adjust the hardness of the suspension system.(I recommend that players who start high physical computing remove the inner dip.)The disadvantages of this:1. The current training may be hard and not comfortable enough.2. The shell is not loaded, and it differs greatly from the final version on the resistance coefficient.My evaluation of it: a slightly hard suspension system, which is more suitable for a coupe than a luxury car. But in the grip of the wheel, it seems to me to be flawless (if the game's low-physics calculation doesn't require a strange algorithm to make the tires fan out)[] PS: its zoom ratio is 1:0.321.Furthermore, it is welcome to build new vehicles on its basis.
