If lower arm is longer, it is OK, and pretty often used in real cars. It would be nice to have for those rims some tires, which are narrow as those rims, but as high as those ballon tires. Most probalbly there are some 3rd party tires.   Somohow ahppned, that I put in scaler those 7.8 stud tires (used in Arocs and others). First thought was, that normal suspension wont fit in width of 18 studs. But that cosideration was based on using those big hubs. But then I took thse out of drawer  and and now I howe sotnig like front part of Ariel Nomad in scale of those tires sorry
