You can find the person you got the model from if you look in the toolbox for the same model.
It’s very tough for us to try and help you with almost no information supplied other than a couple pictures.
Did you get the whole model from the toolbox, or just the chassis and add your own body?
I’d suggest looking to see if the wheels are colliding with the body, or aren’t aligned properly.
If you go into the Settings in Studio you can click on a tool called “Show Collisions” (or something similar, I’m not in Studio at the moment) and it will show a red ball where every collision is occurring in Studio test sessions.
