Help On Understanding Scripted Suspension

So I have been trying to figure out how to make a working scripted suspension. So I have read some articles and they suggested that I go and have look at the Jeep found in the suburban map made my roblox (you can find it by going on the tab when you first open roblox studio, then click suburban). I don’t really understand how the different formulas work to calculate the suspension. I also don’t understand what the part “Thruster” does.

Overall could someone please go over how to code works step by step? Sorry if I was a bit broad on this question. Anyways, thank you so much if you can get to me :grin:
