Vehicle falls limp


I’ve been trying to set up my own vehicle for a while, and I’d say I’ve tried everything except probably the right approach. Exported several versions from Maya to solve some axis issues, set up the basic controls and wheels in the BP, linked the proper game mode and default pawn and set up the physics assets, but all I can seem to get is a limp car when simulating.

I’m definitely missing something, but have been banging my head for a long time, checking tutorials etc to see if others fall into the same trap, and nothing. Any clues, at least to know where to start investigating?

Thanks in advance
