Wow, thanks, it's finally staying on ground! I messed around settings so that it's wheels are touching ground and spinning same direction. But car feels way too light, is there way increase its weight or increase gravity? It's like driving on moon.
But there is more problems, one is that when turning only left side wheels turn.(I have set wheel locations correctly) And another problem is that car is moving very slowly, maybe car body is touching ground? Could you check that if your debug is working and maybe send a screenshot?
Here is one question I really need answer when I'm building another vehicle:
So when im modelling vehicle should I move all wheels to center of modelling program to get their pivot points correct, and then move them in place inside DBP by using offset limb?
I think you have to download modified model to test my code because now I put all wheels to center of 3ds max and moved wheels to their place with code in DB:

Here is code with my settings(I added mouse controlled camera for better testing):
