So, when I was modifing a car mod to make it have lowrider hydraulics I noticed that to make it happen I had to add 4 items on the carcols.meta and one comand line and a flag on vehicle.meta, on the mod car I manage to make it work but when I tried on a vanilla gta car I did all the exact same things and it did not work, even when I deleted another flags the car still remained the same, anyone knows what I have to do to make it work?

Other changes on the vehicle.meta worked like changing the handling but the flags still the original ones, like the flag that gives air suspension to the hermes was still working even tho I deleted it.

is there a way to put a FLAG_HAS_LOWRIDER_HYDRAULICS in order to make a vanilla car a lowrider(ex: hermes)? I only manage to make this on modded cars but the vanilla ones aren't working, even when i delete one of the flags it still works on the car.
