Pawn following navmeshpath centered?

Hello. Short question here.

I made a Navmesh and setup a Target Point and a Spawn Point. This is for a TowerDef game.

I spawn the mobs and they follow the path correctly. However i want them to stay centered in the navmesh. At the moment they kinda behave like racing cars. Instead of taking the shortest way i want them to keep centered. They stil should take the curves smooth and not snap.
