3d printer - heated bed version 2.5

After the bed-holder (made of 8mm acrylic) warped like hell under the 90°C of my heated bed version 2, I now replaced it with wood.
I did not print yet as I´m still investigating why the center is 0.35mm higher then the edges.

Is it possible that the bed is actually flat?
Perhaps the steel guide rods are sagging 0.35 mm down in the middle?

They are not.
You are talking about M8 steel bars, less then a meter in length.
Not about rubber bands.
