Spacing between post content and widget cant be setted

Hi, I want to get a layout for my blog but I can do it using the Premiun addon of Layout and Spacing.

This is my blog:

I want to achieve this:

The logic say to me to do this:
On the Element spacing/content: get rid of the 40px on Right and Left

But when I do that, I lose the spacing between the post border and the widget. I want to maintain this spacing.
Look what I get:

Please tell me what I have to do in order to achieve what I want?

Thank you.
