Adjusting sidebar width on the home page

[EightWheels]

The right sidebar on the home page is significantly wider (and the left content area narrower) than all the remaining pages in the Corporate theme. I figured out how to narrow the right sidebar (and widen each of the columns in the left content area correspondingly); but I've only adjusted them about 10px so far. Is there a reason it is designed the way it is, and if I make the home page columns match the other pages width-wise, am I going to cause problems somewhere that I haven't thought about?

The themes seem so well thought out, I'm afraid to make significant design changes because I figure there must be a good reason it is the way it is. So before I really screw things up, should I leave well enough alone? It's not really a problem the way it is, it's just a cosmetic issue that I don't like to see that right sidebar "jumping around." LOL

The site I'm working on is http://bergey.net/host/ in case you want to take a look, but the demo theme shows the same issue.
