We are currently using the new 6" wheels in the kit, and using the spacing provided. While we turn, we don't maneuver/turn as well as we'd like to. FURTHERMORE, the main reason we're looking into this is because we want to move our wheels out a bit more so we have a bit more stability for the robot, thus making it even harder to turn, especially with the 4" AM plaction wheels we will be using as of tomorrow.

Officially, I can't say it's bad, since we didn't test on carpet. However, we tested on pretty slick concrete that may have been even easier than carpet, and that's what scared me. We will test on real carpet tomorrow.
