Let me update my post. It doesn't matter if the robot is square but the wheels should be equal distances from each other.

Our test wheelbase was inadvertently square and drove fine. Our final bot was rectangular and had an extremal difficult time rotating. The weight load was similar to our test platform, also WPI had a square robot 2005, and a few other teams with holonomic drives had square robots. None had no problem rotating, leading us to conclude the squareness of the robot effects the rotational ability.

I would recommend making sure you load the system with at least 140lbs throughly testing it before you commit. Rotation is a big part of this drive system.
