I am thinking about picking up tires for the snow, but this is not a staggered setup.

Dunlop Graspic DS2 215/55/17 (all around)

will this mess up the VDC on my coupe???

 

It's not staggered but the overall diameter of the tires (front to back) are the same so the VDC shouldn't complain at all. The overall diameter of the tires in a factor staggered setup is pretty close to equal so the computer won't see a difference.
