Definitely make sure the underbody is smooth, and that it stays smooth all the way to the tail. A diffuser would do better than a rear wing for low-drag downforce.

Since you'll be running with slicks, tread induced drag won't be much of a concern, but it might be a good idea to add some tire spats.
