That kind of depends on what you did at the front, and the shape of the rear. I would like to hear others' thoughts on this.

I have read repeatedly on here that only minimal improvements to aerodynamics can be achieved with the front, while the greatest difference can be had through the back. Grill blocks and air dams work. People think that nosecones will make a car more aerodynamic. They just make things worse in a cross-wind. A Kamm-back or better yet a boat-tail will allow the air to stay attached longer, leave a smaller wake, resulting in less drag.
