If you go to http://www.geocities.com/MotorCity/Shop/1911/ and let the page fully load you will see the animated GIF at the very top center of the page. The rear apron helps in the aerodynamics of the vehicle by keeping the air stream low. This helps at higher speeds to keep the butt down and aides in reducing drag (kind of hard to explain without going into physics and diagrams and such). It also reduces the debris from collecting up on the hatch and, especially, the window -- my experiences with oil spray from my previous case have proved this :( John J. shared some generic aerodynamic papers with me about this stuff and I confirmed some of it with my experiences. One of these days I would like to make a new, detachable apron. It is nice to have it missing when working on the engine.
