Greg@Challenge, if you see this post, my car arrives in 3 weeks. Surprise me if you can
no problem. but i must say the DD diffusor looks really good....

funny thing what DD wrote on her blog about the diffusor:

"The M3 diffuser has two fins that extend from the rear bumper to smooth and channel airflow from under the car into the low pressure area behind your vehicle as it moves at higher speeds. In concert with our aerodynamic components, our diffuser results in more stability and higher speeds and cooling effect to the rear differential."

this diffusor is for nothing, just for look.
