One problem with removing that noise encapsulation tray on a 500E is that it holds the fender liners in place-if you do not find another way to hold the liners in place, they'll get sucked into a wheel and destroyed.

I also think you'd be screwing with the airflow under the body, which is something as I understand is very carefully established.

I'm keeping mine in place, FWIW
