Re: rear diffuser

Yes you need that space to exhaust the heat from the center tunnel.

The reason a diffuser works is by creating a larger volume at the rear the air under the car rushes in to fill that void which speeds up the air under the car faster then the air over the car resulting in a vacuum.

It reduces drag by returning that air smoothly to the wake of the car reducing the size of the "bubble" thats otherwise also a vacuum trying to suck the car in the opposite direction of travel.
