If you can catch the air off the tire and force it straight back, air is much more linear under the center & out the back.
This is apparently correct. Google exhaust blown diffuser. Some F1 teams route the exhaust to push the air past the inside of the rear tire, creating a boundary layer and preventing the air washed off the tire from getting pushed into the diffuser.

Anyway, I would also be interested in a functional diffuser if the Trackspec guy moves forward. Although with a small bench brake, fabricating one doesn't look that difficult.
