i was wondering what race teams are using to keep turbulent air flow that is uner the car, attached to smooth underbodies of race cars, especially for the rear diffuser, since the prolonged attachment of airflow to a rear diffuser would suck the car down better than if the air seperated sooner, what shapes or anything is used for this?
thanks!

RE: Underbody Vortex Generators..
Carroll Smith suggested the use of vortex generators to keep flow attached on the under side of high angle of attack wings and in ground effects tunnnels.
To me, in theory it makes sense that it would work.

If it is occuring, one thing that will help is adding or adjusting a rear spoiler or a wing.... as it works together with the diffuser.
Here is some reading on the subject:

No, they're not for traction. Dimples delay flow separation. Do a google search and you'll find lots of discussion.
