So Right now I am at the Nurburgring with nothing going on since it is the off season. Since I am bored and ready to go home to Florida, I will upload some aero pics that I took. They will be from the BMW Museum in Munich, Mercedes and Porsche Museums in Stuttgart Germany.

Active Aero
Hope you guys like them, thats as much aero stuff as I can get out of all my pics

Most auto-x guys you see are running spoilers because thats all the street prepared or DP rules allow. My wing actually makes downforce below 45mph where the spoiler isnt noticable, make way more downforce at any other speed, and it makes less drag at all speeds than an SP spoiler. That corvette spoiler cost him about $70 for the piece of lexan and nearly $100 in fasteners. Yeah you can home depot something with luan and heavy steel **** from home depot for more like $60, but *** it will look like.

That is an airfoil. In the downforce orientation..
Interesting that that whole diffuser assembly is made up of identifiable materials that certainly don't fall into the category of OE BMW level construction.

And btw I looked, but couldn't find any info on this because every bit of information out there is focused on the hydrogen engine instead of the aero.

I'm not seeing anything in that photo that implies that the airfoils adjust as anything more than fixed position. However, Andrew Brilliant runs an underbody wing in lieu of a traditional diffuser.
I do wonder if there is a benefit to a "wing" underneath the car, as opposed to the more traditional diffuser, especially on cars that don't have a perfectly flat bottom to feed the wing. I know mounting a wing under the *** of my car would in my case be an easier install than a more traditional diffuser, and the increased ground clearance would be a welcome addition...

As an addition to the rearward part of a diffuser which is creating nice laminar, smooth flow to the airfoil, I like it. I like it less as an independent element just hanging out under the bumper. An airfoil relies on airspeed. Turbulent air is slow.
