Greg,

I fooled around w/ an airdam on my old AW11 MR2. Didn't have any fancy data aquisition, but did find that I lost almost 2 seconds on the long course at Watkins Glen. I didn't play around w/ multiple configurations, but couldn't really see how any design was going to get back those 2 seconds and then gain me time.
Bill,

Not to mention that if you start monkeying about with the airflow under an AW11 (at least in IT-legal configurations), you will start having issues with engine bay temps. (Which will lead to clutch hydraulic vapor-lock, etc.)
