No worries D!

Personally, I like race cars, where wings, spoilers, and body shapes have meaning and purpose. If, in the process of optimizing their performance, you can also make the vehicle attractive...well then you get to satisfy your particular aesthetic sensibilities, but little else. The XF is a beauty...you haven't detracted from that at all. And please don't worry about it either. GO FAST! Allez Derek...your doing great!

Woody, one thing you've mentioned above (and previously I think) regarding airflow in the underbody. Specifically that it was given serious consideration. In addition to that, would it not also be worth considering the movement of air around the front end and along the sides as well. Looking at DTM/BTCC cars, another thing worth considering...since we're spending Dereks budget, is some fairings around the wheel wheels to push air from building up in wells? The front end slides straight back on the standard XF...would it not help to push some air away from the wells?

Also: note the venting for the wells here:

Probably too much to consider for this year in the end...just thinkin out loud.

Just to show the beauty and beast relationship...2006 Renault f1 from the rear...
