Good stuff. I like the idea of using the starter hole as an exhaust outlet to blow the diffuser, and wonder if the proposed upper outlet might be used to drive a venturi section incorporating the beam wing. Also, holy shit front wings are crazy. Crazy awesome.
(Related programming note: the 2011 24 Hours of Daytona starts Saturday at 12:30 PST. It ought to be pretty damn amazing — note that Flying Lizard is running a Daytona Prototype this year, and snagged pole in the Porsche/Riley that David Donohue used to win in 2009.)
