Zach,
I live an hour from A2 Wind Tunnel,,, I jusr spoke with them last week and the 2011 prices have increased a bit.
$460 per hour. I need to check a few things on my Stude and while there with all this spolier and safety discussion I was going to put my car in backwards and test to see how the rear lifts with altered style rear spoiler. I was then going to test a hinged design and flaps in the spoiler,,
However after talking with them, the time involved to take the car out, re set it backwards and make the tests would cost another $2,000 that I don't have.
So I understand your budget concerns.
Good luck.
Charles
