I had no idea this thread was Wiki'ed
Cal98Civic, I've been following your work in the "Bonneville Spoiler" thread. Thanks for your work there!
I laid off of the aero work because I realized that there is more happening at the back of the car than I am able to understand. I have been able to achieve my goals by other means, so rear spoilers and decklid extentions became a non issue.
If you've read my thread here, you'll see that I saw a negative result with my spoiler. My best guess is the air wraping around the the very rounded rear pillars interaction with the spoiler cause this negative result. My belief is some tuft testing of this area might help me design a spoiler that would be more effective.
Everytime I start to read about this stuff I just want to get carboard and tape and go at it
Just no time for this lately...
