I'm not an aeronautical engineer, but I was hoping to hear from some. (Thanks, TRK!) My purpose with this thread was to generate some discussion, share what I've done, and see what others are doing. Although I keep insurance, tags, and state inspection on my 986, it's not exactly a street car. It's built to compete in SCCA F Prepared and PCA Improved autocross classes. Winning and losing often comes down to hundredths of a second, so I'm game to try things out to see what works. In a way, it's my hobbyist racer test lab, so if someone can make suggestions, improvements, or point out fatal flaws, I want to know about it.

By the way, I have moved the center radiator out towards the front of the car, and I added ducting to channel air through it and upwards. I don't have data on the aero, but when the car gets moving, the temps drop fast. On hots days at autocross, that's important.
