removing the windscreen entirely will cut your frontal area by ~40% and have a huge impact on drag, regardless of open cockpit aerodynamics. It will also lower the center of gravity and greatly improve the performance of the rear wing.
If you were to go "all out" then the car pictured above is the way to go but then again why bother? Get a Radical and be done with it. There is improving a car's performance and then there is stupidity just for the sake of it.

I understand what you are saying but, if you went all out in search of aerodynamic efficiency, ie, asm, with a enormous budget, couldn't you just take off/cut off the current a-pillar, weld on a new a pillar with a different rake and fabricate a custom polycarbonate windshield, then use an intricate roll cage for roll safety? The S was designed as a roadster, so as a stock car, it needed that rollover strength, but when you are making a racer, you ditch the softop and add a hardtop, you add a roll cage, and you strengthen the chassis. Why couldn't you modify the chassis in this way? I'm just curious, and you have a LOT more experience than I do since your car is in the Canadian touring car championship, so I would love to hear your input. (Do you have a picture of the full chassis? I only found this: http://www.s2000.com/s2k/xbone.jpg, I can't tell about the a pillar). Also, if you can't do it that way, couldn't you just make a whole new chassis with that one change (and others as seen fit for chassis reinforcement)? I'm going to work on the UC Davis FSAE car, and they constantly are making adjustments to the chassis (and building new ones). I don't think changing the rake/a pillar would need to have new body panel attachment points. LOL, if Honda made a coupe, this would be what they'd have to consider.

Thank you!
Screw the camera technique and its +/- X% result...
This will be SOOO much easier and also more accurate--don't know why I didn't think of this (I also have the FSM).
Thanks again!
