Betasniper: Thank you for the photoshoppin of the car. Can you elaborate on the "Looks like you could comfortably go out to 15% template without restricting any rear visibility if you make a kamm/roof spoiler. " I'm still a little too new for some of the technical jargon. Are those bottom numbers percentages? Is that what you are referring to?

I saw that thread you linked, good info. and something I have always wondered about bely pans and heat.

arcosine: I read your build thread a few times before signing up here so I think I am pretty familiar with your setup. I wish you used the car more though so that we could see the benefits of each individual piece of the puzzle. So you are getting 50mpg with your front bumper mod, front and rear skirts and full belly pan? Am I missing anything else? I can't remember what year the MP2 trans came out of but it was a later model, either way, Mp2 still beats MP3, and lucky for me the OBD1 cars are able to keep cruise with the swap. What is the function of the diode? Fool the map and make the car run more rich? I am thinking about a Kamm back but am unsure how to mount everything due to the wrap around glass... I don't think suction cups will last very long... any thoughts on mounting it.

Back to my original post, the link below is the one I referenced about the dead air flow study. I guess its more flawed that I thought because it assumes attached air across the back window when in reality is seems to be a vortex just like at the back of car. http://ecomodder.com/forum/showthrea...udy-24010.html

Picture below is of an SL2 bumper (I don't have the fog lights though) and I need to get the front air dam assembly which I don't currently have.


And this is an SL1 bumper:



If nothing else I think I need to at least cover the "brake cooling ducts" that don't do anything on the far edges of the SL2 bumper...
