It would seem that your roof extension would make your car less bluff (if that is a proper term). I read through your build thread today, nice work. Oh, and my wife likes your yard I take it you are thinking about a belly pan this year as well? Our cars are actually quite similar in configuration and profile. mine is taller, wider and heavier though, and uses twice as much fuel. I have the same spare tire issue as you do if I do a rear pan. If you beat me to it I'll be looking to see what you did. It's quite impressive that you got a 10% improvement in FE even though your Cd numbers didn't change that much. This is off topic, but I still find it very cool that I can sit here and chat with someone half way around the world.
