Metro-
I have seen the videos, if that is the teal '93. It seems as if my lowered suspension and/or air dam help the car quite a bit. You can see that the tufts on my door are pretty stable. I don't know what the speed difference was, though.
Hopefully I'll be able to get more accurate data in the future
arcosine- That's pretty cool. Is there a thread here about it? Remember, though, that I don't have a VX. It's got a 1.6L non-VTEC!
FC- Well, either way, the wiper is off now. One nut is soaking in PB Blaster so I can get the motor out. Unfortunately it's not a lot of weight savings since its housing is necessary for shutting the hatch. VX's came without rear wipers, so I figure it'll be fine. I am trying to work on a permanent kammback which would, as you say, keep a lot of spray off of the window.
Been researching faired bicycles lately... someone stop me from building a recumbent HPV...
