prehaps, I guess an example would be helpful, I'm having a hard time visualizing. would the kammback start where the rear window meets the roof, as on a hatchback? or would it start at the back edge of the trunk

I'm not opposed to something radical like a boat tail or kammback, but I'd like to start off small. remember I only drive the car on the long trips, it's the wife's daily driver. I have to keep her somewhat happy with what's going on.

take a look at those links, good pics to illustrate what you need. if you make the tail removable then you are happy and so is the wife

My CRX boat tail was fabricated on the car and could slip on and off like a glove.It had its own lights,an electrical umbilical which plugged in like a trailer,and all I had to do was move the license plate when I used it.
There are some really nice receiver-hitches out there now.You might fabricate a short tail based on a light cargo platform which slides in the hitch only for roadtrips.

Inflatable boat tails are also an option.They're the lightest of all.A simple cardboard and tape pattern can be fashioned on the car which is used to tailor the envelope fabric.The envelope is attached to a shallow box which contains the 12-VDC fan which inflates the tail,powered by a cord leading up to the battery.It's a quick and dirty way to pick up 4-mpg with just a 'shorty.'
An alcove is tailored and sewn to allow the license plate to be displayed.

that's not so bad. unfortunately I don't have a rear receiver to attach it to, or that would be ideal. Is there particular shape I should be striving for with the boattail?

If it's as easy to remove the mirrors as you say, I might try some A-B-A coast down tests

[Weather Spotter]

Idealy you want a teardrop shape that tapers in on all sides at about 13 degrees (12-15).

The mirrors usually have a plastic cover then 3 bolts.

You can get a step bumper receiver for about $30 at walmart, bolts to your bumper. Any extension you add won't weigh enough to make a problem.

that sounds promising, I'll look into that

personally with the top as earodynamic as it is i'd focus on smoothing out the rough edges at the bottom.

my advise is full front and rear undertray, tire dams, airdam extention at the side in front the the wheels,(shield the wheels and push air around but allos air to flow undetrneath at the center ) rear wheel boattails (i just run lengthwise fins after them made from plastic L bracket so nothing fancy but it fills in the wake a little) a partial or full grillblock is also a good thing.

for the undetray i made the front in coroplast, the section under the engine in thin aluminum and tha back in coroplast with a large hole for the exhaust
