wagon Kammback?
 

I have a wagon as seen below

I am thinking about a few ideas to clean up the air as it leaves the back of the car.

or
2. a partial boat tail.

personally I like the idea of a wing that directs the flow in a more beneficial direction.

The roof rack has to stay since the air bags are mounted directly below it and I'm a chicken.

I've been wanting to do something for over a year. Here is a mock-up of what I am thinking of doing :

But, I have another test in progress right now, so I think it is a month away.

philip 1,
When (if) you get a scangauge or other onboard mpg readout, leave it off while running the Autocross course. It depressed me to see that my runs (HS) consumes fuel at about three times the rate of typical daily driving.
What have you done to go into the STS class?

I've actually retired the wagon from racing it's now just a driver. a scangauge is on my wants list.

I find it hard to believe the roof racks are integral to any airbag system.
I can only assume you are talking about airbags mounted at the roof/headliner? Maybe they share a bolt with the external racks...but as long as you maintain a solid mount of the airbag...lose the racks;)

the bolts for the rack are above the airbags and I'm scared to mess with them because of that.

I understand your trepidation, but I am also curious. Maybe this is a question for www.saturnfans.com. I am sure that one of the online Saturn repair techs could give you a professional answer on this. I am thinking there must be a set of steps where you disconnect the battery, remove the racks in step a, b, c, d, and reconnect the battery. If you are not a member, I can ask the question for you.

Can an airbag deploy without being connected to the battery? The manuals always say that you should disconnect the battery to prevent the airbag from being deployed.

I'm on saturnfans.com same name and everything. I have mentioned this there. So far no one has said go for it.

Ok, I was being lazy and didn't search saturnfans. If they didn't give you the go, then I wouldn't do it either.

after pondering this for a few days I have decided to try on my next 2 month cycle some delta VG's just ahead of the hatch gap and we will see if they make a difference.
