As far as I know... nobody really makes body kit for the 9000. If you dont already have an aero, you might be able to sniff out one from a dealership/junkyard etc. (the aero had a special, better body kit on it). you could always get one custom made... but that would cost $$$
i'm currently working on making a front lip/spoiler for mine. I stole the concept from and 80's M3. I let you know how it comes out, and should aways be able to make more as i am making a fiberglass mold.
Just FYI, Aero side skirts will fit on the early body style. I think if you then painted the lower front airdam and the lower portion of the rear bumper, it would look pretty darned good. Naturally, it wouldn't be as nice as an Erebuni or Airflow/Carlsson front and rear bumper. But, Aero side skirts for sale seem pretty easy to come by. If they happen to be in the color you need, so much the better.
I just called Erebuni today and got a bit of information. At this time, all they have for the 9000 are the front and rear bumpers. The price I think is quite good, at $359 for both, though shipping is $160 within the 48 states. The description they have on the web site is not quite accurate. Their parts for the 9000 completely replace the front and rear bumpers - or at the very least, the bumper covers. They do not supply any hardware, but say it will mount with either the stock hardware, or whatever your installation shop can make work. Also, since they are fiberglass, they say the pieces should only be painted after being mounted to the car.
So although it's only $520 for front and rear bumpers, you still have installation costs, then painting costs, neither of which seem inexpensive for quality work. I am also leary of fiberlass parts, though perhaps irrationally so. I think I'll just have my stock front airdam painted, and keep my eyes out for Saab airflow front and rear bumpers.
