I don't think you'll find that the 9000 has the range of adjustments that are availible on such machinery as the Elise. If it is possible then I think that it would be a case of placing shims in the appropriate places as there is nothing other than straightforward tracking toe in/out AFAIK.
I replied to this before but my post seems to have dissapeared
Anyway Nick is correct unfortunately the 9000 is not adjustable only toe is.
Unless you feel you have a problem with your car a computerised 4-wheel alignment would be a waste of money The cost of a alignment check varies between £40-£140 depending on machine/garage used but in the main £80-£100.
I am having big probs with my 9-5 at the moment and I'm on my 5th alignment and have around 6 hours labour involved just to get the rear camber and toe right after lowering my car and fitting 17" alloys so just imagine if I had to pay for all this
I'm sure I've got it right now and will give it the sixth alignment some time this week (hopefully)
Edit: all the probs are because the Modern Saabs are non-adjustable The rear toe on the 9-5 is but not enough was available for my set up.
My 9000 had heaps of +ve camber on the left rear wheel (must have had a clout at some stage in it's earlier life). Would be nice to be able to get a bit more -ve on the front of the 9-5 to keep the outside edges of the front (esp. left) tyres from wearing away long before the rest of the tyre.
