I got the X5 springs yesterday and installed them last night. The car is still on jack stands for brake job and exhaust repair. I'll see if the stance is different (I forgot to mesure height before and after. damn!). Here is a pic of the X3 and X5 springs side by side. Quite similar, maybe 1/2 inch lower...

Alignment Settings

A new owner of a 9-3 Aero V6 xwd (Canada) which I believe has the Turbo X suspension. Shocks are B8 Bilsteins with matching springs of un-known make. I just bought BFG Comp 2 all-season tires on 17" five spokes second hand and wanted to get the car aligned. I gave the specs for the Turbo X to the shop. Everything went well except the rear camber adjustment. Stock is -1.0 and we ended up with -1.8 and -2.5 (L/R) with toe aligned to spec (0.10). Camber could have been adjusted with the lower control arm bolts, but it would have thrown off the toe. We decided to set the toe and live with the camber.

The xwd system does not appear to use the same alignment shims as the front wheel drive cars, so there is not an independent camber alignment mechanism for the rear. The Tech suggested the problem may be upper control arms that have be bent resulting in them being shorter, hence increasing the camber. The bushings appear to be tight.

One suggestion was to buy new upper control arms and check the length against the existing ones. Another option would be to slot the upper arm bolt hole (towards the outside) and reinforce the opening by welding washers each side. We are not sure whether this can safely correct the alignment and is a semi-permanent modification that should not be necessary. A third option would be to install some type of eccentric bushing to increase the effective arm length. The last option is to design and fabricate some form of adjustable upper control arm that would allow adjustment of the arm length. This would allow camber adjustment without changing the toe. I have seen similar systems for other cars, but not the 9-3. Any one have some rear control arms they want to donate to the cause. Any suspension experts out there who can comment?

B8 + matched springs automatically makes it a non-Turbo X suspension.

Turbo X rear suspension uses much softer springs, paired with self-leveling Nivomat shocks which compensate for lower spring rates and any additional load. All other rear suspension components like links and control arms are the same on every XWD 9-3.

You can start with checking your ride height at rear, by measuring the distance between the center of the drive shaft and the top edge of the wing. It should be 374mm for Aero specs, and 364mm for Turbo X specs.

Rear Alignement

When you say "center of drive shaft to top edge of wing", is this the same as the centre of the wheel to the underside of the rear wheel opening? This would be much easier to measure accurately. I will measure the distance to establish ride height as compared to the Turbo X, but regardless, I believe I still have too much negative camber and will be looking for a solution to correct it.

2010 2.0T XWD Sedan, Changing Diff Need Control Module

Good evening. My Tech Diagnosed the Control Module on my non ELSD rear diff as having no communication with the Bus. I'll need the Module when I put the new diff in as a diff with the correct Module is no longer available. The part numbers associated with it are 12811305 and 12845059. I've sent the Module to BBA reman in hope of repair. Any insights where one might be available or other substitutes. Thanks

I have a Turbo X and find the ride too firm for our rubbish NZ roads, I want to install a standard suspension - same as the 2009 Aero XWD v6 had - looking at the EPC is like greek there are so many combinations of shock and spring to choose from! Is there an aftermarket kit that's not 'sport' or 'firm' ? (wow - I sound like an old man....)
