: 06 V6 with 22's Alignment Questions

I'm looking at getting an alignment on my 06 v6 STS with 22x9 front and 22x10 rear wheels. I'm getting a slight vibration at high speeds (usually around 60mph but clears up at 70mph) as well as inner tire wear front and back. These tires aren't cheap and I can't rotate them because of the staggered fitment. I was told by an alignment shop that the shimmy at high speeds would be the tires need balanced and that there isn't a whole lot of adjustment for the camber/caster, but I'm also worried about the tire wear from camber. Has anybody had these issues and if so what did you do to cure them? I found these camber bolts online from Moog and wondered if this would cure the problem.

Check your air shocks and see if there leaking. That caused my inner tire wear on my 22s. And vibration like what you described sounds like the tires need a slight balancing. Give it a try won't hurt.

Make sure the shop balancing your tires is using a Hunter Road-force Balancer. They're the best!

Camber bolts might get you an extra 5k from the tires.

What you need is adjustable control arms. Not sure if Stern makes any specific to the STS, but you can always get a set custom built.

I guess 5k is better than nothing, custom built control arms makes me wanna sell the 22's and get 20's. I would think that would help. How would I know if the shocks are leaking or if I even have air shocks?

You can look at the shocks and if they have an bladder you have air shocks. Or you can look in the spare your cover and check the codes. I have fe3 I dont know the other suspension codes that are air ride. But I knew mine were leaking a dau it had rained and I could air the air seeping out and blowing bubbles. Plus the rear was a bit low and the compressor came on frequently.

Not air shocks really, just a bladder for load leveling, the shock has no air in it...

FE3 is the spring stiffness

My F55 MRC suspension has the same bladder system for load leveling purposes.

There are two STS leveling systems and some models may not have it at all (as I recall from member posts.) There is a thread dealing with the topic in depth. D3 used to market different kits for each application and even those kits put 'correct' alignment out of reach.

As I recall, lowering more than D3's kits without massive work caused serious handling & wear issues. I would never sacrifice my handling but it's your car, enjoy!
