My 2008 Mazda 5 is eating through the inner side of the front tires, so what would be the right way to go about solving this problem?

From what I have read, the 5 doesn't have a front or rear camber adjustment, so it seems like this would require an upgraded linkage.

If the correct solution is upgrading the linkage to an adjustable one, what would be a good choice of parts? The autoshop suggested replacing the shocks, but that would seem to assume that the new shocks would put the suspension at exactly the right height.

In case it matters, the car has about 120,000 miles on it. It might be close to time to replace the front shocks, but I would still like to have a properly align-able front suspension. Seems crazy that Mazda didn't provide for this adjustment.

 

Would these camber adjustments plates be the right thing to get? Not sure about the company, as I have never heard of them before.
