Inside Rear Tire Wear

2004 Mazda 3 with 142,000km and OEM (or OEM replacement) suspension, ie. not lowered.

My rear tires are wearing faster on the inside and I'm almost certain it's because of the camber which is around -2. I had my wheels aligned at 140,000km and everything is within spec, but apparently the aggressive camber can eat tires regardless. Rear camber isn't adjustable from the factory so I would have to get aftermarket control arms. I bought it used and I didn't get the service records so I'm not entirely sure what has been replaced or when. Rear shocks are aftermarket but I assume the rest of the suspension is original.

I would prefer to have longer tire life even if it won't handle quite as well (maybe around -1.3 as suggested by the spec sheet). Is it likely that the rear coil springs have sagged a bit and increased the negative camber, and would replacing them reduce it enough to slow down the uneven tire wear? Or should I just buy the camber arms and forget the springs? Are the springs likely to fail in the next few years anyways?

When did you replace the rear shocks? What did you replace them with? My rears were blown and it caused this, I didn't even realize they were blown because it was so gradual of a change. The bounce test didn't work because the springs are stiff.

Checking the rear shocks is extremely easy-
Put the rear of the car on jack stands, support the lower control arm with your jack and remove the shock mounting bolt. The control arm will swing down a little bit and should give you enough room to try to compress the shock to check for damping.

It could be toe and the camber both causing wear, the 3 has a pretty aggressive alignment setup that's not very friendly to tires. If you have them set it to spec they will just get it within range. You can have them zero your toe but the camber is not adjustable without installing adjustable upper control arms. Go get a free alignment check if you can find a shop nearby that does it and compare against your alignment from 4 months back.
