Rear brake pad weird wear pattern

[ghostuss]

Yea today I took my rear brake pads off due to the noise from pad wear warning and found weird wear pattern. Both inside pads of my rear pads had this huge uneven wear. Like on either one of them has this tilted wear angle, where one side of the pad is still fat and the other is almost gone. The outside 2 brake pads are still good, kinda tilted on wear but still got a lot meat left, but the inside 2 pads is all worn down to sensor. HMMmmm.. anyone got any idea what might cause this? I am thinking bad camber? Bad rotor placement? I did have new coilovers put in like a few weeks before I heard the pad wear warning noise. ppl help plz, I don't want to put in new rear brake pads every other month.
