okay i know that the IRS comes with 5 deg camber
but for some reason both of my rear suspension is at the same level from the ground and one has more camber than the other. i think it's the rubber bushings that's gone but could there be another problem? also the wheel seems to stick out further on the side that has more camber.

check your bushes, inner washers and also the placemnet of the trailing arms on the spring plates.

They do bend though so don't discount it

i think it's the bushes but when i had a look it looks like the whole trailing arm is bent or not sitting in properly when jacked up cos the camber can be noticed even when i jacked the car up and the arm all the way down
