For whatever reason, due to either worn trailing arm bushings on one side, a bent subframe or otherwise worn suspension components, I have uneven camber when lowered the same amount on both sides. LR is -5 degrees and RR is -4.2 degrees with no adjustability, and there is a visible difference when viewing the car from the rear which is driving me nuts
$85 CAD later, problem solved

arriving on the 24th, installing on the 25th. Looking to get the RR to match the LR's -5 degrees of camber.
