Dropped the subframe today. I decided last week to stay with the non-m subframe as the trailing arm mounts on a slightly different angle, it would be ok as in putting ball joints into there but just doesn't sit right with my OCD ( can be seen in the photo below ). As such I order some hardrace toe arms instead of using the M3 ones. Next step is to install the aluminum subframe bushing which should turn up tomorrow, replace the diff bushings, install hardrace toes arms with eccentric lockout, replace the trailing rubber bushings with ball joints and install the m3 spring arms ready for m3 shocks. Should make for the perfect rear end, fully ball joints and solid subframe bushings.
