Blunt,

ETK lists the part numbers for the E30 rear subframes;

M3= 33 31 2 225 593

325ix= 33 31 1 135 456

325i= 33 31 1 135 546 (almost all other E30 models)

My understanding is that the only difference in these subframes is the trailng arm pick up points to adjust the geometry of the trailing arm for the different factory ride heights (the M3 being the lowest).All E30's (well most for sure) use the exact same trailing arm. So geometry changes had to come from somewhere else. Yes this is fixable with adjustable camber/toe kits... on an e30.

Since I am putting this under an 02 that I plan on lowering a pretty good amount, I wanted to start off with the M3 subframe. I will also be installing a full adjustable camber/ toe kit, but I don't want to put all that time into making a subframe fit and then find out that I haven't got enough adjustment to align the rear end and have to start over.

A regular E30 subframe might work, but using the M3 will put the center point of the adjustment better situated for a lower stance providing a better range around the area that I expect to end up.

The front struts that is a whole 'nother story. I'm not 100% sure what I am going to use upfront.

I cringe everytime I pull up a part number that contains "225" in it. (M3 specific)
