Interesting. Since the arm is split, the bushing would bind and try to compress the arm, twisting it and further binding. I gave up on the E46 (using a press kit). At the end of the day, though, the inner bushing material is fairly thin, so deflection shouldn't be so bad. My vote is for lower outer ball joint (upper is already ball joint) and E46 M3 RTABs with limiters to keep the arm from flopping around.
