rear suspension damage
i just replaced my antiroll bars. the metal supports for the bar in the rear were almost broken off!!
just as the subframe failures, this seems to be a very weak point of the e46. i did purchase weld-in metal ends from turner motorsports, and had them installed, which (tms says) solves the problem for ever.
it seems that the rear suspension cannot take u.s. style potholes: i am wondering if anyone has seen this failure as well.
