all OEM non-M3 suspensions the same?

UpOn3 · 12-11-2010, 12:32 AM

Are all E46 suspensions of the same geometry? With the exception of the springs/shocks/sways/brake diameter, do they all have the same suspension parts (same part number?) ?

Perfect offset appears to be 47 based on most of the stock wheels, but why do the 330 Sport wheels (Style 68 fronts), have a lower offset of 41? and why didn't they just go with 8" wide wheels like for the 325 Sport (instead of 7.5")?

Are you for real?

yes, all non m3 suspensions have the same geometry. In fact the only difference in the M3 is the front control arm is longer, the rear is the same as all non m3s. Well, actually there is a difference in the upper front strut mount too, but that is because of the longer lower control arm.
