Very little information available between the two but I think the Z3M struts are slightly shorter which might be fine because I plan on running lowering springs. Turns out the Z3M are slightly less expensive but cost doesn’t matter I just want to get the right set up. |
From what I understand the there is no difference. Especially if you are going with lowering springs anyways, might as well get a set of used e36 m3 struts, which should be easy to find, buy a set of Koni Yellow single adjustable inserts, bring it a to a place to do it for you and you will be set with whatever lowering or stock springs you use.
Only thing I am not sure of is the e30 m3 lower control arm (LCA), if it is similar spec to the regular e30 LCAs - except being aluminum - you might want to run the offset LCAs to get a bit more caster, which will also be closer to the M stock suspension geometry.
