Is the "sport" suspension (or club sport) a true "M" suspension?

[cmoore]

I see description after description indicating exactly what is different between the sport and the active or base suspension is. Here is my question; Is the "sport version" a true "M" level of suspension consistent with the e36 M3 or is it actually just a "S" version, improved over the base, but more consistent with how the e30 had 325i and 325is where the "s" indicated a sportier suspension, but not something anywhere near a true "M".
or in other words, side by side, does a club sport (with the similar M aerodynamics) handle equal to a e36 true M3.
Unless i am grossly naive i assume that the (for example) e36 M3 and e36 328is have significantly different handling characteristics, despite the 328is being a "sport" package. (although i don't know if bmw nomenclature is always consistent from the earliest of models)

Sorry for the verbose question, but i am considering picking up an e21, e30 or 318ti and want to have all the available info.
