E85 suspension differences

I have an E85 and I'm getting ready to refresh the suspension. What I don't know is there any difference between the E85 roadster with the M sport suspension and the regular E85 roadster.

Shorter/stiffer springs, bigger bars etc

Apart from the mentioned above:
Shocks also have different partnumbers.
If there is a real difference in damping characteristics, I don't know.

What do you plan on refreshing ?

I have st xta coil over, new fca, stiffer fcab from the fly (check for sale section), bimmerworld adjustable end links, my sway bar is all rusted, going to sand it, clean it and spray, powerflex front sway bushing.

Still in process of installing, so I have everything apart. Also sand off rust in the sub frame and do a little touch up rust removal.
