Does anyone know if non-M rear sway will fit the 1M?

I've got a 135i that had M-sport suspension but now I've converted to full front and rear 1M suspension (actual stock 1m shocks and springs), M3 sway bars front and rear, LSD, subframe, etc. I can tell you that you do not want to go to 135 spec. It's just too soft with excessive understeer. For street driving it's actually quite nice but a little bouncy. Also, the suspension bits were tuned with rock-hard run flat tires in mind.
My 1M spec 135 is fantastic!!
Sounds like the classic "grass is always greener" case but the 1M is still considered one of the best things to come out of Munich in a very long time.
