Has anyone here had rear subframe issues?

Been reading the M3 forum and there have been many discussions of cracked rear subframes lately. That kinda scares me a little especially since I have aftermarket suspensions on my car.

Just wondering how strong the Z4's/Z4M's subframes are. Has anyone had issues with them or know someone from other Z4 forums that have had issues with the rear subframes?
 
early e46's... they fixed them for ones built after 2002 and since our z4's started to build in 2002, i don't think we have that problem... and they had M52 engines(323/328's)

The subframe problems seem to have affected E46 M3's of all ages, and not just the early 323's/328's.
