Thanks guys....just an update...I was back in there this past week doing my LSD and M3 upper control arms.
RSFB still look like the day I put them in. I actually had to lower the rear part of the subframe to get my rear differential bushing changed and took one of the RSFBs out while I was in there to examine it...looked great.
Here's a couple pics.
