Underneath my 2001 330Ci are two, what I suspect are, anti body flex bars or beams. They run from the jacking area on each side to the toward the rear of the vehicle in a V shape, bolted to the vehicle at both ends. What are these called, so I can look up the part and see if I can replace one? Thanx.
Casually, those might commonly referred to as 'swaybars', or perhaps somewhat more accurately, 'anti-sway bars'. BMW apparently refers to them as stabilizers - See the realoem links - multiple pictures may or may not mean there were different ones on different models.

I don't think he's talking about sway bars, sounds like it's some kind of brace for the body can you get a picture of what you're referring to?
I wonder if he's talking about B/C? Realoem is showing a pic, but doesn't identify what that is.. hmmm... probably extra unibody support for the convertible... http://www.realoem.com/bmw/showparts.do?model=BS53&mospid=47707&btnr=31_0865&hg=31&fg=80
What's a 330Ci in 2001 if not a convertible? Realoem shows a parts group for sliding roof/folding top.. if it quacks like a duck and tastes like a duck... http://www.realoem.com/bmw/partgrp.do?model=BS53&mospid=47707&hg=54&fg=10
If wikipedia is correct, looks like it could be either... Nope, not too confusing, not too confusing at all... I guess it's still better than the mumble-mouthed mess of nomenclatures we're stuck with today; confusing perhaps, but at least more concise. http://en.wikipedia.org/wiki/BMW_3_Series_(E46)#.22Ci.22
