My Ride: Metallic gray '05 545i Sport Black Leather with HUD, Step, Nav, PDC, CWP, K&N Air Filter, Black RPI scoop, Black painted calipers, 35% F1 Pinnacle tint, 19" RDSport RS-2F rims with Continental ExtremeContact DWs.

A few weeks ago, I was pulling my '05 545 out of a parking space that had a curb to my passenger side. I got in, turned to the left, and blam, backed into and up a bit onto the curb. Good news, I hit it so square that I didn't even touch the lips on my RD Sport RS2 F lips.
Driving home, it pulled a bit, so I took it in and my mechanics replaced a lower control arm that was bent and got an alignment. Drives fine, but there is a vibration/clunk when I brake that started before I got the repairts done, but seems to be getting worse. It feels like something is moving back and forth a bit, and it only happens while braking, usually hard.
Anyone have any ideas? Thanks in advance.

first thing i'd check is to make sure the lug nuts are tight.
does the steering wheel shake when braking? do you feel it in the brake pedal?

did you get that wheel rebalanced to make sure it didnt get bent? even though you didnt make contact with the rim, the inner barrel of the rim could have gotten tweaked from the impact.
usually when you brake and feel vibration, its a sign of warped rotors.

Checked today. There are no vinbrations felt in the steering wheel. That being said, while the rim has a little run-out, it doesn't feel like a warped rotor. I've had warped rotors before and I know what those vibrations feel like. This feels more like a straight back and forth action. I think maybe the bushing issue may be a factor. I had the wheels off today, and everything feels really tight. Maybe a trip to the dealer is in order.

Well, took the car to the dealer. Verdict, two broken transmission mounts and one motor mount. Motor mounts covered, transmission mounts not ($817). The SA and I have no idea how they could have nroken, and he said he's never seen it before, lucky me. At least it'll be solid again after it's fixed. BTW, they have a black M5 and M6 for sale there (both $50K), awful tempting...
