Drivetrain kicks when I shift

I have a 2001 e46 330i with 125 thousand miles. When I shift gears, the back end of the car thumps. It's definitely not the transmission. I can control how hard the car kicks by how quickly I engage the clutch. Its far more noticeable in the lower gears then it is in 4th and 5th. What bushings should I be inspecting?

I'd say it's most likely the rear differential bushing. When it goes bad, the diff can move upwards and bump in to the rear floor, causing that clunking sound.

I just bought a car and I kinda think I hear the same noise... its not horrible bad sounding and when I control the clutch good its less noticeable.. My 323ci has 128k on it, is this something that goes bad commonly, and is it hard to fix?
