j/k on the "nasty" thing ... I can guess how you know ... In all seriousness, though, the one downside to the steel is a tendency to vibration at high speed - ask me how I know. They've been known to crack tailshaft housings on A4's. And we know what the aluminum ones can do on M6's.

There was a thread on this recently and you can get more opinions there ... personally, I'd say that if you're not having any problems with vibration, just leave it. I replaced mine with aluminum when I went to 3.42's because of previous experiences with the steel ones causing bad vibrations on my 3.23 A4 LT1 cars.

Well if they can affix the weights to it, without puncturing the shaft then it can be balanced. I can have my shaft balanced by the same people who originally built it (AAM), but it's next to impossible to balance a rusted shaft because if you have to add weights, you can blow holes in it, making the shaft worthless.
