Fresh Bolts Needed for Rear Subframe Vincebar Job

[BMWahba]

Hey everyone,

Does anyone have a semi-complete list of bolts that should be replaced when having the entire rear end out of the car for a subframe job?

Besides the front diff bolt and 2x rear diff bolts, what else is a good idea to replace while in there? I'm sure this was on old m3forum but can't find any more archives
The rest of the hardware I plan on zinc plating, but want to be sure I don't reuse something I shouldn't be, so in which case the purpose of this thread is to advise on which bolts should be refreshed with new hardware.

Thanks all!

If you will be extending the mounting bolts into trunk and back seat area with a reinforcing bracket, you will need 12mm x 1.5? threaded rod longer than the stock bolts. I know I had a heck of a time getting the fine pitch 12mm.
I don't remember how long they need to be either but if you are buying threaded rod 3ft long you should have enough.
