Rear diff
mounts - clean up/paint
diff - check backlash
rear subframe mounts
rear arb - uprate to whiteline
rear tie rods
rear wishbones - seam weld clean up etc
drop links
coilovers/shocks/springs
rear bearings
rear abs sensors
stud conversion if your that way inclined
uprate the rear discs/callipers
rear braided brake lines
rear diff mount (big one)
side diff mounts
new nuts/bolts
new prop bush whilst your there
rear exhaust hangers
handbrake cable

can you guess what i've been doing today
can add more to the list if you want

I did every bush, every oil seal, new cv joints, new bearings, new brake pipes, new mountings etc etc. oh and got everything powder coated. I suggest that basically you do anything thats going to rot/wear or leak!

been messing with the rear end of a car today so its fresh in my mind.

pretty much acidburn said, through I went with a 22mm arb from front a coupe and solid subframe bushes along poly or nylon every where else
also worth thinking about is a V8 torsen, thinking might try getting one in america when there unless one come up cheap here

[Acidburn]

whilst the cars up in the air its worthwhile checking what the underside is like, if possible sourcing good heatshields etc.

Every nut/bolt for the underside cost me £110 first time round and remember some of them are no longer available now.

Uprated bushes are a good idea, por15 is your friend as well, basically just look at every component and think, how long did audi manage to keep it in one piece and does anyone do a better upgraded version i.e. bambridge.

Yup the nuts and bolts add up pretty quick, much nicer (and safer) having new ones to re assemble with though.

I think acidburns list is fairly comprehensive

I'm not going into engine/clutch/box issues unless people want me to lol.

It all quickly adds up as i'm finding out.

Just do everything

Biggest thing I can recommend as I have BTDT is check for rust - anywhere you see a bit in the underseal i can almost guarantee theres 10x as much underneath it nearby as it spreads out unnoticed...
