My original subframe was damaged just like e46m3tony when one of my front diff bolts snapped. So I ended up buying a brand new subframe from ECS tuning and transferring the wheel carrier, it's associated arms and the stabilizer bar over to the new subframe. I have access to a tech manual, but for those who don't here are the torque specs.

Stabilizer bar to subframe = 21 NM
Stabilizer bar to Stabilizer link = 58 NM

Trailing arm to subframe = 100 NM
Trailing arm to wheel carrier = 100 NM

Guide arm to subframe = 100 NM
Guide arm to wheel carrier = 100 NM + 90 degree turn

Upper control arm to subframe = 100 NM
Upper control arm to wheel carrier = 100 NM + 90 degree turn

Toe arm to subframe = 100 NM
Toe arm to wheel carrier = 100 NM

Camber arm to subframe = 165 NM
Camber arm to wheel carrier = 165 NM

Compression strut (or V brace as tony calls it, either way it's the 2 black support bars that connect the front of your subframe to where your x-pipe is mounted)

Compression strut to x-pipe mount = 24 NM
Compression strut to chassis (2 E torx slightly forward of front subframe mounting point) = 47 NM + 90 degree turn
Compression strut to subframe = 100 NM which is of course the same torque as the subframe, since the 2 pieces are joined together

Another side note. Tony used a lift table when removing his subframe and diff, I used my transmission jack, works just as well, just ensure the chain is snug around whatever you're raising or lowering.

Thanks to e46m3tony for starting the initial thread, and I hope this additional info helps those who need it.
Quick question:

How many bolts/screws are there on EACH v brace? I'm confused about what realoem is telling me... Let me know if my below understanding is correct:

Mounting v brace to area near x pipe bracket (item no. 05)
-2x?
-M8 or M12?
-24 NM? (seems low for a big bolt)

Mounting v brace to body (item no. 06)
-2x?
-47 NM + 90 degree
-are they of different lengths? one is 35 mm and the other 25?

TIA!
