Thought I would post some torque specs that I have been compiling. I am planning on installing the VFF700 ST kit either this weekend or next depending on when it arrives. Then in march over spring break I will be doing all the drivetrain mods. There are a few missing in the second table that I will try to fill tomorrow when I can get back to my Bentley manual. Some specs that I have had trouble finding were the specs for the subframe to motor mount bolts. I did list what I found on E90post, but I am not clear if that is all the bolts.
Let me know if you think I am missing anything and I will add them.
Torque Specs

Part ----------------------------------------- NM / lbft
Spec 2+ Clutch / Quafie (Diff. built by VAC) / DEFIV Lockdown Kit / DSS Axles

Also pulled these from the Bentley Manual.
