In this thread it says 80 lbs for the front ones and 40 ft lbs for the rear. Im very confused why they would be different. Also the initial post says "Front 6 and rear 2"... there are 7 bolts, not 8. This pan on the E46 uses stretch bolts and it is critical to replace them and properly torque then as it ties the front suspension together. I am not sure if this is the same with the E9X.
Weird, looked at the diagram and I can see what you're saying about the published torque specs. Weirder thing is on my car all the belly pan bolts are 16mm and I probably give them 40lbsish.. my cars an '08 build. Maybe they were replaced before so maybe they do strip easy.
