Hi all, I'm in the midst of upgrading my shocks; which requires taking the shocks in and out to test fitment. I have a little lull while I wait for the final shocks, so I want to put the factory shocks back in so I can move the car if I need to. In the 365/512 workshop manual; it says "Torque specifications in kg." – so I am guessing it's kgf•m? If I am reading the below correctly, that's 5.6 kgf•m for the M12x1.25 nylon lock nut (40.5 ft/lbs) that connects the wishbone to the frame? Seems low for 10.9 M12x1.25 bolt, no? Thanks in advance.

If tightened to a higher torque it wants to twist the fork, binding the arm and possibly damaging the bushing. It is always good to check in multiple sources because Ferrari has so many errors in the torque specifications. I would but have none of my books at my disposal right now. Also many do use a higher torque on those but some means of counter holding the fork to prevent twisting is required. I would also suggest applying some anti seize where the stud goes through the frame to prevent rust from developing and seizing the fork to the frame. Also just for the sake of being able to roll the car around absent the shocks I often just use a piece of heavy gauge flat iron stock or square stock with holes drilled at the approximate length of the loaded shock and install those. Not for driving, just for rolling it around the shop.
Thanks Brian, that's very helpful. Appreciate the context as well. So does 50 ft.lbs. seem reasonable? A little more than the workshop manual is calling for, but less than your "typical" torque for a high-strength M12 bolt?
I have never seen a torque wrench used. On many services including the very first service nut and bolting the suspension parts was required (they do come loose) and in 40+ years including being in the dealer who sold the most BBs world wide never saw a torque wrench come out for the suspension.
