I just installed a factory spoiler on my wife's mini. Does anyone know the torque values for the nuts? There were no directions in the box. The ones I found on the internet don't show a value. Sorry, but I am particular when it comes to things like this.

 

I may be way off here, but generally fasteners which require very little torque are not spec'd in manuals. I'd suggest a very light touch and if there are no lock washers, and you're concerned about them loosening themselves, then a drop of light grade loctite? Those studs are mounted to plastic. Too much torque will break the wing.

I'll try to post again after I finish transferring my JCW wing on in the morning.

 

I mounted our JCW wing this morning. Given that there are the 3 pin retainers and the 5 nuts, that the studs are mouted in plastic, and they're little old 10mm nuts, I took it easy on them and gave it the mild just-so tightening. Remember using the right tool helps you gauge the torque needed. For this one I used a 1/4" ratchet. Small ratchet limits your ability to over-torque it.
