Does anyone know what is the torque value for 991.1 lugs tightening?

 

118 ft-lb or 160 Nm

 

118 is correct and if you have wheel locks it’s less so be careful you don’t strip your wheel bolts.

 

991.1's come with the factory locks that match other bolts besides the pattern. This is the first I've heard it would be any different and been torquing to 118-120 all along (?)

 

It’s 118 including the lock lug
the older 911s are 95 or so But use anti seize lube on the threads and seat

 

Yes I searched and noticed 95 for older 911s but didn’t find 991 anywhere. I’ve got locks too. So looks like it’s 118 lb-ft!!

 

There’s information out there that recommends not using any type of lubricant on lug nuts or bolts.

Adding lubricant affects the torque force and may actually damage the fasteners over time.

 

NEVER use any thing on the threads! It’ll give u incorrect torque values. Anti seize on the contact points on the rear of the wheel ONLY.

 

you guys missed my comment. OLDER 911s
older 911s have aluminum lugs
it is 100% factory process to use anti seize on the lugs and the seat

ask the old timers how many busted lugs they have seen due to the lug seizing

this is not a problem with steel lug bolts or the design used on the newer cars.

fwiw, the factory spec on my 997rs is 95 (in the manual) but i believe Porsche superseded that to 118

 

What do I know, I stripped one of my lock bolts by trying to torque to 118 ft/lbs. I exchanged all my lock bolts to regular wheel bolts. 😐

 

I too dumped the wheel locks haven't had a wheel stolen yet...perhaps I'm living dangerously...

 

Please could you elaborate on this? I have wheel lock bolts on my ‘17 991.2, 1 per wheel. Are these bolts not able to hold up to 118 ft lbs?

 

My experience is that the key or the lock can get stripped when being tightened or removed. Frankly, the last thing I wanted after a flat tire was a missing wheel key.

 

Ahhhh...the splines. Ok, I can see that happening. Thanks! That's probably what happened, but I'm still interested in @97supratt 's experience.

 

I stripped the hub by over tightening the wheel lock. From what I remember from experience, you tighten every lug nut or bolt and the last one you tighten is the lock. The torque spec should be less due to the fact that it’s only a lock.
