Stock lock nut failure

And that was just at 135 ft-lbs... will never try that again.

They should be covered under warranty.

Scary...and you can torque to 150 +/- 15 according to Ford. How many times have you taken the wheels on & off?

I realize you weren't asking me, but I've had mine on and off quite a few times due to using snow tires in the winter. I've also had them on an off while I was doing transmission replacement. Always torqued to 150 ft-lbs.

No problems.

These wee torqued to 135 ft-lbs and failed after two wheel changes.

Torque wrench? Or did someone other before you use a n impact?

So are you switching to a better nut? Preferably non-locking? I always hated locking nuts.

I'll be researching some stock-appearing replacements, yes, but no locking nuts.

I did not think there was an option for wheel locks on the GT350, Is that a dealer accessory? Toss them and get a set of McGuards.

Factory set that came along with the car.

Yeah, I saw that coming when I got my car and skipped using those, ordered some splined Gorilla locks. Solid as a rock.

Yup. I've had mine on and off at least half a dozen times up front. 9 30 minutes track sessions and retorqued them between sessions. They're also black which I like the look of.

I had to look up the factory ones to figure out what you were posting LOL. Yeah I would be very gentle with them. No bouncing on the torque wrench and make sure the Key is always tight and flush to the nut. Other option is to torque the 4 to spec and run these at a lower torque but that may introduce rotor issues.

Gorilla "The System" lug nuts... the best - and all of them are locks.
