Wheel Studs - Loose?

At the track last week. My son is driving the car. We both hear a slight clicking sound when turning right. We are just starting a new lap and I'm uncomfortable with the sound. Pull back into the paddock and 2 front wheel studs are gone. Half of the wheel studs on the car are loose.

The wheel studs were put in by the prior owner and this is my second summer with the car. I wasn't familiar with these being a maintenance item. On My Corvettes and Camaros, the wheel studs where pressed in and had no way to back out. I had just torqued on a set of rims to start the day and didn't notice any issues.

My questions:
Is this a common issue that red locktite can fix (good to 500 dregrees)?
Should I put a bead on the back of the hub to permanently affix the stud without warping the hub?

I did a search with no results.

You will die, eventually.

@Lotusxs - See the thread Wheel Stud Upgrades for a discussion that might have some info related to your problem.

Glen, that was an educational hour of reading. Thank you for referencing.

My takeaways are to use red locktite on my replacement BOE ARP studs and check them every couple of track days. My guess is that welding the back of the studs to the hub is a bad idea as nobody else is doing this.

Red loctite is suffcient. If you weld the studs they will not be removable. I've not
heard of anyone welding studs onto an Elige upright.
I use black BMW wheel bolts. I used studs for a while but prefer bolts.

Removing a stud with red Loctite often produces a sound like a .22 pistol. They are really solid. The PO probably just screwed 'em in and leaned on 'em.

A moron tech, ashamedly at a Lotus dealer, once put the wheels back on with an air gun or a gorilla or something. I was breaking the breaker bars (yes two) tying to get the wheels off. Three of the studs came out with a bang.

Had the dealer not been an hour away there would have been quite an ugly scene. What an idiot. Had no business working on a bicycle much less a Lotus.

Anyone can make something complicated. It takes genius to make it simple. Einstein.

I use the BOE studs with red Loctite, if anything the Loctite can be a pain as the studs can be difficult to remove ... you have to take care not to round out the head with the Allen Key
Still always good to know they are in place.
I also regularly check at the track [old habit] and replace every other season. More that they get worn from wheels on-off all the time.
Note also that BOE recommends 10ft/il torque .. so its not a lot of force required.
