There’s a website that shows all of the wheel stud conversions that have failed at the track. It’s best to stay with oem spec wheel bolts in my opinion.
Lug nuts and studs are both consumables. If you are taking wheels on/off a good amount, lugs and studs should be replaced on *at least* an annual basis.

Depending on my track season, I either replace my studs twice a season, or once a season.

Anyone know of replacement lug bolts with the swivel washer to protect the wheels?
These are the ones I’m using. Longer than factory length for thicker aftermarket wheels.

the only studs I would put on my car are press on, but there isn’t a conversion for the Supra yet. It’s just more riskier when stud manufacturers recommend 25ft lbs on the stud when installing it. Good for you if you like studs. I won’t put them on my car. You’re right both are consumables, but in my opinion the screw on studs are more likely to fail.

Yea, also not going to happen anytime soon. I already looked into this with Core4, the OEM hub doesn't have enough meat/clearance for this. So we would need to convert to other hubs that offer that and nothing there yet.

It’s just more riskier when stud manufacturers recommend 25ft lbs on the stud when installing it.
Not sure what you mean by this, that is just to make sure they are snug to the hub.

Why do you think studs are more likely to fail? Design wise or user use wise?

I don’t think 25 ft lbs is enough to keep them on if you are using impact tools. I used to have a set of Motorsport hardware wheel studs and they would easily back out even with loctite. I remember taking my car to a shop to get some suspension stuff installed. When I took my wheels off, the studs were loose.

I think the best screw on studs are made by bimmerworld. They have race studs that recommend 75ft lbs for installation and are engineered to ensure there is less fatigue on the weak points of the bolt. I personally would still stick with bolts, but I think these are the better engineered screw on stud.

Studs are more likely to fail because there are forces exerted on the screw in part of the stud, which causes fatigue in that area. After a while they just snap. Just take a look at these examples:

If you want to trust studs, that’s fine. I just want to inform people when I can on the risks with screw on studs. I just don’t want people’s wheels falling off at the track.
First of all, I'm not advocating for either, but I am advocating for people realizing both are consumables. I run the bimmerworld premium studs, and moving to MSI soon. I had Motorsport Hardware studs before, and they are anything but motorsport. Would get loose all the time. I snapped about four of them. They are trash. I moved on because I like my wheels staying on the car.

If people do go with wheel bolts, it’s recommended to stick with OEM type of bolts that are grade 10.9 and do not have thick painted coatings on the mating areas as that can loosen the tension on the bolt overtime. OEM or H&R are the wheel bolts I have been using.

Any reason for the switch from bimmerworld to MSI?

I have the same model wheels but in a different size, 18x10 square all around w/ 5mm spacers

I run the Motorsports Hardware kit M14x1.25 to M14x1.5 conversion w/open end monster lug nuts

How long have you been running the Monster lug nuts? I had MSH lugs that were less than a year old, never saw winter, and were too rusty for my liking already.

I ran them for almost two years until I swapped them out for a new set two weeks ago. They do rust as well, since I drive my car daily and it sees mild winters. I can show you a pic of the old lug nuts sometime this week.
