What are the best wheel stud conversion kit

[Megabass]

I bought MRG titanium but feel I should find a quality steel option. I'm not pumped that they recommended changing the studs every 3/30,000. They don't seem capable of handling track days either which is concerning for any hard driving in my opinion.

All recommendations or leads to research would be appreciated.

I recommend MSI studs, used in many types of motorsport applications, including nascar, IMSA, and global mx5 cup.

These were about the best of what I have found. Some cases where they rust. I'd assume I need 70.5mm since I don't run spacers.

Titanium studs belong nowhere near a track. See here: https://f80.bimmerpost.com/forums/sh...53&postcount=3

Any recommendations? I don't track, just hard weekend driving in the mountains.

Also I talked to MRG about this and they say this car had spacers and way to heavy of wheels/tire combo. Still should be able to hold up to the rigors though. It's a scary thought for sure and why I'm perusing answers and solutions.

Thanks for the input

You sell them can you send me a link? I was looking at MSI I can't find anything else.

Sure, PM sent.

After owning the F8X for almost 5 years and having multiple sets of wheels inside the garage that I swap out by myself often, it begs the question - what are the benefits of having a stud kit? I don't get it.. the car has a hub lip that the wheel can rest on before you throw the first bolt in. It's really not much different to me. It does look nice though, I admit. But when we know things like how titanium isn't fit for studs due to metal softness, and having to locktite and what not to ensure they dont back out really begs the question why?

I can only think of track use with spacers and not wanting to deal with two different length of bolts when swapping wheels at track. Other than that.. can't think of any

I appreciate the view and it's mostly looks and to not risk damaging expensive wheels with knuckle tire guys. It's safer to set a wheel on studs vs a hub. I think we can agree on that. I also agree, titanium is dope looking but not practical or safe. Not to mention $$$$$

I run these, no issues

Safer in what way? Both would require the user to hold the wheel onto the hub lip prior to throwing a bolt / nut. If the wheel drops off the hub lip and your studs hold onto the wheel, the studs could / would scratch the wheel slightly in the holes. Ask me how I know....

And another reason I don't understand throwing studs on as replacements are the requirement of adding locktite (some studs such as MRG require it) - extra steps taken to ensure your safety on the road, vs cosmetic safety of the wheel.

I guess I don't see the pros over the cons. With that said my recommendation for studs are MSI or Motorsports hardware. Both are used in motorsports often.

I can’t tell from the one pic but it looks the threads may be rolled, not machined. Machined threads have a sharp thread root which can lead to a crack (high stress concentration) and then eventually failure. Most Ti studs use machined threads. If these threads are rolled then they’re definitely more durable and less likely to fail.

I'm pretty sure they're machined not rolled.

[Megabass]

I'll find out for sure if they're rolled or machined. I know the future classic set is rolled.

Heard of the catch phrase? "When in doubt, throw it out." It's painfully obvious that it bothers you, because it's made of titanium. Return it.

[Megabass]

The MRG are rolled threads. I'm gonna install them, I feel confident they'll be safe. Especially after talking with a few people that have been running them for years. Sounds like issues come from improper torquing of the studs or lugs.

They do corrode as with any steel studs, so antiseize is needed for the lugs threads if you live in the snowbelt and above. All steel studs will eventually corrode, I don't care what coating they put on them. You're supposed to replace them every other year or so.

On the flip side, no race teams we work with use Ti studs. I'll leave it there.
