Wheel stud kit on order ... now worried about them breaking on the track?

[jareds941]

The endurance racing teams I'm close with have switched to press-in wheel studs. While certainly not failure proof, they are significantly better.

since last june, i've gone to the track 16 times and i run apex wheels/studs and had zero issues. i'm probably going to change over to the FCP set and do a full swap annually with their warranty. in 2021, i'll finally be joining in NASA time trials.

So this is what I was thinking of from Turner - MSI. Pricey, any comments on how this compares to the Motorsports Hardware? I do weigh whether it better to pay for MSI and replace every 3-4 years vs buying something cheaper and replace every 1-2 years?

The answer to your question is "How much are you tracking your car?" and "How much failure risk is acceptable?".

If someone has a well-documented performance record from MH - please post the links. (Performance record doesn't IMO = "Mine haven't failed yet" or "I pretty much only use them for street".)

Just for the record I also have Apex studs...1 year now with about 5-6 events and so far they’ve been fine with no issues. Wasn’t aware of the issues with Apex studs, nor the studs offered by FCP. I would go that route next time, probably in a year.

I had apex studs on my car for two years, 4 or 5 track events, no issues. Just switched to BW studs this year, but haven’t made it to the track yet so will see how they hold up.

After a rear stud failure at Mid-Ohio two years ago, I switched to MSI studs. I carefully torque them with a Snap-On torque wrench (calibrated every two years) and never toque them when they are hot. Even with all that, I'm still changing them every two years for peace of mind.

What brand were your original studs that had a failure? Bimmerworld?

Is that car tracked?

Only a few times years ago, haven’t had time these days so it’s been pure street duty.

Wow thanks for all the replies. Even though I’m only going to do 2-3 events a year I’m going to swap them out for piece of mind.

I haven’t heard or Motorsports Hardware - does the brand have good reputation? I know MSI is well liked on the Porsche boards and is a supplier to NASCAR, is also much more expensive. This is the way I am leaning.

My neck is worth more than saving a few dollars. As I said before - I use MSI so I don't need to think about it.

Whichever way you go, treat them right and know what shops are doing to your studs. You can always hand them a torque stick rated at 80 ft/lbs.

Somehow managed to misplace 1 lug nut from the kit, can’t find it anywhere. They want $11 for shipping for a single lug nut 😐

When you get your replacement - I recommend you white ziptie the pair. Thats how I store mine.

Unless you replace good ones with failure prone ones 😬. Since mine have been fine for 8 years i kind of don’t want to risk switching out. I torque to spec every time and don’t do hot wheel swaps so I ‘should’ be ok lol.

I don’t consider studs a wear item if they are properly cared for. But...the consequences of a failure are high which is losing a wheel at high speeds. There’s no way to tell if they will fail until they fail.

So preventive replacement mitigates improper care.
