replacing studs

what is a reasonable number of track days, track miles, laps, or seasons to use a set of wheel studs. know they are a wear item but how much? every 2 seasons maybe or 20 track days?

You can probably get away with doing it every other season if you're doing 10 trackdays per season, but I feel more comfortable putting on a fresh set every spring before the season starts. I feel this way because 1) they see a lot of action with two wheel changes per track event, 2) it's not uncommon for them to fail or break when they're tired/stressed, 3) my 75mm TMS studs are on the car year-round, and are therefore exposed to road salt/sand/grime in the wintertime.

I just replaced mine after a full season. Just so you know... it was a big PITA.

Regarding your question, I would ask your vendor about the replacement frequency.

I had mine on for two seasons and one broke during a wheel change. It's going to be annual changes for me going forward.

Studs should be replaced every season if seeing regular track use.

I do mine yearly since it sees all four seasons....speaking of which, they are currently caked with salt

Depending on what Loctite you used, removing them can be INCREDIBLY annoying...I have messed up a few lug nuts in the process, so just make sure to change your lug nuts as well, or at least have extras.

I am currently on the Bimmerworld Premium Race Studs. They are a bit more expensive than the Turner ones. I've only used them on the street thus far, but I have swapped wheels A LOT over the past several months. They have been holding up very wheel, including with the use of an impact.

But in all honesty, it's a bit too early for me to say how their longevity is. So far, very pleased though!

would like opinions on macht snell or other brands that dont require loctite to install so easier removal. also not sure which ones but have seen hex head ones so can use ratchet to remove.

As others have said... Loctite basically glues the studs on the hub and breaking the bond takes a lot of work. Also, some double nuts may slip on the threads...

It's not impossible, just so you know what to expect. Get a long open-ended wrench would be my advice!

Turner studs have hex heads, but they are not designed to withstand the torque of removing the studs.

so the loctite they came with was the red right? sounds like fun. any other hints. torch?

I believe so. Large arm muscles definitely help!

If you blast them on with an impact and consistently over torque the nut then maybe 6 months. If you take care of them, properly torque them, don't bang the wheels on the threads and start the nuts by hand then they last much longer.

I got 2 years out of the Vorshlag 75mm studs before replacing but won't do that again. I don't remember those being a total whore to get out.

I would immediately replace the studs on a corner if some nuts got loose on track. Especially the studs where the nut was still tight because they just took a beating.

Sorry to sidetrack this thread a little bit, but is there an advantage to studs over lugs beyond the ease of changing wheels?

Thanks.

No but it gets really old fighting with the front wheels all the time. Plus, you still have to change out the more expensive lugs just as often as the studs if you track your car.

So if I've never tracked my car and it currently has 95k miles on it and likely is on the original lugs, should those be replaced?

No its the constant taking on and off that we do with track wheels and the pretty ridiculous stresses we put on the lug bolts/studs on the track that causes them to stretch/fatigue. On a street car that only sees the lugs off when doing tire changes, I wouldn't sweat it.

If I plan to start tracking my car 8-15 days a season is it worth converting over, or just wait till I have dedicated track wheels?

As an example, my original front brake pads on my 330 lasted 65k miles. I'm lucky to get 1k miles from track pads. Your wheel fastners are seeing a lot more abuse and MUCH higher lateral loads. Probably 1G+ especially in cars with modified suspensions and r-comp tires.

Which is why if you are a beginner or intermediate...you can get away with longer intervals for wheel fasteners. IMO, as everyone has said...a year is about the limit. Anything longer could get ugly. It is highly likely that the wheel fasteners will last longer but why chance it. Imagine a wheel falling off at the limit of grip in a fast sweeper...

I'd wait till you see what wheels you're going to be running and if you need spacers, because you'll need longer studs/bolts if you are using spacers.
