Hey guys, with all my Autox tire changes I've been braking alot of the stock wheel studs. Any ones you think might work better for me?

 

check out the arp studs...i have them on my car and i do a lot of track days and i've had no issues with them

 

ARP studs are great and you can also get equal strength studs from Summit Racing in Ohio. I think they are the same as the Evo. Get fairly long ones so you can put on spacers if you want to move the tire out to the edge of the fenders.

The stock studs will eventually break. We torque ours to 80#'s.

 

Thanks guys, I'll check thos out

Nismo has them too...

 

I broke 3 on one rim during a standard wheel swap. Breaking a stud is probably one of the most nerveracking experiences if you have never changed one before, lol..

 

I got my ARP studs from SPL. This is the only way to go for Hi Performance Cars on a track with R-compound tires

Agreed, I just bought some for my car.

 

Bump for a bunch of good guys, recommend picking them up here. Got my studs and lugs here

 

+1.

 

Consider replacing your front wheel bearings when you install the studs...if you have many track days/miles on the car...

 

Rear hubs too...

 

BTW: I have 2x new rear bearings available, as well as used front wheel bearing and a bunch of OEM wheel studs..some new/some used...

PM with offers as my 350Z is long gone..these are left over from my spares kit.

 

Wow, after 5+ years of autocrossing and track days with regular changes between street wheels and my autocross and track wheels, I have never broken a stud or stripped one or had a problem with lug nuts.

How are you removing them and better yet, putting them on? Impact wrench?

You should be tightening them with a torque wrench, never with an impact wrench. Also, at least once a year you need to put some anti-seize compound on the studs.

Better studs may be a cure but it sure seems you've got to be doing something else wrong to be regularly breaking studs.

 

I've never had a problem either with the Z, or with my old RX7. However, hearing these other guys makes me nervous. How tight do you torque your lug nuts Dave when you swap?

 

I have never broken one...but I don't take chances on the race track...

I certainly agree that if you have a real race prepped car then it's worth the extra insurance of having ARP or similar studs. With a street car where you're constantly changing wheels, you are automatically presented with the opportunity to inspect the studs, plus if there is a problem, that's when you're likely to break one and find it.


If corz is only autocrossing, he's not subjecting the studs to the kind of stresses that tracking and racing does. Broken studs should be rare IMO.

 

I broke a ton of them on my old 350z, almost one a weekend. I ended up going with the NISMO studs on the front, never did put them on the rear. At that time though I changed from using a 4-way bar to just a socket, that severely cut down on the number of studs I broke. In fact I don't think I broke any of the rears after stopping using the 4-way bar.
