stud/lug nut conversion......

well after torquing a lug bolt to bmws 120nm it noticeably stretched the bolt, i panicked, so now my car is sat in the garage feeling rather sorry for itself, anyhow i decided to order these bits from turner....

https://www.turnermotorsport.com/htm..._ID=TWH9950B62

and these awesome lightweight race lock lug nuts

https://www.turnermotorsport.com/htm...ODUCT_ID=32876

well its cost me like $340 but its worth it....... i track my car about 10x per year!!

Yup, I did this for my car since I track a lot as well. Be sure to put some strong locktite on the studs (only the short end that goes into the hub! lol) and torque them down real good. Then torque on the wheels with your lug nuts. This will allow the studs and the locktite to bond better. No trackwork for at least a week after install. And keep checking torque on the lug nuts.
If you happen to take off any lugs, check each corresponding stud to make sure it's still very tight against the hub.

I personally went with Gorilla brand studs, and Spoon (JDM brand as well) lug nuts to match my wheels a bit.
Would've used my spare set of Volk extended duralug nuts, but I might be including them in the sale of my non-M fitment LE37's. Plus, the Volk lugs don't match my wheels as well as the Spoon lugs.

Have the exact setup except I have the longer R40 Kics.
I absolutely love this setup, the floating collars on the kics torque up much nicer than normal.

turner supply locktite with these bolts.......... they also specify 16ft lbs on the stud into the hub, should i still torque the nuts to bmw spec 120nm or less?

I'm surprised that the studs only require 16 ft.-lbs. of torque. Are you sure that's all it needs? Because 16 ft.-lbs. is only hand-tight =O

I torque the lug nuts to OE 87 ft.-lbs. spec. I sometimes just round up to 90. I check every 50 miles or so, or just whenever I check tire pressures, etc.

Correct; remember, all you are doing is tightening enough that they stay in place.
It's just a threaded rod in a hole.
It's not clamping anything.

Use enough locktite to coat all of the lower threads, but don't have it running off.

m-fanatic fyi.... found in the m3 section and aimed someone that torqued tms wheels studs as you did.

wait, you guys TORQUED wheel studs?! Do not do that, there is no surface with which hold the torque, you're just putting them in with the shank against the threads.

BMW wheel studs should only be installed with Loctite, and should be very mildly torqued, they should depend on the loctite (well, and the contact area between threads) to hold them in.

I have turner's as well...put a little bit of locktite on them and put each one in with minimal pressure. I have muteki SR48 lugs on and have had no problems whatsoever. You'll love them, especially if you take your wheels off enough cuz lug bolts simply suck

I didn't use a torque wrench for my studs, but they're definitely tighter than "by-hand" haha. My lug nuts though are 87-90 ft.-lbs. for sure

They do but not enough to properly coat the studs.

You guys are talking about two different thing. Torquing the studs into the hub is low torque, torquing the lug nuts onto the studs is the standard 88ft lb.

You really only need a drop or two of locktight.

hah well this car's my second experience with stud conversion, and from my first experience, I had some loose studs which made ticking sounds when driving. I even used locktite on those as well, albeit the "blue" lower-level ones because I didn't want the studs to be permanent.
So I've since been very particular about making sure the studs are tight before putting on any wheels or nuts.
For the M, since I'm tracking it exclusively and don't mind even if the studs are permanent, I used the "red" higher-level locktite and tightened the studs a little bit more than "by-hand".

I wouldn't say "a" drop, a drop or two is good. Really the studs are not so big to need too much more. One drop will actually cover one or two threads all the way round on a bolt that size.


You can use more, the negative is that if you ever need to remove it will be very difficult and you will be required to heat them to loosen, and then chase the threads.
