Need help with lugs

ANMVQ

Ok guys ,

haven't found anything at a local wheel place or on line. The only option I was giving was extened wheel studs. But wont this effect me when I go back to the stock wheels for the winter?

I have Rennan C10 Blue lable wheels Front 20X8.5 +24 and Rear 20X10.5+45. problem is every few hundred miles my lugs are loose( only like 4 threads holding them on!) Is there a solution as far as lugs I can use? Any thoughts much appreciated. Thank you

BTW lugs I'm using are Muteki 32905N SR Series Neon Chrome 12mm x 1.25mm SR48 Open End Lug Nut Set, (Set of 20)

wat torque are you using? ive used that same SR48 on my weds. no issue after one-two cycles of re-torque after a short drive.

also make sure your wheel/lug taper area, and stud threads are free from any oils, anti-seize, sealants/wax.
i suggest you spray it down with rubbing alcohol,rc car motor spray, rc car nitro cleaner, any degreaser.

and why are you asking this at a 370Z wheel forum?

Thanx man !

80 FTLBS Is what the manual says I think , The last re-torque was done at a shop . An because I spend more time over here because there is more info here

oh i c

i use 85ft/lbs (snap-on torque wrench). 80ft/lbs can require MANY retorque unless you use the washer-type lugs. GL
you can get click-type torque wrenches pretty cheap... like $20-25 at tirerack. also check harbor freight.

just compare the torque with a known accurate torque wrench to make sure accuracy.

4 threads seem a bit bare IMO. However that shouldn't be the reason your lugs are coming loose. If take them off and brush off the coating on the lugs (they should be flaking after your first torque) that are in contact with the rim so you have a clean contact patch. That should help give you the most locking friction. But I would still look into longer studs because 4 thread engagements are worrisome.

i think wat he meant was the lugs were tightened full thread, but were backing out to the last 4 threads.

Yes sir, ..I get I good 10 turns by hand before I even grab the wrench, They are backing off to 4 threads.

I'm going to go by my auto store and pick up another tork stick 85 LBS. and see if that does it . Driving out to PA this weekend for a wedding and don't want to have to check them when I get there and get home.

i guess my other question is... is someone trying to kill you?

You can put 50mm studs (~10-7mm extended over stock). These will work with your aftermarket wheels giving you more thread engagement on your aftermarket wheels/lugs. You will also be able to refit your OEM wheels and OEM lug nuts with no clearance problems. Z1 sells them as do many other companies. I went with Z1.
