Wheel rivet tightening specs and wheel rivet question

I recently bought 2 piece wheels that were missing some rivets. How tight should rivets be on a wheel? Should i torque it? Im going to be drifting my FC, I wouldnt want my wheels to fall off. Does anyone know where I can get rivets similar to the rivets on BBS wheels? Thanks.

Heres a pic of the wheel rivet.

Nat,

your chances of finding specs for a wheel might be slim. If you can give me the following info, I can provide you a tourqe spec for the nut/bolt combo that would give maximum strength for the combo. provided that all bolts are loosened and then retightend to the same tourqe (with locktite) it should be fine.

pm me with this data:

bolt size in inches, or millimeter ie: 1/4" 5/16" etc or 5mm 6mm etc
thread pitch (count) inch threads per inch, or metric pitch 1.25, 1.5, etc.
bolt material steel, stainless etc.

For those interested in the details:

http://www.rockcrawler.com/techrepor...rque/index.asp

"Where I work, the basic rule we use is that for structural applications, the fastener preload should be 67% of the yield strength. This value was chosen because a fastener (i.e. bolt) has a proof load value for each grade and diameter. The proof load is usually 90 percent of the yield strength. The proof load guarantees that the fastener will not permanently yield or stretch. If it did, you will loose your preload and the fastener will eventually fail or fall out."

I had my Kinesis 3 piece wheels re-finished and the guy said he torqued the bolts at 14 lbs, I had to re-torque it after a couple hundred miles after driving and did 14lbs again, so far no problems.

4mm
thread pitch count in cm 2.5
steel

What kind of material should I be using for maximum strength?

So lightly torque, loosen, then re torque to specs?

Do you drift by any chance? Im really concerned about the wheels being strong enough to withstand the g force of a drift. I know the load also goes to the lug and hub nuts but there would also be load on the bolts holding the face of the wheel together. Im pretty sure people drift with 3 piece wheels but If I have to go through the hassle of re torquing the bolts after drift sessions then It would not be worth using 3 piece wheels.

I do drift but not like how you would be doing it, truthfully I would not use 3 piece wheels for drifting but I did call the guy that did my wheels and he said that it does not matter what you do with the wheels, whether you drift, autocross, track or just drive it on the city streets, torque spec is still 14lbs.

He also said that if you go more than that you will have a high chance of ruining the wheel since most 3 piece wheels are made of aluminum.
