>>>What facts? I see (mis)interpretations and opinions. I see no facts other than some lugs have failed and some have not!<<<
Cdlena, quite a bit is known about fasteners. This is not new stuff and S2000s obey the same laws of Physics as any other car. Some valid references were provided to the interested reader for his pursuit. Feel free to check them out! Always torque fasteners as instructed under the described conditions such as dry. lube, stages, etc. I took the time to learn everything I could about wheel fastening after I had a wheel come off at Lime Rock. I even have it on video. I never want that to happen again to me and it's easy and cheap to see that through. Another variable is the wheels themselves. For various reasons some lose or hold torque better than others. If stuff keeps breaking, don't keep doing the same thing. 'Smyroad, if you take some pics of the broken studs we can even do a postmortem to see what happened. For example we can discover if the tension was too high or the seating surface friction too high or whatever.

The lug is the threaded portion, it is not plated or treated.. the nut is the chrome piece. There is never any reason to lubricate the nut.. IMO that is what makes these numbers vary so much; it is talking about 'lubrication of the bearing surface'. A bit of anti-seize on the threads means little except elimination of corrosion.
