If there is an ideal length to maximize strength, then why not just run that length stud all the time regardless of tread design?
i find this to be shocking... i knew about longer wheel studs long before ever working at a race shop... and considering you did NHRA platforms, i cant believe you've never noticed... im sure they had long studs...
anyway... if you look at any car wheel stud with an open backed lugnut (and o.e. wheels), there will be a length of thread past the back of the nut that is comprable to the width of the stud itself... and if you look at a capped lugnut compared to an open one, the extra length of the cap would clear that kind of overhang... so essentialy the cars are coming with an ideal lengthed wheelstud... and the threat isnt of the lugnut ripping off the threads, because the threads behind the nut will have no hinderance on its ability to hold on... as best as i can figure its a matter of load distribution and leverage...
a quick search on google found these Weapon-R
extended wheelstuds i'll have to figure out what the magic is now... but i do know its required equipment for drag strips and racetracks when a car is wearing slicks...
kid i used to hang with had to put some on his 337whp 91 sentra se-r... hehe... that car was silly fun
