I guess for me it just doesn't make sense to get ARP wheel studs when all that same torque is passing through the little tiny hub studs. Those are on a smaller diameter, and they are MUCH smaller studs.
We aren't interested in Wheel studs for the strength of the stud in relation to torque being transmited, its so that the threads on the studs stop getting all gummed up from taking the wheel on and off. Not to mention having a longer stud which would allow more thread to be used and would add more clampping force.
