The topic is an interesting thought for a min but when you sit back and look at it, its really an non-issue. Most performance car imported or gray import comes with the single lock nut on. I have been driving City with single lock nut without having any issue or felt any steering vibration. I think there are probably more important issues for you to consider than lock nuts.
Since you worry so much about wheel unbalance. You should invest in torque wrench. Every car has a specific torque pressure for their wheels nut and city wheel nut torque pressure is 80lbft.
All nut torque pressure must be equally torque. If either one nut is over or under tighten, that will cause imbalanced and will generate wear and tear issue on tires, wheel bearing brake pads and etc.
There is specific torque for nut... But it's not necessary to follow very closely. As long as they are tighten reasonably... There is no issue with vibration n other wear n tear issue.
Nothing to be worried. If your 80lbft is right, I think my nut is tighten around there.
If u didn't experience any extra vibration before n after using this setup, good for u.
I have never experience any vibration issue with hand tighten nut on wheels.
My main point is, introducing only 1 lock nut to each wheel, and 3 other ori nuts is not recommended as this heavier lock nut induce imbalance rotational force.
I'm just sharing my knowledge n experience. Even before installing these lock nuts, I had this concern, and the result didn't surprise me.
Blurjoey using splinedrive n it's lock nut, which I think their weight is the same or very very close. Therefore no vibration issue. Probably, can sifu blurjoey help measure the weight when doing tyre rotation then.
