Left hand thread lugs - stay or go?
Something about rotational force was reason for LH as I understand. Maybe someone can expand on that.
It was a leftover from knock off rims. The large, single nut was always left hand thread on the left side of the car because the theory was that the rotational force of the wheel spinning could loosen the nut.
With a large, single knock off that might have some merit, but it was carried over to the smaller lugs that aren't at the center of the wheel by Mopar and a few others early on. There was an article on it somewhere that actually tested it, I forget where I saw it. Bottom line is, if the lug nuts are properly torqued it makes no difference at all. If the lugs are left loose, the RH thread lugs on the left side of the car can loosen further. But if you torque them properly, it's not an issue. And of course, no modern manufacturer uses LH lugs now, so there are millions of cars on the road with all RH threads.
It's far more likely that you, or someone else, will forget the LH threads and ruin them, and possibly the hubs, by breaking them off trying to turn them the wrong way. If some are already broken, I'd just replace them all with RH lugs and be done with it.
