If you consider the studs as the points of a compass... take out east and you only have N, S & W... all of which are basically to the left had side of the vertical... almost half of "one side" of clamping has gone for load bearing!
Manufacturers do put 5 wheel studs on cars for a reason not just cos they like spending 25% extra!
Perhaps the term "Clamping" was misleading and should have been "Lateral Load Bearing"...Fil
