Come on now...
I like hub centered Budd wheels myself, but find these Dayton adapters interesting and unique.
And I disagree with your first two points:
1. Dayton wheels will run true if you take the extra minute or two to true them up as you tighten the clamps, it's not that hard...
2. They take much less stud torque.
A typical stud centered Budd wheel takes 450-500 ft.-lb.
A Dayton wheel with 3/4" studs takes 200-260 ft.-lb. Then given that our Dayton wheel adapters have 5/8" studs they take even less torque.
-- Can I give you $0.01 change back on your 2 cents?
