LOL, yeah, that's what I have heard from many others. Although some said why even relocate the perches? the mounting is what, one inch total? That comes out to 1/2 inch each side?
The only issue there, is it can cause premature wear on the spring eye bushings. Because one end will have downward pressure and the other end upward pressure from the spring being canted.
You can get replicated OEM wheels with different BS also, I think Specialty Wheels sells them.
