Typically, teams press fit bearing, as opposed to welding them.

So you do want to put your smaller wheels farther to the outside, to widen your wheelbase? Putting them in the same spot you would put an 8in wheel would be pointless, I am assuming, because the wheel base would be the same, but you wouldn't get better speed?

And what is "press fitting"? Could you elaborate.
