THIS can be "vital".
Make sure the spacing is such that the pad is being "forced" to the rim's BRAKE TRACK at 90 degrees.
Too wide of spacing and the pads are angling down upon contact and get worse as force is applied.
When I switched to a set of Sun Rims M13II's on my hybrid, I had to add extra spacing to move the pads in.
I'm basically 1/2 thread shy of a full nut engagement on the studs. Not where I'd want, but I'll live with it.
Just one of the small pitfalls when doing things to a bike that it wasn't "quite" designed for.
