What I don't understand is these brackets were made for the KR2S and I
bought 'em.
I thought I'd followed the plans / instructions.

I would do as Larry H recommends. If you find that you have a significant
angle under the head of the bolts or the nuts, you can buy self aligning
washers, which is a dome shaped washer that fits into a dish shaped washer that
will allow for an even load on the bolt head even if the holes are at a bit of
an angle. You can see the same repair on the gear legs on the GlasAir there at
LAM, as I did the same repair on it to fix the alignment several years ago.

Jeb,
What the varieze and longeze guys do to set the axle where they want them is
mix up flox, which is resin and cotton fibers mixed together to fill between
the bottom of the landing gear and the inboard end of the wheel axle where it
bolts to the fiberglass landing gear. Rough sand the landing gear for adhesion
of course and the bottom line is you are making a resin/flox wedge. Be sure to
paint pure resin on the landing gear before adding the flox mixture. Personally
I would put the current bolts in loosely, set the angle I wanted on the axle
then fill behind it with the flox mixture and let it cure. The flox mixture is
considered structural in this case.
An alternative is find some Cessna pre-made wedges that are used on those
certified aircraft to set the axles at the correct angle.
I personally would not make changes at the spar mounting bracket.

24 years ago I was in Austin, Tx building my KR2S. I drove to Arkansas for a
gathering and met Jeff Scott, which resulted in my move to Los Alamos.
Anyway looong time ago, I don't recall exactly how I mounted my main gear legs
and brackets. But now I notice that the tires are wearing badly on the
outboard sides
I always thought the weight of the KR would make the axles parallel to the
ground, but
nope, they're angled about 10-15 degrees - causing the wear. (?)
what? do I have to shim the bottom of the leg under the bracket?
Bye the way, I think I've got the thrust thing worked out, today, I did a high
speed test,
got it up to 55 mph and stopped it before last taxi way, less than half the
runway more like 3/8.
I think the issue was a plug wire not making good contact in the dist cap.
