Got the axle centered and threw the wheels on to check the accuracy. Turns out they go on with only millimeters clearance between the wheel rim and the shock absorber bracket. These are the FFR 17 X 10.5 Halibrand replica wheels on a fox length axle.

So I'm uncomfortable with this kind of clearance and thinking I need different wheels.
