I just finished building my first RC12R5.2 and in the directions it includes 3 shims for the front wheels. In the picture it shows all three shims on first then the wheel with the flanged bearings in it and then the wheel nut. When I tighten the wheel nut down all the way the tire doesn't move freely at all. I was wondering if there is a specific way the shims have to go in. Example: 2 shims, wheel with bearing, 1 shim, wheel nut. Thanks
