18x5.5 rear wheel spacing issues. Wheel came with a 1/2" billet pulley spacer. Mounted, the wheel if off center towards the brake side approx 1/2". Appears to need a longer pulley side axle spacer?

 

Put your wheel on the axle with no spacers, put the brake caliper on the rotor and pull it tight to the swing arm, now measure for your spacers
