You should also invest in a sprocket adapter. Costs more but usually worth it. Saves you allot of trouble compared to those stock sprocket mounts. Sprocket adapters clamp up directly to the hub as opposed to clamping down on the spokes. Sprocket adapters can range between $25 to $70. The $25 adapter I got is basically three parts that hook up to the hub via hose clamp to make it easier to center the sprocket. To make leveling my sprocket easier I was thinking of going with metal 1 to 2 inch cylindrical spacers for the bolts so I wont need to use the rag joints that come with the kit & would be way less stress on my spokes.
