The absolute best thing you can do is buy a pair of G-Force extended rear hubs for a Banshee. This way you have a more common bolt pattern (4X115) and you can switch to 9" rear wheels so you have more choices in tires.
This will work providing the rear axle is a 24 spline & not a 26 spline. If it is 26, then OEM or aftermarket hubs for the LTZ-400 or LTR-450 will work. The 4x110 bolt pattern is pretty common.
