If your dust shield is too small for the wheel rings these handle little extension bracket will allow you to extend the bracket by up to 2".  You can flip them to slide and adjust length or mount direct in the holes.  Also works great if you need to custom bend or fab up brackets to attach to our rings.  
 
*Does not include bolts/hardware, each wheel ring installation is slightly different.  Installation is completed by self tapping or bolting the brackets to the dust shield or other mounting points, sometimes modificaiton of the brackets may be required for certain applications, test fit inside your rim and the caliper before installing to ensure full clearance.  Sometimes large brake systems may require the rings be installed on the inner side of the brake system not around the rotor itself.*
