Well I have the 12" touring setup that I am installing on a 4th gen rear. I installed the caliper brackets and when I mounted the caliper and rotor, the calipers bolt holes were about 1/2"-3/4" away from the caliper bracket. If I pulled the caliper toward the bracket using the bolt it just clampled down on the rotor and wouldn't let it turn freely. So was I supposed to get some spacers to go inbetween to take up that extra space or what seems to be the problem?

Thanks
