update:
Took the calipers off and gave them the best cleaning I could without doing a full rebuild. pumped the pistons out until I saw clean metal then took a tooth brush and simple green and q-tips with brake cleaner. re installed onto the forks and installed wheel without the shims. Im getting way less drag now. definitely acceptable for the purpose of this build. Justing waiting on a spacer to be machined and sent to me for the left side of the wheel then I can install rubber, steering stops, and headlight. Will be riding in no time!
