So I have the funds to finally do my birffs and all 4 rotors and I am collecting the tools I will need for the job. But I have a couple quick questions. -For the snap ring pliers do I need the internal or external pliers? -What is the alternate socket size for the Slee 54mm socket? -Did any of you bother with the fish scale to measure the resistance and can I borrow yours? I think that's it for now.
