I am working on putting a JL8 brakes on the front of my camaro but when I put the rotor on, the caliper will not gone unless I put washers behind the rotor. My question, is it safe to use washers behind the rotor so it can come out approximately 1/16 of a inch. I am using drum hubs on disc spindles. I was thinking I could use a stainlees steel circular saw blade and trim in so that it would fit inside of the rotor; that way the measurement would be consistant all the way around the hub. Not sure though, it may be to flimsy. Any suggestions are welcome and thanks in advance.
