If you are looking for an alternative to taking your Roadster to the Torrance service center, Javier, a former Tesla service technician, has set up his own shop in Gardena (a mile or so away from Space X) and can do Roadster annual services and other repairs (including fixing PEMs, suspensions, etc). He also installed the new rotors I got from the group buy on here two years ago. He said he can also do non-warranty things like install lowering springs or after-market parts on Model S, X or 3's. Here's his info:
