As with the SB100 process, knowledge is your best friend. Read, learn and understand the process as best you can from posts here in advance. If you do you have a chance to make recommendations to the DMV agents and to point out to the CHP you have the FFR assigned ID on the frame. I dogged both a misinformed DMV agent and after a discussion with the CHP officer, having the FFR chassis number assigned as my VIN. Although I registered my car in 2014, I would suspect not much has changed with those behind the counter.
