I had CC plates installed a few weeks ago, they did a horrible job, I had to get my money back and take it somewhere else (posted thread and pics about this). The second shop did a great job but I'm starting to notice a knocking sound from the passenger side plate. I know the sounds my car makes and I know it has to be a plate issue. I really don't want to take it to the shop again so I'm posting in hopes that this is something I can look into myself (not a total noob, I've done headers and much harder projects). Only thing is I don't have impact wrench. Could this be a spacer issue? it only knocks on bumps and dips in the road
