probably a good call. the only reason I know anything about this is because I have had a steel bumper chrome plated and it's a process. I have heard nothing but good things about silver contacts but have never had a high end mod with them and like a lot of things in life the difference you get isn't worth the hassle for the minimal gain. If you have the cash buy a Panzer Mod, i believe it has silver contacts and hit like a truck. I'm ok with my mods hitting like a mid sized sedan as I can't tell enough of a difference
