Yes -- the chroming will add weight. The price isn't bad, I think I paid $125 a piece for a set of 17's I had done. What I might suggest instead is to look for either new Pro-Stars or a set of the Crager version which is steel and chrome already. I think new rims won't cost hardly any more and will be the way their supposed to be, and the Crager ones will be cheaper than what you're planning to do.
