And chrome add a small bit of weight. The most simple and cheapest way to go would probably to have them High polished by a local chroming shop. I had it done to my RX8 wheels and they look like they are chromed except there is no chrome just high polished shine that I can make look even better with some TLC, here is a pic of the high polished wheels, cost me around $300 to have all 4 done here locally:
VERY nice! I'll try to find such a shop here on Cape Cod. Thanks!
