I'm thinking about getting my front rotors polished from classic components in California.What you guys think?

What are you getting polished? I could see polishing alloy rotor carriers, but the rotors themselves will function much better with a slightly rough surface. Polishing them would be a temporary thing anyway, as most good pads have a metallic content and would soon impress themselves on the polished surface, leaving marks.

I think if they are stockers, they will get gnarly looking afetr a while. I get a little rust spot on mine under the pads any time I leave the bike set after it gets wet. That area will get abraded down anyway as Danno said. The center which is painted black would look nice buy I would prolly not expect any unpainted surface to stay pristine for long. Just look at the outer edge of the waves on your rotor. It is unpainted. That is what a polished rotor is gonna look like after a year. If you ride on salty roads, even worse.
Perhaps chrome plate on the surface not contacted by the pads.

Polishing or chroming the swept surface of the rotors may lead to heat retention and premature warpage. These stock ZX-14 rotors are known for warping anyway because they are so thin. The same rotors used on C-14s are even more warp prone due to the extra weight they have to slow down. Chrome will probably not last anyway unless it's hard chrome like what they do on fork tubes, and that doesn't have a perfectly shiny, mirror-like finish because it needs to retain a small amount of oil to lubricate the seal and bed in to the bushings. Cast iron actually makes a better braking surface because it's porous and sheds heat well, but stainless has been getting better in recent years. Unless you plan on parking it permanently on a show podium, I would avoid polishing or chroming the rotors.
