The wait is around 8 weeks I think however could be as low as 3 depending on what they have already in terms of rims I beleive.
This obviously depends on the sizes you want. I wanted a gun metal centre with the polished lip but they only do black, gold, silver and pewter so I am getting silver and will re do them myself.
The outer are normally anadised but you can get them dipped and then polished. But I think i will probably change my to stainless outers when i re do the centres.
I reckon the silvers would be a safe bet on yours though
