I ordered a set from "Ultimate Pedals"
http://www.ultimatepedals.com. I'll post pics when I put them on. Super heavy duty aluminum with a variety of surface options and custom etching as an option as well. Mine are the frosted anti-slip style with a top left heel-toe gas pedal, with "335i" in BMW style font.
They are pretty expensive on his website, but he sells them for 1/2 price on ebay:
