I ran into this post from a couple of years back, thought some may want to know specific part #'s of RS6 pieces

RS 6 F&R Bumper, Side Skirt, Bi-Xenon, Wheel, Exhaust & Carbon Trim Part #'s + ETKA
This list below was created 3/05 and is no longer updated. The dealer list price for many of these items has probably increased due to the limited production of the RS 6. This list does not include paint or labor. (Always confirm with your dealer before ordering).
