So far I've installed yellow fogs (and yellow vinyl on the foglights), and put some Michelin Pilot Sport A/S 3+ tires on. I also had the windows tinted as well. I just ordered a short throw shifter today for it, as the stock shifter is very tall, and has a very long throw. Only other plans for it at this point are mudflaps (because rally car!), and to put the roof rack from the ST on.
Something interesting I did not know, is the RS comes with an owners kit if you buy it new. It comes with a congratulations letter, some brochures and media, a DVD about the RS development, and a shift knob on a display base. Pics are below of the kit.
This is the day I got it.

Yellow Fogs installed!
