I <3 my F2..........
and as she sits currently....with the stock wheels and some additional painting...
the RS peices are expensive and super rare to find. Most people scrap the idea when they find out how much it takes to get them here and then have them installed.
the F2 is the more economical purchase....but don't think that buying it and installing it is cheap either. Comparatively speaking, it is, but it's still not free.
