Keep in mind that the SVT skirts are different from the older SE skirts. Does your car have any kind of rocker panel clading on it now? I don't remember if it was 99 or 00, but eventually the SE only had the skirts as an option and then finally not available at all.
For what it is worth, I think that the SVT skirts look out of place on the non SVT because they really need the lower front and rear bumper to go along with it. The lower SVT skirts just don't line up well otherwise.
If your car has no skirts on it now, have a good look at the early SE skirts before you make up your mind.
