A nice set kit will help you a lot in that "slammed" look. I helped a friend put some gc's and koni's in his jetta. We dropped it all the way down for pictures, and damn it was dumped. After he put his kit on, it was resting on the side skirts. Obviously you don't want to drive it this way.
Go for some more performance style springs/struts or coilovers, and just get a kit. That will give the low look, and drive nicely too. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
