I agree with yoshi. 2"+ is way too much. You can easily drop 2" if your just looking at the wheel well but look at the ground clearance up front and you'll see you can't drop it that much w/out scraping on everything.
I think s14's with the front lip have even less clearance up front <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>
