Aren't 5 point harness's more dangerous anyways if you don't have a roll cage?
Something along the lines that if if roll your car without a cage, it will cave the top in and crush your head because the harness is keeping you upright, while a stock belt lets you lean foward. Just something to think about, may just be a rumor. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/notify.gif" border="0" valign="absmiddle" alt=':notify:'>
