Decide what kind of driving you want to do, then determine if you'd like to lower your car a bunch, or only slightly.

I've got the BAT kit & I'm lovin' it. No scraped bodywork or exhaust pipes, firm, confident handling, slightly lowered - only about an inch or so, still a great ride for long trips. If you have bad roads where you are, you might consider your stock springs or SVT springs and a set of struts with a lifetime warranty.
