autoexe sells a spring kit that will give you a 30mm drop. I am fairly sure there is another kit or two available for our car already. the autoexe kit is 365 at corksport.com but I seem to remember there is a site sponsor that sells autoexe as well. either streetunit or mazda3online, look around they exist but I have yet to read a review of anyone who has used them, so drop at your own risk.... for now.
