How funcitonal do you want to keep your car as a functional daily driver to seat 4-5 people?
as stated spare tire and everythign else, (use towing service on insurance or a small air pump and patch kit). remove seats, head liner, internal plastic peices, carpet, etc. how extreme do you want to go?
Can get a small light weight AGM battery and aluminium battery bracket (does the battery stuff for the ST fit the non ST's).
You can start scraping sound deadening material off. remove the speakers (or some of the speakers and reduce the size of others)... again how crazy do you want to go?
