16's are no prob and yes u can lift ur car shit honestly i always wanted to have a civic with 22's just to see how they look but...even tho ur car doesnt go slower that doesnt mean that ur performance wont change...ex. u cause an extra strain on ur motor just by getting bigger rims (not because of weight but height) also on ur underside i.e. suspension travel, and speed sensor ex.2 a blazer with 16 in. rims with 33 in. tires-the speedometer says 55 but u might be doing 60 or 65 (a true proven fact)...
