with gas prices as unstable as they are these days, i would say yes its a bad move. particularly because its a 2wd, meaning your probably only wanting to lift it for the "off road" look.
dont let your friends get to you. theres nothing wrong with driving a stock 2wd. while all of them are diggin in the couch for gas money to feed their "manly" 4x4's...you'll be driving to vegas for a night on the town.
