[puts flame suit on, this is gonna get bad...]

ok man, I will try to answer this as politely as possible, please do not get offended by my post...

If you need to lift it, DON'T DO IT. Box, bubble and big bodies can do it, I've gotten used to it, BUT COMPACT SEDANS CAN'T PULL IT OFF, NO MATTER WHAT YOU SAY OR DO! You can probably fit some 19s on there with rubber band tires and pulling the plastic fenders wells out. I would recommend getting some lowering springs just because that big of wheels will add ride height, and we aren't mudding or dirty donkin' here... 20's will most likely require a lot of work with out making it horrendously stupid. If you do it, do it right even though it will cost $$$$$$$, and DON'T FUCKING LIFT IT!!!!!
