What are your plans for the vehicle? If it's never going to leave the road there is no reason to lift it.
Don't because once you start it never ends. Any details on your 4runner?
Not sure if yours came stock with 225 size tires but i just went from 225's to 265's on my 15" rims and i LOVE the look. Added about an inch of height and they stick out from the wheel wells real nice. Take a look. Also i added the bug deflector and window visors. I feel it adds a nice clean touch to any of these 4rs.
