Just because a person is educated doesn't mean they aren't a fucktard. Do what you said and add C'gussets for trail use and you will be fine for the most part. If your going to go 3" make sure it is a complete quality kit with some way of correcting the caster and recentering the axles otherwise it will drive like shit. I would recommend going 2 1/2 instead of 3 for a daily driver with 35's.
