Questions on lowering a Yukon

[2011yukon]

First of I would like to say that I'm new to the forum but lurked for a while. There seems to be a good deal of info from people here which is why I joined. I have a few questions I want to get some help with. I am debating on putting some 24s with 305 30 24 on my Yukon. I am also wanting to do a 2/3 drop. My first question is what issues will I have with this setup as far as rubbing or anything else you can think of? I see that a lot of people on here have this setup and some rub and some don't. Second question is I'll be towing occasionally so should I just stay away from lowering altogether. I am completely new to this so any help will greatly be appreciated. Oh ya my Yukon is a 2011 without auto ride.

1. It really depends on the rims and the offset. Not so much as the how low.

2. lowering is fine with towing, just get helper bags.
