trust me bags ride real good with a decent set of shocks. the only hard part of the install is just notching the rear. and for the steering arm. other then that its pretty straight forward. you will want some 3inch dropped ibeam from DJM to help correct your suspensions alignment. and if you install it make sure you make enough room between bag and wheel/tire so you dont rub on it and need a new bag every week.
on the downside if the company that did your setup in the rear completely ****s it up then you get to redo it. the dumbasses at CR fabricatoins here in sac ****ed mine up so now the only peice of work they did thats staying is the notch in the rear.
but yea i vote bags. i wanna see more people out here with bagged rangers.
and its not that bad on bumpy roads. where i go to school a road can legally be dirt with gravel over it. so its not that bad. and for rims id say stay around 17s, i have 45 series on my 17s and havent bent a rim yet, even on some nasty potholes.
and also the guys at fbi can help alot. since they are a 15 minute drive for me i can go pick up stuff there. www.fbimini.com
thats their site. call them sometime and ask for victor, he has a bagged ranger and will help you with any questions you have.
