Im about to bag and body my 91 iszuz on 18s or 20s. i have the 18s already on 225 45 18s. i work at a shop so tools are no problem. this is my first isuzu. what kind of problems can i plan on. And how difficult is it to get the front all the way down?

the radious arms are a pain in the ass there are a few things that you can do to take care of that. The front is no problem as long as you "Z" the frame SFBD or TRAD body drop

yea the radius arms do suck. you will have to notch the lowers to. zin the frame pretty easy to id post u pick of my front setup on 20s with 255/35/20 tires but dont no how to post em on here lol. as 4 the body drop, havent went that rout yet when u do it post some pick so i can see if its goin to be a pain.
