Why wouldn't you. What part do you think will fail? If you are driving like a crazy person of course things will fail stock or otherwise.
What stock components do you think will fail, other than the stock tie rod, that will leave you stranded?
It's all relative to where you are wheeling. I can only imagine how much of my Jeep would fail, if I tried going wheeling with guys the likes Of Mr. Blaine, Robert Yates or Wushaw. These are just the first guys to come to mind, i'm sure there are many more.
Lets say I had lockers ( I want them but I don't have them yet)
I could picture my control arms themselves being ruined, The control arm mounts being ruined. I doubt my stock axles are up to the task. I don't have Curry steering, I have ZJ stuff, I have no idea how that would fair.
Oh, my tires would pop (thats a personal mistake on my part)
I guess eventually if I continued to wheel where they wheel, I'd end up with a rig set up like theirs. I doubt they just spend money because they enjoy spending money.
In the case of this thread I agree with you guys, when you have 500 dollars to spend you can only do so much, so I like the responses and advice. I don't think a rig set up like that will have much luck out where they wheel though. I think it would be quite embarrassing actually.
