you should be fine, ive taken my VX out to offroad parks a couple of times stock and havent had any major problems (knock on wood!) only damage i have done was scuffing up the trim piece under the passenger door and putting a good sized scratch across one of the wheel center caps. both were a result of the same underwater rock that nobody else managed to hit (including me driving through it at least 6 other times that weekend)... so just bad luck.
not sure what the condition of my VX will be for this one, I *should* have 31x10.5 tires mounted on 15" rims with a 4" offset, which will stick them out of the wheel wells about 2-3" more than stock...and a 2" lift but thats not for sure yet, otherwise ill be stock with stock tires
