Sounds like you might need to extend your brake lines and deff. check the drive shaft angles with that but thats all stuff you can figure out when you start or with some more searching. I'm personally against RC but that's just my opion (and yes, I'm going ot say it), I just dont like their products, it comes with a life time warrenty, but your going to have to use that warrenty no matter how hard you wheel. But the tire size to lift hight is pretty good.
