I read somewhere that someone took Gen 4 brake setup and retrofitted them (I am assuming front only?) on to Gen 3 chassis? Does anyone know if this is a direct bolt on, and will stock Gen 3 wheels fit? I have heard of other brake upgrades to Gen 3, but was told that when this was done, the stock wheels would no longer fit the upgraded discs. I would like to upgrade brake performance, but am not yet ready to get a whole set of 17" wheels and tires.
