you will have to use xrays tophats on the casters thats the only thing i wasnt too fond of but w/e. and a diff is a must have it calms the car down so much, b/c it has a ton of steering to begin with. and i may be taking out the center one way to get some braking in the front end, my setup now is almost stock except for removing rear sway, diff up front, and changed droop. so basically wat im tryin to say is i love the car, lol.
