The Mugen 26mm sway bar is great, we've only ever used them on one of our cars, but it made a huge difference, though it is now a lot easier for the back end to kick out on you. As far as the camber goes, we have found that more camber is better, up until a certain point, where you start breaking axles every couple of races. Camber settings will change depending on ride height, so you'll need to do your own, and do a little trial and error, and figure out what you like.
