Shiporu's right about cup joints, as you'll need them eventually, but the stock ones will do. They will eventually will break, but it'll take a long time. The 6 cell won't burn out anything, but your servo will stutter, like SEs. I read over at atomic mods that the reason it does this is that the servo is correcting itself and is going too far. A tap of the throttle gets rid of it, but I have not heard of anything frying with 6 cells. I would suggest if you have a Dremel to mount the cells in your bumper if possible. I did it in my skyline, and it fits barely. This will put more weight over the rear end and will not interfere with any moving parts, so long as you tape the wires away from anything bad. It works well for me!
