Agreed, I have no quads and upper/lower ca's and still get some serious wheel hop, Im putting my quads back on. People remove quads mainly to fit bigger tires in the rear, Im going to see if I can fit my quads back in.
As for the front sway bar, I took mine out, it depends, if your going for handling, leave it in, if you want a drag style car definitally take it out, its much cooler. The front comes up 2x as high and twists a lot more. Very bouncy when you tap the gas.
