You will be fine with nothing else, but i would recommend at least an adj. panhard bar. Now depending on what springs you go with (pro kit or sportlines) you may want to consider some type of camber adjustment for the front. I have h&r supersports (theyre probably the lowest spring out there for our cars-about a 2.25" drop on mine) on mine with just an adj. panhard and its fine but i do have some wicked camber up front, i need to get camber plates soon. Thats just my .02, hope that helps
