It really all depends. 400/800 was great for street/track use but when you migrate up to a mostly track vehicle and a square track setup (like I hope to be running soon) you want to have a somewhat even spring distribution. However, you still want the fronts to be a little less stiff because if not you will understeer like a civic. Fred from ER is running a square setup on his track car and 900/1000 I think. A little extreme for us but they JUST drive that car on the track.
