There's really no advantage performance wise to have the car so low, and to do it well requires so much extra investment (i.e. full coilovers with an adjustable lower mount). Shortened Konis and Ground Controls, when set with proper corner weights at a moderate drop, and aligned well, will perform just lovely. It's only when you get into super track-specific setups that you would really need the car lower, or of course if you just have to be "tuckin tire" or some nonsense.
