How is it full of failure?

I can adjust my caster, camber, and toe, and Swift Spec-R's are a 1.5" drop and an insane quality spring that don't bind and absorb much more than your standard tein/espilir/eibach/skunk2 spring. Please enlighten me why coilovers are necessary on a daily driven S? I'll be waiting for a good while I'm sure.
