Hm, I'm conflicted is it the spring I change out or shocks and struts?Best we can tell is stock for the AWD Turbo is 2.94/4.11 per AutoEXE. CS has different numbers but they seem a bit exaggerated to me so I'm not sure if they're accurate.
So you're running them now? These improvements you note are before you changed the tires or including the tires?
Adjustable sway bar links are definitely required if you care about ride quality. Don't skip them.

I might go with coilovers but ask Ceika or Cygnus to make it comfort set up. The valving, spring rates and all will be softer ride
