Any detailed info on the difference in spring rate between base, WRX, and STI?

Hi guys My 2010 Impreza 2.5 has worn struts/tops and control arm/rear suspension bushings. I plan on keeping the car for a few more years and would like to upgrade some components to OEM WRX or STI parts. I'm not interested in making it a track car or lowering it alot. I just want to replace the worn base model parts with something better that will make the car feel more sporty. It's a daily driver so it needs to maintain decent ride quality. Here are my ideas/questions: Replace front lower control arms / rear links. It seems this is easier than pressing them out and not too expensive. Not really interesting in upgrading to urethane. Replace factory shocks and springs with OEM equivalent WRX or STI components. What are the differences in spring rates? Do they just swap in? Once the worn components are replaced I would like to upgrade the sway bars too.

I have a 2010 Impreza 2.5. I've had it for a few years and now that the suspension is starting to wear out i would like to look into upgrading it. What do I have to do to be able to post in the suspension forum?
