Fellow NZ'er here, Kiwi

I own a 2006 Subaru Legacy (aka 'Liberty' for Australians) 2.0R - Non turbo and recently installed some King Springs for lowered suspension. The drop was approximately 30mm-35mm and car seems to sit at a reasonable height but I'm planning on going slightly lower. My first choice was to install a Tein kit however on the day there wasn't any stock, so I decided to go with the King set (rather impuslive buy). At present I'm finding the ride a little too 'bouncy' for my liking and did a bit of research and found H&R to be a respected spring but slightly more expensive.
Would the H&R kit be a significant improvement to the King spring kit? Are they known to provide a better ride (firmer and not bouncy) as opposed to how I find the Kings at the moment? I've been told the H&R kit may not lower the car alot, however I believe there are different kits I can select from - I'm looking for maybe a 40mm to 45mm drop.
What would your advice be on this, I will have to save up again for this and kind of regret buying the Kings

Your help will be much appreciated, first post and seen some awesome rides on here.
