Thanks for the feed back.

^^^ Anything with lower spring rates than stock will be softer than stock, meaning "smoother ride" (Swift Sport machs are softer than stock giving you a smoother ride), but with softer springs you sacrifice performance.
Check out that link I just posted

Front: 283 Rear: 308
Now look through that list and look for a spring that has either the same numbers or LOWER numbers to get a softer spring.

2) I'm like 90% sure the H&R will lower the front just a hair more than the Eibachs will. The rear drop using both springs is about the same.
3) Both manufaturer's springs will not sag. If there is sag from using quality springs, it is normally caused by the rubber isolators taking a compression set.
Springs rates for the stock linear springs can not be compared to aftermarket progressive rate (non-linear) springs - especially when trying to determine ride quality "by the numbers". The spring rate on a non-linear spring is a function of how much it is compressed. A well designed progressive rate spring usaully means a smoother ride during "normal" driving and "firmer" feel during hard cornering.
Lots of discussion in this thread:
