This thread of course will be a work in progress and anyone that would has good information, facts, developments, or anything for that matter that this thread should include, please feel free to PM me or any other moderator to have the info. added to the thread.
Most of the information in here so far, is right out of our current FAQ thread that most people can't seem to go through before they post their questions. Now hopefully, with this thread right at the top of the page, hopefully anyone with a suspension related question will be able to get their answer here on their own.
Here is a list of useful links containing common knowledge about our MacPherson Strut suspension design...
02-04 RSX springs are not directly interchangeable with the 05-06 version of the RSX. Unless, you convert to the 05-06 shock bodies and hats.

[What is Progressive Spring Rate?]
Progressive rate springs are likely “all-in one” solutions. They are often used on performance aftermarket kits like Eibach or others, and they are good for daily performance street driving. They help you achieve the highest performance when driving hard, while providing a smooth, comfortable drive the rest of the time.
[What is Linear Spring Rate?]
Linear springs are more often used in drag racing, road racing, track and races that require a “high spring rate”, in which a constant spring rate is more important than a smooth ride. They are still popular because they are:
1. Easier to produce and can be made to lower a car beyond the point of progressive rate springs.
2. Easy to work with, because the spring rate never changes, allowing quick chassis set-up.
3. Inexpensive, allowing most race teams to use several different sets depending on track conditions
