Thought maybe we should make a list of all aftermarket springs and coilovers made for the RSX, their drop and their spring rates, just like how evom.net did:

http://forums.evolutionm.net/showthread.php?t=66296

I'm just listing as many springs/coilovers I can think of for now, if you know their drop and spring rates, or to make corrections and additions, please reply to the thread and I'll update the list.

progressive springs don't have a spring rate. If you call the company they can provide you with the range. Prokit is usually around 20-25% stiffer and sportlines likes are 30-35% stiffer. Don't quote me on that.

Great, keep them coming guys! And does anyone know the conversion formula for lbs->k and vice versa? So there's a direct comparison between the springs, lbs vs lbs and k vs k.

Some general lbs to K conversions stolen from the evo post:
10k = 560lbs
9k = 504lbs
8k = 448lbs
7k = 392lbs
6k = 336lbs
5k = 280lbs
4k = 225lbs

Found the conversion factor: 0.0178579673228346
lbs to k, multiply lbs by 0.0178579673228346
k to lbs, divide k by 0.0178579673228346

:thumbsup: :thumbsup: :thumbsup:

I have H & R springs. I think they are prograssive and the drops are 1.3Front and 1.7Rears.
I don't know what the spring rate is but I am sure someone on this board knows.
Are you going by actual drop or advertised drop. Because the H&R are advertised at a 1.4 front 1.3 rear for the RSX.

Whatever H&R advertises, because actual drop may vary from car to car, because of sound system, and other factors.

Where are the spring rates coming from?? The Apexi N1 pro and Type -V's do not have the same spring rates. One is for race only, and the other is for street use.

The JIC rates change from time to time as well

From your fellow CRSX members that posted above, but like I said in my initial post, if you find the correct info, I'll correct the mistake, but for now I'm just going to leave ??? until someone knows for sure the right spring rates. Since the N1 specs aren't comparable to the other N1 coilovers (mugen, tein), they're ??? for now.
