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.

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

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.

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.

Y2A, I used an excel sheet and put
name - lowering frong - lowering rear - spring rate - part number - special instructions

http://www.7thgencivic.com/forums/faq.php?faq=susp_faq#faq_susp_faq_q3

I can send you the file if you want to use it to make an FAQ.
Yes that'd be great! Send the file to my email at as1anmafia@yahoo.com :)

Can the mods/admin sticky this thread? I'm sure it can be pretty helpful to those looking for suspension mods :thumbsup:

The advertised drop for H & R is 1.4 front and 1.3 rear. After having the springs for 2 years and with a sound system its more like 1.4 front and 1.7 rear. This seems to be the proper drop with or without sound system. Sound system only add about 100LB. A friend has eibach pro and no sound system, the drop is identical to mine. The big thing that I noticed is that my rear tires seems like it is a bit covered at the top by the wheel well.
