I have been given the following data. The source asked to stay anonymous, but the numbers are real.

Front springs
2000-2001 49.8 N/mm
2002-2003 43.6 N/mm
2004 46.6 N/mm

Rear springs
2000-2001 46.7 N/mm
2002-2004 47.9 N/mm

Front Swaybar (diam x wall in mm)
2000-2001 28.2 x 5
2002-2004 26.5 x 4.5

Rear Swaybar (diam x wall in mm)
2000-2001 27.2 x 5.3
2002-2004 25.4 x 4.5

So there you have it

 

Sweet.

 

I don't see how this can be acurate, because Honda quite clearly stated that rear spring rates were decreased 10%.

So either the source is mistaken, Honda lied, or Honda changed things mid-stream..

 

Thanks! There was always some question about MY02-03 spring rates. I am surprised that the MY00-01 is considered more oversteer prone seeing as how it had stiffer front springs and stiffer front and rear swaybars?


P.S. Anybody want to volunteer and have the spring conversion rate to lbs/inch handy?

PPS. Anybody willing to sell me their MY00-01 front sway bar?

 

Interesting. The spring rates are really quite a bit different than the previous wisdom of this board. Here's what I have from an old tech data sheet from Honda:

the source is legit, I assure you.

 

Just wondering why your source wishes to be anonymous. Does it matter if we know who he or she is?

 

it doesn't matter who it is. and the fact that the person chose to be anonymous should hint at its source. thats all I'm saying.

if you want to talk facts feel free, otherwise stfu.

 

remember swaybars are part of the spring rate.

They went to 2.1% stiffer springs, but they went to a 6.1% smaller diam bar with a 10% thinner wall.

Throw those numbers in a marketing blender and you'll probably come close to 10%

 

I'll add some more to the confusion.

A year and a half ago I had all my stock springs measured. At 1" of spring compression the front rate was 211 lb/in (37.0 N/mm) and the rears were 278 lb/in (48.7 N/mm).

We measured every 1/4", and those measurements showed the springs to be slightly progressive. So, if you extrapolate the curves linearly (the plots I have showed the rate increse to be linear) to 3" of compression (I pulled this number out of my arse, not really sure what the compression is at ride height) I get:
Ft: 235 lb/in (41.2 N/mm)
Rr: 310 lb/in (54.3 N/mm)

Don't know if this helps or not, but that's my hard data.
