OEM SPRING RATES NE1 know?

sbmon · 04-12-2006, 08:32 PM

I was wondering what the oem spring rates are for the front and rear springs on the 2006 civic SI. I was wondering how they compare to the spring rates of some aftermarket coils.
Thank you for any information

Front 200 lbs. / inch
Rear 230 lbs. / inch

This means that the DX, LX, and EX Coupe rates are approximately:

Front 170~175 lbs. / inch
Rear 200 ~ 205 lbs. / inch

This is taking into account the Si front rates are listed by Honda as being 17-18% stiffer and the rears are 14-15% stiffer than regular Coupes.

Thank you Webby
That is excellent news. The s-tech teins I just ordered are less than 20% stiffer (stechs rates front=235 rears=274) than the oem coils on my si.
I would think the stock dampers should be up to the task of the slightly stiffer springs. Now has anyone had an alignment yet with the 06 si after a
1.5" drop? Was stock camber alignment adjustments enough to get the car back to a honda spec alignment?

from a few SI owners - they said they already noticed some tire wear after they lowered the car. It wasn't able to be adjusted enough without a camber kit. It has a "noticeable toe" in the rear especially

most vehicles are affected in the rear more than the front when lowering the vehicle.. Especially when lowering more than 1.0"

I might consider purchasing the SI springs/shocks in this case.

I'd actually am looking at putting the HFP struts/shocks on my S-techs, that seems like it would be a great combo!!

I'm purchasing Eibach prokit springs...what would everyone recommend regarding the struts?
