Man, this is gonna post right below or above that
post on the HS civic maniacs.......
<sighs deeply>

I was unable to get satisfaction on my
84-87 CRX enthusiast site. I am hoping
people here can give some kinda general insight.

Background:
I go and rebuild my entire suspension, except for the
rear springs on my 87 CRX, the one on my sig. Everything
was slam worn out. I did upgrade to KYB shocks, and also
as the rubber bushings are hard to get, expensive, and
have to be ordered individually, I just ordered the "black"
polyurethane kit. The torsion bars were replaced with
used but confirmed to be OK ones off of a honda wagon.

So it turns out my rear springs (there are no front springs) they
go around the shocks, are totally fubar. The car sits about
1.3+ inches too low in the back. I want to preserve the original
ride geometry.

I found a place that has replacement springs. I don't know
what the original ones were. They said "stock" is "750 pounds",
"heavy duty" is 1250 pounds. I don't really know what that means.
I guess one is more stiff than the other.

My question is obviously which ones should I get. With those bushings
and shocks the car is riding as stiff as I would ever want a car
to drive on the road. But maybe the older springs failed because
with the upgraded shocks or something I need "heavy duty".

Can anybody give an insight into it. They're about $100 i could
not return them, and also, takes me all day to change them.

My gut tells me to buy the regular, 750 pounds.

 

The heavy duty spring are overload springs. So if you regularly carry heavy loads in the back of your car, they prevent the back end from sagging. Personally, I'd go with the standard springs.

 

Thanks. I will order the standard springs in the next day or so.

I really appreciate that help.

 

Go with your gut.

If not best buy a kidney belt.
