I know what means higher spring rates, but what happen if I use higher spring rate springs?

Talking about using 88-91 CRX springs on a del Sol.

Tein CRX are rated 268 front and 123 rear, and 92-95 EG, including del Sol, are 212 fron and 140 rear.

What it implies in terms of driving, handling, etc?
why is that? Is the CRX heavier than the 92-95?

andytheLSowner

the front will sit a lot higher than the rear of the car

Tyson

at spring rates that low, it wont matter what they publish.

it MAY (probably) be at different height simply because theyre made for a different car.

The Definition of Spring Rate and Load Rate | EATON Detroit Spring

This explains it beautifully..

Tyson

makes no sense and quite frankly is irrelevant.

redlinetuning

Why is it irrelevant? Obviously you don't understand the physics of it.

TPB

Because it fails to acknowledge spring length or perch height which can vary considerably.

SpeedRacerEX-R

It explains the difference between spring load and spring rate. A lower spring rate won't determine the ride height.

redlinetuning

Perch height will only affect the spring if there is preload, even then, it doesn't change the spring load capacity or rate. Now if you were to take a spring and cut it, yes, it would affect the rate and spring load because you change the physical characteristics of the spring.

redlinetuning

Yes it will. Two 7" springs, one with 250# rate and another 500# same car same motor, the 500# will sit higher even at the same perch height because the 500# will have less compression than the 250# spring

TPB

To answer the OP's question, if the springs you are comparing are the same length, the car will experience similar handling characteristics as before (maybe a little more understeer) although the perception of ride may be very slightly stiffer. Those spring rates are not a large enough increase to worry about.

Asking because I am building a 93 del Sol with H2B (H22 & GSR tranny).

A local is selling Tein S.tech for 88-91 CRX new for $100 (old stock). If I use those will it ride well or not.

It will be more for street, not dayly driving, and some drag. Not too serius drag by now but I want low 11's and maybe high 10's. And also in the future maybe try some slicks.

Always I say not serius drag until I start going to the track!

gmcuajo1

Ok. I read the explanation of the difference between spring rate and load rate which I already understand.

But my question is, what are the effects on these two particular springs on the each car, the 92-95 civic, 93-97 del Sol (specially 93 del Sol which the one I have) and 94-01 integra? For those three models their suspension design and setup is very similar and thus the recommended spring is similar, if not the same.

Is the CRX spring longer or shorter?
Does the CRX weights more or less?
Is the CRX weight distribution diffetent? Does it's response is different?

Tyson

yes, geometry is mostly the same. and the del sol definitely weighs more than a crx. wheel bases are also different.

but none of that really matters when it comes to reading into what TEIN figured what would be an improvement over OEM. or heck even trying to read into what Honda designed into the rates.

like i said before, TEIN springs are generally very soft, pretty much like OEM anyway. and at that soft of a spring, it really doesnt matter what the differences are.

would the springs made for a crx fit and make a difference in your del sol? sure. will it be better? um, who knows, thats really up to you.

will it change ride height? sure, theyre probably made to drop a CRX 1" or so, and still be soft. on a del sol? not sure what the net effect of the difference of chassis and engine swap. you wont know until you try.

gmcuajo1

Thanks for your reply!
Don't take me wrong, but you just don't answer anything and leave everything as a guess. Is the same as don't giving any answer and summarize: "try it and let us know".

If they are the same geometry, meaning fitment and length, definitely the car front will sit higher than the rear. Taking into account the H22 weights more than a B-series it may end being level.

Spring rates isn't "rocket science". If you can elaborate a bit more will be better.

would the springs made for a crx fit and make a difference in your del sol? sure.

Sure? What kind of difference?

Tyson

meh.

good luck.

Tks

speedjunkie_g35

What in the 8th mile?? Def too soft for any type of track conditions. 350/350 was a great for a dd street setup.
