** Awaiting Further Info

I called H&R springs and was told "We dont keep that information available because most people just care about how much drop, and not every company measures spring rates the same". I'm not going to go into how springs are rated but I don't think this person has a clue.




If you have any requests just PM me or post here, and I will do all the research.
I'll update this post as more companys respond to my requests for information

Great info! I just got H&R Race Springs... how do they measure spring rate anyways? Maybe I can do it and tell you so you can add to your chart.

If its linear then you can either A> have someone do it. I know the Suspension place up the street from me did it for me (Where I got the Stock numbers from) check around where you live.
B> determine how many lbs it takes to compress one spring 1 inch. (amazingly simple isn't it?)

Added Goldline Springs.

Very nice list. Those Eibachs look awsome!!

Ashe,

Do you have time to compile a list of coilover spring rates? I'm in the market for those, and it would be really helpful. Thanks.

Added Coilovers

sticky'd!

Added FLT-A2 Info...
Also If anyone lives in the LA Area.. Ben Chen from JIC is looking for an xA to test fit an Exhaust, PM me for the info, First person wins :P

Added RS*R Downsprings

Does anyone know why the coilover spring rates have such dramatic differences between front and rear?

I believe it is because of two things...
First most coilovers (if not all) are designed for autosports of some type.
JDM Sports companies have a tendency for a Front end Bias (Springs Higher in front than rear)
USDM Sports companies have a tendency for rear end bias.
All of the coilovers listed are from JDM companies..

wow...the megan springs have a higher spring rate then all of the coilovers??? and the rear is WAY higher...i wonder if thats a good or bad thing in this case?

Springs can cause your car to act as if they are "Swaybars" i.e. the higher the spring rate the less lateral roll you notice on that end of the car... this will increase oversteer.
If thats good or bad is up to you..

Just removed my Hotchkis springs the other day in favor of the Eibach Sportline. I have to say - I could not be happier! Without any settling, they are already a half inch lower than the Hotchkis, front & rear. And, coupled with the TRD shocks & struts, the ride is awesome and far, far, far superior to the Hotchkis springs! The springs are available at the TireRack though they did not have them listed on their website (they might now). If you're interested and don't see them, just give them a call.

David -

has anybody tried the HKS coilovers or the HKS springs yet?

i ordered the megan springs... I don't know hwo they feel yet, haven't even recieved them yet... but they seem to be one of the best out there for the scions.. u know?

Hi guys, I am a little bit confuse regarding spring rate for tanabe DF210.

I have just called tanabe in california, they told me the rear is progressive. so which one is the right info???

is H&R stiffer than eibach and tanabe df210?


Thanks
Masri :pray:

Well the person I spoke to didn't mention the rear being Progressive, so I may have bad info from some fool. As for the H&R they wouldn't give me any info so I couldn't help you there....

To give people a prespective on ride comfort vs suspension stiffness, let me tell a story,

About 2 weeks ago I went for a test drive on one of the new C6 corvettes. This peticular version that I drove had the higher performance suspension package. Z-something or other. Anyways, that thing road like a dream compared to my stock RS1.0. I could barely feel the highway reflector bumps that are on our California highways. Unlike on my xA RS1.0. Man, and what's funny is, a friend of mine that road in mine, but also road in a stock xB, said the xB was even STIFFER. Man, that's just wrong..

I told the guy I was most impressed with how soft the suspenion was for how well it held in the turns. He was suprised because he thought the suspension was kinda stiff, and he owns a C5 Z06. Ha..

Anyways,
point being, this is the perfect example of, going stiffer doesn't mean going faster.

great sticky here!! but would like to find out more... me on an ist thinking of lowering my ride (yeah slam that ride!)... i find the stock ride is bit stiff..especially at the back... so which one of those springs u guys would recommend to have it lowered + comfort ride? will i have issues with running on this new springs and current dampers??

i am curious about the same thing... i know i will either get the tein s-techs or the goldlines.. definitely one of those 2. i know the stechs on a box yields great results... but i have yet to really been able to compare the drop of the 2 types of springs.

i think since i am a college student and i have to go over some pretty rough roads daily, im leaning more towards the tein s-techs.

any suggestions?

-jon

Where are the TRDs? No love for the factory option?

The Lower the Spring rate the softer the ride would be, however Shock/Struts make a huge differnce as well.
No response from TRD contacts about spring rate.

yeah.... cos from what i see those lowered springs are rated with higher spring constant (so by right stiffer).... dont want my wifey & kid to hit da roof at the rear....

BUT... maybe got to do with the shocks too i gess.. its a combined effect....

the progressive springs looks good....

after doing a little more research, i think ive decided to go with goldlines... the s-techs for xA's dont seem to drop it much at all... and practically all the reviews for them say something about wishing the drop were more. i know how that goes from my previous car, where i had to try 5 different suspension combos before i was satisfied.

the goldlines look like a much more aggressive drop

jon

Are the TRD springs for the xa and xb the exact same? If not will the trd-xb spring fit safely on the xa. I want to change my springs and give my trd's on my girl's xa

They will fit, prolly be pretty stiff and the drop wont be the same.

From TRD_Help@Toyota.com:

xA:
ft. = 160 lbs/inches rr. = 150 lbs/inches

xB:
ft. = 170 lbs/inches rr. = 150 lbs/inches


According to the Scion Web Site, the drop is 20mm (0.787"), but these are typically described as settling to a 1" - 1.1" drop, front and rear.

Finally.

It looks like Tanabe has made some changes to the NF210 springs. The original post has the drop listed at 1.3" front and 2.0" for the rear creating a "reversed rake" appearence. Tanabe now has the drop at 1.3" front and 1.0" rear. Spring rates has also changed slightly from 154 lbs/in to 157 lbs/in for the front. The rear spring rates has changed as well from 121 lbs/in to 123 lbs/in. Looks like an alternative to the Tein H-techs.

and pics of the Tanabe NF210 on an xA???

if its on stock rims that would be a major plus!!! if not thats fine

The TRD springs for xA have a 20mm drop, for xB a 30mm drop, but both are supposed to have the same spring rate? Can these be interchanged to get 30mm drop on the xA?

Nope.
Same spring rate with more weight makes the drop on xB's larger, you put the xB springs on and you will get the same drop as xA.
They are the exact same spring .
Personally I would,nt suggest any drop that caused your Lower Control Arm's to move beyond horizontal due to issues with steering and suspension Geometry

Nope.
They are the exact same spring .


Why the different part numbers, then?

I should clarify,I have a Friend who works as a mechanic at the dealer who told me when I was asking about the spring rate that having installed both there was no difference that him or the other mechanics could see, now if they have the same rate and are visually identical it goes to believe that they are the same. why different part numbers i dont know , maybe the same reason I was told that the tierod for the xA will not interchange with the echo even tho they are the exact same part. possibly so corporate can keep track of what cars the parts are being bought for.

Thanks for clarification.

Anyone know the H&R spring rates?

OK, if I go with the eibach sportline will I need a camber kit?

I believe it is because of two things...
First most coilovers (if not all) are designed for autosports of some type.
JDM Sports companies have a tendency for a Front end Bias (Springs Higher in front than rear)

Hi Ashe, despite very best of intentions and org. ability on your part I gotta note
one boner in this old posting of yours. It is what influenced me to spring for Tein Basics,
expecting some sort of AutoX ride wonders from Basics



First most coilovers (if not all) are designed for autosports of some type.
NONONONONONONONONONONo :P that is just not so.


I can def. state that Tein Springs plain or coilovered, as spec'd for A and B for USA by TeinUSA are -for the comfort and style seekers-. The Tein Basic Coilover. is cushy. And so will be the Tein Super Street (has the very same spring rates). Crank shut the SS bleed screw to simulate ha ha a stiff spring ride but that's a different thing really.

Knowing know what I know now the $$$ way, if we want something really a lot more slalom-capable we'd want more in the not-so-radical numbers by Megan racing.


And another thing: numbers do "lie" a bit because unless the spring compression tests are done at the same -point within the spring's range of compression then it's not a gonna correlate well with other makers testing other ways.-

That is again: The spring "test" listed above is not valid. It is just not that simple.


Teins as presently spec'd by Tein for our cars -are not sporty-.
(and this goes for all you have listed above at present, excepting say Megan Racing... the other springs just don't -measure different enuf to be called distinctive from stock. Ten and twenty percents do not make "oh wow how tight" differences in results here.

OEM are not so weak as we might think by trusting numbers. NO, truly, OEM springs are stiffer than TEIN for danged sure. Again, it must be because spring rate tests were not done to a standard by one company, or another, or any of them.

We are left with a table of spring "data" that isn't as much use as... Joe saying to Fred: "x is stiffer than y by my own same-day riding test."

ouch my head hurts now I need to re-think my choices....

Has anyone tried the DZ springs for the xA? The advertised drop is 2.25 in the rear.

Anyone have the Tanabe DF springs? Does the ride bounce considerably?

TRD makes the only spring that is actually cold rolled there is a huge diffrence in the manufacturing process compared to other springs. Hands down I do not car what spring rate or coilover rate another company claims if it isn't cold rolled it is junk. I know I will get flamed for stating the obvious truth but you get what you pay for if your a cruiser buy the cheap 2 inch drop springs and have fun if you care about handling and curvy roads buy the TRD springs and no others. even the tommy Kaira subaru was criticized by road and track because it didn't have cold rolled springed coilovers on it and they lost valuable laptime and he agreed he would never use anything but cold rolled springs on his cars again. I would bet any cold rolled performance spring will produce better laptimes than non cold rolled spring or coilovers for the Xb or Xa TRD is the only choice for cold rolled.

well i did some research on the megan racing springs and those are cold wounded steel so its not only trd

i was thinkin about this set up for my suspension
megan racing springs with trd shocks/strut
or the df210s with the trd shocks/struts

if anyone else has any other suggestions please leave them but im pretty set with the megan racing springs

im looking for a stiff ride

mainly im looking for suggestions with shocks/struts

anyone here know the rates on the progress springs offered by partshippers?
i have asked them, but no answer. i will post if i get one.

thanks

Good points.

Is Eibach cold-rolled ?

I was talking w/someone in suspenstion/alignment at a tire shop today, and he mentioned "dont get a spring drop at 2.0 inches, or more... because it will dramatically mess up your (camber.. or caster... I forget) ... and there are several other parts that will be needed in order to get your front tires aligned properly- or else your front tires will wear unevenly- which then in the long run will cost you more $$"

btw, i contacted progress about the rates. they said that they do not remember making springs of a different rate for partshippers, so those springs should also be 165 front and 175 rear.

Eibach is cold rolled.

Any info on Intrax spring rate, etc ???????

what about Ksport? They sound alright?

Yeah,Very nice list. Those Eibachs look awsome!!

Tein's sounds good

HI all I am deciding which springs to get for my scioin xa 2006

I drive everyday about 10 miles and weekends about 50miles. I am considering

Eibach Sportline
Tebabe df210
Teins T-tech
Goldlines.

Which one would you recommend? Which one will give you a nice drop and smooth drive?

Thank you so much

resurrecting an old string.

I have a good deal on a set of Tanabe TDF spring. They look a bit stiffer than stock, which is OK. ( the XA is pretty stiffly sprung already)
I'm more interested in the drop. What other changes do I need to make to the suspension? Can I still dial in the camber with a 2.0 drop in the front?

New member in search of answers.

thanks,

Phil

Where did you find the stock spring rate?

I've been running Goldlines on my 2006 xA since the start of 2006. I drive the car through New England winters. Last night as I pulled into my driveway, the car was making some weird sounds, and this morning in the cool light of day I see that both of my rear springs have just broken from too much rust causing them to fatigue.

So, Goldlines are not to be recommended if you're in the rust belt, they only lasted me 5 winters. Their paint chips and cracks away and lets all the salt in.

I'm not sure about the rust-proof-ness of all these other types of springs, but a friend at work is recommending the Eibachs because they are powdercoated.

I envy those of you who live in more temperate climates :)

I wouldn't be surprised if Eibach makes the TRD springs.
One thing to consider - Eibach has the longest warranty AND they designed their springs to work with the factory dampers.

I drove on mine for two years, year-round - one year on factory dampers & one year on Konis. Changing the dampers changes the ride. Factory gives a streetable ride. Konis give a very racy ride.

I recently switched to H&R Race springs - as far as I can tell, the only reputable brand with the highest rate. I can't just go to off-the-shelf race springs because ours are different diameters top-to-bottom. I learned this from Eibach tech.

The H&R's give a slightly stiffer ride, but not a huge difference. They are also now grey, and not red as they are usually pictured.

Forget about alignment worries. Our cars are strut front/beam rear. The alignment does not change significantly. A-arm suspension changes camber. Neither is adjustable from the factory. Only the front is adjustable if you insist with crash bolts, but NOT necessary.

Bottom line, for an appearance drop, use Eibach SportLines with factory dampers & you'll be set.
