*Variable Rate Springs
**Ground Control are adjustable height springs aka sleeve coilovers. They use Eibach race springs and customized spring rates can be ordered.

Springs sold as xB springs but are not listed on manufacturer's website:
Tanabe GF210
HKS SF5
Arospeed
(edit: for some yet unknown reason, these springs are not listed on the manufacturer's website. However, they do have a part numbers different from the ones on the website, suggesting that the information for the product is simply not posted)

Anyhow that was all the info I could find on the net about various products... if anyone can fill in the rest of the spring rates or some of the ?? that'd be great. I don't think I"m missing any springs which are not JDM imports... if anyone knows the JDM brands I'll try to find the info if you post them.

The list is sorted by MSRP of which I used whatever the manufacturers site posted or was selling the springs for. For springs which did not have a price (or their site was just plain ghetto... I positioned them according to where they fell in lowest actual market pricing in relation to all other springs). edit: grouped by drop then by MSRP. Makes for easier reading.

The application column denotes whether the spring was specifically made for the xB (and hence whether a seperate spring was made for the xA, or whether the spring was made to fit both). This may help in determining how much a spring is specifically tailored towards the xB.
It should be noted I did this primary by part number. Tanabe and RS*R are the only companies i know so far that definately makes separate springs for the xA and xB (Tein, Espelir and Intrax may possibly as well). Tein has different part numbers for their xA and xB springs, but the spring rate is the same (only the lowering height changed), which MAY indicate it is the same product with different part numbers. xA Espelir spring data has been hard to come by, though it does have a different product number (ditto with Intrax).
Progress Tech does not list the xA as an application, their springs are made only for the xB it seems. I'm unsure about TRDs... maybe a dealer here knows.
There are different models of the bB in Japan.. (FWD, AWD, etc). The bB most closely resembling ours is the NCP31.

You should be able to get more info than (progressive) if you get ahold of someone at the company.. Oh and multiply kg/mm by 55 to get Lbs/in2

uuuuhhhh kgmm is the name of the spring company...

added kg/mm

my df210's came in pink/purple not white

is it only you or are they all like that? I just went by the color on the website (which are white... )
anyone?? I know there's tons of you on this forum... at least 68 lol

uuuuhhhh kgmm is the name of the spring company...

~wC
It also stands for Kilograms per Millimeter, those pesky japanese don't always translate metric into American standards. I was giving him a bit of advice on translating spring rates. On a side note I noticed that if I converted a spring rate I had both Standard and Metric rates for from the metric rates it wouldn't always add up to what the standard said it was....

Great info in this thread. Thanks for starting it!

umm that's b/c 55 isn't the exact ratio... I think its 55.8... give me a sec I can probably figure the exact one

1 lbs = 0.4535924 Kg
1 in = 25.4 mm

1 lbs/in = .4535924/25.4 Kg/mm = .0178580 Kg/mm
(rounded... but I might have messed up the number of sig figs)

so inverted that would be

55.99741 lbs/in = 1 Kg/mm

hmm odd not what everyone else says to use... but I used to most precise conversion factors I could find.. a lot of places leave off at 1lbs = .454 Kg or 1 lbs = .453 Kg or use 1/2.2 lbs/in = 1 Kg...

that should account for most of your error... try using my number

hmm I should probably reconvert the JDM kg/mm figures using my number..

Just updated the progress technology spring info... no hard numbers but said they provide around a 20% stiffer spring rate. They also said that the ride should be better than stock. Linear rate for the front, progressive rate in the rear.
They also said they would provide a money back guarentee if the ride quality was unsatisfactory, something I found quite interesting.

H&R was not as helpful over the phone... but I'll see what they say over email.

sweet! Can we sticky this?

progress tech are $169.95-5% (coupon: ptscionlife) at ptuning.com

i'm not affiliated, just shopping and thought i'd share!

actually gf springs have been out for awhile , the sportiest of the three. and old df210's where the purpleish lilac color , the newer df210's are white.

I talked to Eibach and the MSRP of the Sportlines is $319.00. But I have found places that carry them charge between $223.00 and $240.00

The HKS SF5 and the Tanabe GF210 are simply not listed on their respective websites for some reason. When/if official information for the specs comes out i'll post them up.

thanks for MSRP of the sportlines mooney. You wouldn't happen to know the pro-kit msrp too would you?

looking at Jeff's picture of the Progress sway bar (in another thread).... here is a crop of that picture

http://img398.imageshack.us/img398/6194/screenshot3139qn.jpg (http://imageshack.us)

and the reason for bringing this up here is to show that spring rates between rear coilovers V. plain springs are not directly comparable because.... the coilover type of spring has greater mechanical advantage than the stock type of spring.

what would this factor be? I'd need to measure.. but am not equipped to do that.

point: if stock xB/xA rear spring rate is x kg.per mm. .... and a coilover system were to have even that same rate, in effect that coilover is a considerably stronger spring. Yes? I think so. And, too, even if it were a so-called linear spring, in practice it will not have the linearity of a similar stock spring because it is being compressed -more- than does a stock spring. And so, it's rate effectively increases with compression because no spring, after all, is truly linear in regards to strain-per-mm.

just thinking.. correct me if I'm off base, thanks

I'm sure somewhere this makes sense, justnot in my mind at 6AM

Forgive my automotive ignorance, but I read in another post that a lower spring rate meant a smoother ride. So would I be correct in saying that buying the Tein S-Techs wouldn't help smoothen out my ride? Thanks.

The Sprint Performance Springs that you do not have that much information on.....
They suck....don't buy them. I paid $276 for mine and it's not a comfortable ride...

Agreed. I just installed some Tanabe DF210 springs (ordered from Havok) and they are white. I can tell you that the springs I put on are definatly the DF (dress form) series and not the NF210 since I got at least a 2 inch drop.

http://www.biblicone.com/photos/images/DCP_6987.jpg

I have to ask:

I installed the :Megan Racing which drop the Fr 2.0" the Rear 1.75" But what does these spring/rate mean Front = 280 Rear= 230 for a xB over the stock springs.

This is an excerpt of an email reply from Tanabe-usa.

"We do not offer GF210 for the Scion xB, that online vendor may have bad data. We only offer NF210 and DF210 for the Scion xB. The amount the vehicle is lowered is dependent on the way the vehicle’s weight distribution is set up from the factory. The spring rates and lowering data on our springs is set so that the car has a more neutral balance, and also sits evenly for a more visually pleasing look.

If you have any additional questions, please feel free to contact us anytime!

The website I found GF210's, as well as Tanabe's other springs and a bunch of other parts at some great prices. The site is www.suprastore.com. (I have no affiliation with them.)

I am with tazman. Now I'm a 2 on a 1-5 scale for being mechanically inclined, but what does spring/rate mean :question:

I have to ask:

The spring rate tells you the amount of force a spring exerts when compressed.

without getting too technical, the higher the spring rate, the stiffer the spring. Generally the stiffer the spring, the better the handling (less body roll), but also the harsher the ride (will transmit more road vibrations).

However, the spring rate doesn't always give you the whole picture of how a spring will feel, but it should give you a rough idea.

the figures I've given are measured in lb/in. In metric countries (i.e. everywhere else but here) they use kg/mm. A spring rate of 280 lbs/in (or lbf/in) means that 280 lbs of force is exerted by the spring for every inch it is compressed. Usually springs are linear, which means the rate never changes.

However some springs are progressive or "variable rate" springs. The idea is that they start with a softer rate (thus.. they absorb road imperfections more easily) and become rapidly stiffer as they compress (to perhaps assist in cornering). However, well this might be fine in theory, it doesn't mean that it works quite that well in practice (the progressive vs linear is much like the CAI vs short ram debate). It is very difficult to know what kind of ride you will be getting from progressively rated springs. IMO, its pretty much a hit or miss. In theory, if well designed, you can get the best of both worlds (the exact combination of ride comfort and handling you desire), but you can also end up with something you hate.

Cool, thanks. Now I know a rough estimate on what I want to look for if I ever get a kitchen pass to buy springs, LOL :pray:

I just install my TRD springs on my Xb and I got a 1.5 drop and not 1inch. If you do the math actually it is more than one inch when you convert from (mm) to inches. FYI

I just install my TRD springs on my Xb and I got a 1.5 drop and not 1inch. If you do the math actually it is more than one inch when you convert from (mm) to inches. FYI

where did you get the numbers for the TRD springs? I had some difficulty finding the exact specs

Hello,
So is it safe to assume that the Megen springs with rates of ~280/~230...have the stiffest ride quality?

I have these installed on my xB and they do transmit alot of road noise and I do feel the roads imperfections alot more. I however did not know this when I bought them...I just thought I would try out a different company for a change.

I'm glad I did, I absolutely love the way the car acts now. The front has finally settled evenly...been about 2.5-3 weeks now.

Overall I am happy to hear that the springs have a higher spring rate, complete surprise to me, but a good one. Thanks for the info!

-Brian!

Any one rolling on the Tenzos? Any reviews? None showed in parts section, so thought I'd try this thread.

i am about to get some Arospeed 17" Kino's for my xb. I was going to get Eibach Sportline's to drop it to inches but now i'm looking into getting the TRD springs and struts so that i don't void my warranty. How much fender to wheel gap will i have if i go with the 17's and the TRD springs and struts? I'm also going with I believe 215/45/R17 tires.

I just installed the TRD springs and It looks considerably lower, they havent settled yet, so I would have to get back to ya later about how much fender to wheel gap there is. Basically your fender will be aprox. 1 1/4 inches closer to the ground. I have 15x6 wheels, getting the 17's soon..

cheapest place to get tanabe's? the 2.2 drop ones

I have a question, as I am confused on something. I am looking to drop my Xb, but I want a nice ride. I want the ride to be smooth, and not bounce up and down every time I hit a piece of sand on the road(like the rice rockets usually do).

So, that leaves the question of what should I get? I like how the Stechs drop the car approx 2 inches. Will this give me the ride I am looking for, or should I be looking at a different brand?

what are good spring to have with fallen rims 18"

whats the closest to stock in terms of ride?

^ anybody?

Anyone know if TEIN has released an EDFC Compatible spring for the scion xA? Also are there any shocks that are as hard as the megan racing springs but don't come with such a large drop? Thanks

I want to install lowering springs hoping that would improve handling and reduce wind sheer. I am not looking for improving the looks or styling. From the list TRD and H&R look like good options. Please suggest.

Thanks,
Vinnie

Great thread but there are mistakes here that could cost people cash.

Just to help you update the Tenzo-R should be moved from Slight Drop (~1") to Moderate Drop or Low Drop since the specs are Front 1.6" Rear 2".

Can anyone tell me what the Tenzo spring rate is. I don't understand what progressive means. thanks.

Can anyone tell me what the Tenzo spring rate is. I don't understand what progressive means. thanks.

Not sure but I think it means it will lower a bit more over time. It will set in? At least my shop told me they would so I assume this is the case. Can anyone clarify??

What does "Variable Rate Spring" mean? Also what does the spring rate mean. if it is what is the difference between high numbered spring rate and lower numbered spring rate.

Heh, these are really good questions I would never ask here. Good for you. Anyone know? I don't.

Anybody heard of the JDM lowering springs on scion superstore? Here is a link...

What does "Variable Rate Spring" mean? Also what does the spring rate mean. if it is what is the difference between high numbered spring rate and lower numbered spring rate.

Variable or progressive rate means that the spring has different ratings as the spring compresses. The spring will have a softer section to provide a good soft ride and a stiffer section to slow the compression down when you go over big bumps to keep from bottoming out to hard.

Thanks,
VinnieSprings alone will not help much with handling other than lower the center of gravity. To improve the handling you will need a rear stabilizer bar (Progress, TRD or Whiteline) to name 3 that I know of for our cars. Upgrades shocks that are adjustable and to upgrade the front sway bar end link bushings to polyurethane to reduce flex. Hope this helps and enjoy your new corner carver!

Will the Tein Basic Coilover for a xA, fit a xB??

Yes they interchange

That's awesome Thank you. anybody else? so that I am super positive before i buy a set.

Thanks

Anybody have or know somebody that has the skunk 2 springs. they give a 2" drop just wanted to know the how comfortable the ride is.

Anybody have or know somebody that has the skunk 2 springs. they give a 2" drop just wanted to know the how comfortable the ride is.Springs carry the weight and have little to do with ride quality. If you plan on using the stock shocks the ride should stay the same as the stock springs. If you add the Monroe 5987 rear shocks, this will make the ride much less harsh. Hope this helps.

I've been riding on progress technology sport springs on my xb for over a year now .I have no problem with them except the ride is kinda hard when i hit a bump it feels like the back end of the car is going to fall off. A friend said chages the springs to tein. so i made a few calls and it turns out it not the springs at all its the dam low profile tires im riding on ,theres harly no meat on the tires so every bump feels like a dead body was thrown in front of me.

My point....

If you are going to change to lowering spring with low proflie tires with a half inch of rubber on the rim, your ride quality will suck .

Thank you every body for the info on springs :bow:

I've been riding on progress technology sport springs on my xb for over a year now .I have no problem with them except the ride is kinda hard when i hit a bump it feels like the back end of the car is going to fall off. :Actually, Monroe #5987 shocks would help out in the rear with that hard a$$ed ride. It is about a 70 dollar mod. The stock shocks do not compress during a bump so all that energy gets transferred right to the seat of your pants. :lalala:

word. i've been trying to research a suspension setup for my box for a month or so. i would like to do it before i go back to school. with that said, seeing as how i do go to school and carry lots of cargo, carry people, etc ... i was thinking of the following additions: progress rsb, energy bushings, rear monroes, and lowering springs.
however, i've been stuck on which springs to get. i am concerned with ride height and comfort. i definitely want something that is comfortable for my passengers (ie - ladies) and something that will not make me bottom out or even scrape everytime my car is loaded with luggage or a cabin of 6 passengers.
i've been debating between tein Htechs, Skunk2, and vogtlands. and i'm still not sure if those rear monroes will lower the rear even more ?
any input ?

This thread has great information about different springs. The problem is, being a buyers guide, providing information about the springs is only half of the battle.

A person looking for springs needs to find all obtainable information to make an informed decision on what to purchase. This information is found here without a doubt.

The second and last step is to find the best PRICE for the product. I believe that this is lacking right now but we can change this. Sharing information like this is a great way to make this forum more potent and helpful. It also keeps good businesses in well standing. Unrelated to suspension, I highly recommend vulcantire.com for any tire needs you may have. I found them to have the best prices on pirelli tires and their shipping was amazing. I have no relation to them outside of my purchases, but their helpfulness and services are the best I've found.

So where do you find a great price for the Tanabe DF210? NF210? Goldline Springs? Eibach? etc.?

Lets make this forum Grow!

^^^ to answer your question on pricing, it's really hard to say.
prices fluctuate so much between sellers and depending on the time of year. i personally would just say go to the sponsored sales section and just look around for the items you're looking for, PM the seller/company about their prices, and then price match as best you can to get a great deal.
also, froogle is your friend. froogle the springs you want and see what it spits back at you.
also, used springs from people on this forum is another great way to save. look out for people going back to stock or switching setups. you can usually get a great price on springs you're looking for that way.

i got my tanabe df-210's from chris at explicit-motoring. 909-319-7892. i believe they were $160.00 including shipping. mine are red in color. i replaced the TRD's i had put on at 1,500 miles and the ride is better and the look is the best!

THIS JUST IN!!! edited 11/28/07. to be honest guys, i only put the tanabe's on the front. with the TRD's still on the rear it has a very nice rake to it. and this is why you will see me in the classifieds selling TRD fronts and tanabe rears! also, the TRD's are stiffer and with the added progress anti-sway (rear) this bad boy goes EXACTLY where it is pointed at almost any speed!

does anyone have any good specs on the k2 motor springs

OK I am tired of having such a rough ride. Does anybody know what I should switch to for a smoother & more comfortable ride. I do not plan on lowering, but I did install the Hotchkis sway bars F&R, thanks to the DFW Scikotics, to get rid of the rocking when a strong wind blows or get passed by semi. It has worked great & has done what I wanted. Now I what to smooth the ride out. I just do not know where I should turn next.

You need Monroe shock and struts all around. Monroe now has part numbers for the xB front and rear. I have Monroes in the rear and they really smooth out the ride.

Cool thanks

No problem. The stock shocks IMO are way too stiff for such a lightweight vehicle. They do not allow the suspension to absorb the inpacts.

Question: I've just been on the tech line at Monroe Shocks and the rep said he had no record of a #5987 shock. They suggest a 5601. Please advise and thanks in advance.

hey tikithed....how and why are you getting passed by semi's anyway?

gonegray, 5987 was an Echo part number. For your xB go ahead and get the number for the xB. Let us know how they ride.

So I opted for the Eibach sportline springs and i have a nice smooth ride not as rough a ride as the Tanabe but the same drop. I have about 10k on the springs and i am sitting at about 2.25" drop front and rear while still on the stock shock front and rear

Wow i see this thread has been dead 4 long time, any1 running tanabes on the xA?

anyone has any picture with the s-tech drop

anyone has any picture with the s-tech dropYour best bet is to go thru the registry and find xAs that are running them.

IMO, the xA needs a bigger drop (like the DF210) to clean up the fender gap.

IMO, the xA needs a bigger drop (like the DF210) to clean up the fender gap.Agreed, they look like mini crossover vehicles at stock height. Hella fender gap to overcome.

I hope someone notices this. I am waiting for my new wheels for my Xa coming next week. 17x7 +40 offset, with 215/45 tires. Does anybody know how low i can go on springs without rubbing? Any pictures? Struggled looking from the posted photos.

For pics go thru the xA registry and see what others have already done.

Thanks! Found it!

anyone got the eibach sportlines? i recently got them and i don't know what the clear rubber thing is that is on the front pair of springs. it makes the spring oily and greasy. what do i do with them?

I just installed Road Magnet's 1.5" lowering springs, their linear rates are 175 lb/in front and 220 lb/in rear. They are currently $125 as long as you like "Bright Blue". You can choose from dozens of other powder coated colors for $30 extra.
