Very interesting, you may be able to get a full refund then.

It really just suprises me. I mean I could understand my Sprint springs being off since they are a lower end company, but come one, MAZDASPEED. ( I wonder who makes them for Mazdaspeed )

what gets me is did I just get a bogus set, or are ALL MAZDASPEEDs this way? (which makes me wonder how in the world they got those number???)

I think I read on here Eibach makes the MS springs.

Like Cam said Eibach makes them. I would definitely return them and ask for a new set, then test those. If you get the same results please post the results. Now that I think about it I don't see anywhere were MS says what rates the springs are, I looked everywhere. So even if they are off there is no way to get a refund due to false advertising.

.... I wonder where the hell I got thos numbers that are on the first post??? I have always heard about how the Mazdaspeeds are supposed to be real stiff, and the numbers on the first post show that. But again, I wonder where I got those figures.


Thats funny Eibach makes them. Eibach is here in California. but the springs had to come from Japan. (I was waiting a month for them to come in on the ship). so does that mean Eibach shipped them to Mazda in Japan, just so Mazda can then ship them back to the U.S. to Mazdaspeed Motorsports Development, so they can ship them to me?

betcha I got those numbers from here https://www.rx8club.com/series-i-wheels-tires-brakes-suspension-55/spring-rates-other-basic-suspension-info-79096/

Probably, that's were I first saw it I think. You may want to ask where he got his #'s.

what were your ratings on the stock springs Speed?....Guess we're not installing MS springs on your car this weekend then, huh? WTF is right. I wonder what my spring rates are on my MSset.

Kwescott.... read post 97. :)

and NO.... no installing them this weeked..... or ever. :/

Certainly news to me! I took the numbers on the MS springs off of the forum a long time ago, and had no reason to think them inaccurate. As the post says: "All numbers taken either from the manufacturer, or from other posts on this forum. Some we can verify, and a few we can't". The MS springs are one of the ones we didn't/couldn't verify, and it sounds like perhaps we should have? I do wonder where those numbers came from in the first place, since it's looking like they're not even close.

I'll update my post accordingly, and I apologize if anyone took our numbers as the gospel. I'll also put a notation on the other spring rates that we have on there that I cannot verify with the manufacturer. Nice catch speeddemon; do see if you can get a second set to verify your numbers too. I can't see them making one 'bad' set that is THAT far off, but stranger things have happened.

Also, is it confirmed that Eibach makes them? For some reason I was thinking it specifically wasn't Eibach, but I have no factual information to back that up at the moment. I'll see what I can find out.

DPE

Well it sucks to know, but I'm still happy with them. Car still feels great. I do wonder were that # came from.

IT's not your fault DPE (Phil).
This is why manafactures should give the rates. as you said they do not tell you what the rates are... they just say "stiffer". (which the rears are SOFTER)

I Think I might just have to go with the Tein S Techs from you. ;) (if I dont stick with my Sprints)

DPE, I just added your info to the first post. :) (Prices)

I just got off the phone with Mazdaspeed, they iwll return the springs, but there is one concern. I wrothe the spring rate on the inside lid of the box (like an idiot) and I should have wrote them down on a seperate paper. he said if they deem the parts unsalable they will simply throw the parts away and I will loose the springs and no refund. they will not even ship them back to me.

so I either risk loosing everything to try to get my money back. or I try to sell them.

I think I will try to sell them first....



SO who wants a set of Mazdaspeed springs???? :D: great lowering springs with a factory like ride. :) $215 shipped

brown sharpie!!!!!!

beers :beer:

he he... true!

and of course it with a black sharpie. only thing worse would have been to do it on the outside of the box. :/

yeah.. ive had my suspicions when i noticed how much softer keiths car was compared to mine. but since all i did was push down on the front and rear of the car, i figuered that it wasnt the best way of testing spring rates and didnt say anything.

i guess it doesnt really matter though. ive noticed that keiths car handles EXTREMELY well reguardless of spring rates. its more neutral, predictable and progressive then my stiffer and lower voughtland settup. also, didnt jason really like keiths car as well? if spring rates between MS and stock are almost the same, there shouldnt be that big of a difference between KONI + stock springs and MS sturts and springs. also arent keiths MS sways almost same as stock (15% stiffer)? the only other difference is that the MS drops the car about an inch. that shouldnt do much though. interesting...

...except now you have more front camber available...that with better shock may just made up all the difference.

^^^, yeah, more Camber available (which he is not using) and a lower center of gravity. but really it does not lower the car all THAT much. but I guess every little bit helps.

Supprising the rears are softer then the factory ones though. at least the front is a little stiffer. They make for good Drage race springs. :D:

isn't it interesting to take the new info that you have about your MS springs...when you compare them to the info we have listed for the Eibach springs.

Eibach Pro
Front drop 1.2"
Front rate 180 lb Progressive
Rear Drop 1.2"
Rear rate 130 lb Progressive
$230

or

MS made by Eibach....Would be interesting to put a picture of a MS and Eibach spring side by side. Eibach is progressive, but has a similar spring rate.

Then again, the MS cold air intake is made by AEM.

I'm very dissapointed if this turns out to be true...I will be much happier to know that you just got a bad batch. But then again, this may make me take the springs off my car to see what spring rates I have.......

so are we saying that my butt dyno...and spring stiffness thermometer are broken. Damn....and to think, I thought I had an accurate stiffness feeler.

+ 1 for Placebo Effect

yeah but the MS springs were softer then that in the rear.... I was pulling 100 pounds at most. :(

the MS springs are progressive also. (just an FYI) which needs to be updated on the first post.

he he... thats funny. when I was talking to Michelle last night about them she asked why people say they are so much stiffer. I said the same thing. Its the Placebo effect. you think they are stiffer, you make yourself feel the car stiffer. you think the intake adds power, you make yourself feel the car faster.

This is why Dyno's are AWSOME... they dont lie. (engine dyno, spring dyno, shock dyno.... ect.) (of course with that said, nothing beats real world and track testing)

I think this info would shock the RX8 community. I say you post a separate thread with this info....or, wait until you get the second set and then, based upon the results from testing that set...post up a thread.

People, maybe because of threads like this, are under the impression that MS springs are one fo the stiffest options....but this new information would drastically change my decision if I was trying to decide on a set now.

keep in mind Mazda did not say that the springs were so stiff. those numbers came from this web site. we really cant blame Mazda for our mistake....

Dissapointing yes, but cant take that out on Mazda.

(though I still wonder why bother?... I guess for the drop, and the little bit stiffer fronts.)

Hey guys, I was planning on getting the Tanabe NF springs coming up, but i remember reading some where that if you just get springs and not shock and everything else it can really mess up ur car. I was just wondering if this is true, or will I be fine with just the springs.

youll be fine.

OK thanks man

your struts may wear out faster due to the change in spring rate and dropped spring...but there is no rule that you have to change your struts at the same time....just a recommendation.

ok got a little more information.

Kwescott and myself (Thanks Kwescott) took the Sprints out of my car (well 2 of them) just to test the rates. Same testing as the stock springs and the Mazdaspeed springs.

Here is what I got:

Front
165
180
195

Rear
95
100
100


Dont know if anyone cares... but there you have it. :D

are you still planning on changing them?

no I dea now.....

Leaning twords keeping them in since at least they look cool. the only spring right now I am considering is the Tein S tech. I just wish I knew someone that had them NOT instaleld so I could test them first.


I just wish I had the money to go coil overs...

Called Petit.... they do not know the spring rates of their custom order Eibachs. they also mentioned that they dont really deal with Eibach any more.

added this info to the first page. (along with the sprint info)

I'm starting to think that Springs (within our price range anyways) are just for looks (ride height). It looks like you have to have some good money to throw at suspension to truely get something in the range that we are looking for.

yes..... I WANT COILOVERS!!!!!!!!

I simply cant afford them though.... at least not without being stupid. :/

but yeah, they are all pretty much for looks. I mean minor ride differances. but for what I want I need coilovers considering I am wanting to double the spring rate.... or more.

my fiend wants to sell me a new set of megans for under $900 total. they are 12kg/672lb front and 10kg/560lb rear (you can get 10/8 but its extra $$). the shocks are made by apexi and are monotube 32 way adjustable. the rears still have to be taken off to be adjusted from what i could tell but there are extender cables that you can get from megan that allows you to adjust them from your trunk. the fronts use pollowball mounts but ive driven a car with these and i couldnt tell the difference. they felt good though. much better dampening then the tein basics.

however, they didnt feel that much better then my voughtland/ koni combo. better yes, but not good enough for me to make the switch. i dont really need height adjustability (suposedly 2 way adjustable but not really... the top adjuster is for preload). the quality seemed decent. the springs had some scratched but that was about it. i dont like how the rear shocks bolt up to the car but its more solid then i give them credit for.

if you want them, ill tell him to give you the set instead of me. i gotta leave my car as is until after the academy.

i fnd this on their web site:

Megan Racing Coil-Over Dampers are the ultimate upgrade to your track or street car. Featuring 32 Levels of damper force adjustment, full-height adjustment, these damper kits are then perfectly matched with front and rear Pillow Ball upper mounts for camber correction in most applications.

The adjustment of the damper is as simple as can be with a built-in knob at the top of the damper mount for easy access. Simple adjustments can be made to tune to your style of driving and comfort level desired. Single-Adjustable dampers make suspension adjustments easy to tune whether you’re a professional mechanic or an automotive enthusiast with amateur mechanical skills.

The height adjustment is made easy with CNC-Machined locking perches for accuracy and smooth adjustment. You can raise your car up to factory height for OEM appearance with performance handling or you can drop your car all the way down for a formal racetrack and an aggressive stance lowering your center of gravity to gain full potential of your car’s handling capabilities.

On most applications, the Megan Racing Damper Kits come with fully adjustable Pillow-Ball upper mounts to easily tune and adjust your camber. Adjustable camber gives you an edge on most suspension setups, as you can easily tune your car for any ride height which improves handling, predictability and furthermore tire wear, which is a great benefit both on the racetrack and on the street.

The quality and durability of the Megan Racing Damper kits are unmatched. Made of extremely durable Steel and featuring springs that are constructed of SAE-9254 Cold-Wound Steel which are then tested over 500,000 times by compression inspection.

i guess $900 shipped isnt that great. i thought i was getting a better deal then that.

Guess there is room for making offers then. Casey, offer him 750 for the set and see if he takes them. You could probably make most of that back by selling the Sprints and Konis...if you end up liking them enough to keep them....or you could sell them on the RX8 site and just keep your Sprints/Konis. I'm sure you could unload them for 750.

i doubt he will sell for less then that. he suposedly gets them for 875 from megan. he was gonna sell me a set for only $20 profit.

ahhh, the way you described that they were scratched lead me to believe they were used.

speeddemon: I just got the Koni shocks and Sprint springs, I think you have a similar setup? Hopefully I'll get the drop you got. It's still half the price of a good coilover kit

chickenwafer...I hope you don't have the appearance package. That sprint drop is LOW.

I have that exact setup...... make sure you post me some pictures here!!! :)

no... unfortunatly, i was the one that picked them up from the warehouse. it may have happened during shipping. food for thought, my vougtlands had paint chipped off the springs when i got them as well.

yeah I have the AP.....I kwo it's low but Phoenix is pretty level for the most part. I was going to get the Veilside lip but I'll wait to see how low I go.

MM's car is SUPER low with the Tokico D-specs and AutoEXE springs- he tucks the rear tires, and runs the MS kit....I wonder if I'll be lower than him....

Speeddemon: I will post pics once they on in a week or so. I'm waiting for my GT Factory vertical door kit to be installed and then I'll take one giant photoshoot

Awsome. I look fowrard to seeing it. I am sure you will be lower. I have yet to see a sprint that is as low as the Sprints. (not talking about coil overs, or someone that cut their springs)

I love my sprints (well the way they look at least) I dont think I would want to go any lower though. I have a hard time getting in and out of places. I get stuck often. I sure as hell would not want any thing hanging off the front of the car as it would get destroyed.

also there comes a point when you get tooooo low. then it just looks like your on bags, or you just cut the springs to dump it. I think the sprints are the "perfect" drop. :) :) :) very agressive, but not stupid looking.

you made a good choice. :D:

yeah, if they're too low I might switch out to Tein S-Tech's or Swifts.....Still not sure. But I got a smoken deal on the Sprints so I'll stick with them. We'll see if I tuck my rear tires :)

dang it Casey, I wish I would have known about this sooner. I had a pair of S-Techs (actualy 2 full sets) sitting in my garage for about a month! :(

damn!! i want the sprints too!! hahah i am debating whether to go with sprints or espelirs. i love the sprints drop tho. SO SEXY. hahah right casey? hahah

thats right! :) :) :)

I will be taking the car in on Tuesday to get the alignment, so it look slike I will be sticking with the sprints. I figure they are pretty much the same rates as every other spring, and I love the drop... so Sprints it is for me. :)

Peter, you can always just get yourself a set of sprints new. they are not expensive springs. I think I paid $250 for them 2 1/2 years ago.


Jedi....... yeah, that would have been nice! :/
