how much do you think they will be? i REALLY want them, but if they are too pricey, i guess i'll just stick to the cheaper ones.

check the front page of this thread.... :)

I think they are one of the cheapest springs you can buy....

really?? front page states 228 right?? i found some site called importdoctor and it is selling them for about $190. haha damn!! iono what i should do... still debaitn.g..

peter: you keeping stock struts?

naw, i am getting the tokico d-specs wit the cables:). hahah coilovers are too expensive:(. (I'm short on money because im getting the feed final drive:). yay!!!)

^^^ Lucky....

Mazdaspeed Springs
 

I spoke with Mazda Motorsports Competition and asked about spring rates. They didn't know but thought the springs were about 20% stiffer than stock. However, the interesting thing is that the spring rates for the springs and the Mazdaspeed coilovers are completely different. The coilovers are upto 90% stiffer so a 280 lb spring rate seems reasonable for the coilover. It looks like people just assumed that the spring rates for the springs would be the same as for the coilovers and that is what has caused the confusion.

Well, my nearly worthless information for the day comes from my local dealer parts department (whom I like and are generally informative, actually), who contacted Mazdaspeed about the springs. The answer he got back on the rates was "49 and 34", in some unintelligible unit of measure. Now, this is a stretch, but if you did 4.9kg/mm and 3.4kg/mm, you'd come out at 274lb/in and 190lb/in, which is very close to what has been said of these springs in the past (280/190).

As noted, this may be totally irrelevant info, but I'm going to prod them to find out more on the subject and see what they come up with. It may be that the 49 and 34 equate to roughly what speeddeamon measured on his spring tester in lb/in, in some strange unit of measure that I'm not familiar with. And if someone saw those numbers back in the day, they may have coverted them into kg/mm and ended up with the rates that have been taken as truth until now.

Anyway, we'll keep after it. And until then, we've got a whole bunch of Tein H-techs and S-techs in stock, just FYI :).

damn, no one has the Tanabe GF's yet....

I'm really considering them, but would like someone that has them to tell me how good they really are.

none of those OE type springs are stiff enough, you need coilovers to get decent rates

DPE... thanks for the info! keep us updated.

TeamRX8.... yeah this is true. I want to go with something MUCH MUCH stiffer. and none of the springs above are even remotly close. :(

Why cant someone just make a stiffer freakin spring. I mean come on, really now. do we really need all those springs that are vertually the same. :-/

I just need to start rolling pennys so I can afford the coil overs.

actually if you dont want body roll just get some stiff sways and a good spring

He has the Racing Beat bars along with Koni struts.....and in the quest for a "good spring"....it seems that most of the springs that we have looked at so far have similar spring rates...it is just ride height that differs (that and the actually measuring of spring rates rather than what the company advertises).

^^^ What he said.

speed: just get some S-Techs and call it a day. :D:

not untill I find someone that wants them "tested" first. I dont want to raise the car for now reason.

and honestly. even if the Teins are what they claim. I still dont think its enough to make it worth it. they are only a little stiffer then the sprints I have now.

...but then again, haven't most people suggested to you that your car is too low and that the driving issues you were having may be related to hitting the bump stops? Raising the car to Tein S-tech height may actually improve more from getting away from the bump stops.....

There's something you dont' see every day.

Yeah, the Teins are now selling a RX8 lift kit....:)

lol

I have the stiffest front bar made (1.25" OD x 0.25" wall) along with 575 lb/in (10.4 kg/mm) front springs and stiffest rear bar made (0.75" solid) with 325 lb/in rear springs (5.9 kg/mm) and still have a lot of front roll using street tires

race tires need some serious springs, Speedsource ran 800 lb/in using DOT-R tires, race slicks will need much higher ...

Yes Kwescott... thats why I need to check for the the next time we go out.


Crazy Team. :)

Kay i got a question... if i'm getting S-Techs then what shocks should i go with? How do you decide on what shocks will work best with what springs? I've always wondered this so if anyone could spell it out for me i would greatly appreciate it...

Thanks in advanced..

we're not professional racers....if we were, we would go through the time of customizing valving in the struts for a specific type of racing...

...the option that we do have is going with a strut that have adjustment capability. This would allow you to "fine" tune your suspension to your needs. Koni and Tokico are a couple of examples of struts that have adjustment capabilities (based on the strut model you select).

....there doesn't seem to be a "best" option, except if you stick with a lowering spring that advertises similar spring rates to stock.

^^ to add to that. most people seem to like the Konis better.

mehhh I was meerly saying "to reduce"... its damn near impossible to have 0 body roll unless your car is on the ground with no wheels :lol2:
