I want to install springs on the car to get rid of the awkward gap mainly in the frontand for a lower better ride After researching springs, I've found that many forum members got Tein S-tech springs .

Does anyone know who stocks them locally price etc , what do you guys think.are they any good ?? other alternatives ?

cheers

As you know I put in King Springs and have nothing but praise for them. They are fantastic on the car, even out the gap in the wheel arches front and back, stop the car pitching front and back under acceleration & braking and most importantly the car still rides very well.

With them the car looks low but I do not have any problems with speed humps etc.

The best thing with them though is through Repco the trade price is approx $170.00 for both front & back... All 4. Very cheap upgrade indeed! As you were able to organise the sways at trade you should also be able to do the King Springs for yourself.

Cheers

i have k-mac springs, and know someone who has king springs.
another had the factory springs resetted to whatever height.
whiteline is currently doing 30mm lowered springs. i have stage 1 on my car atm, and 8A8Y 8 has stage 2. they are finalising the specs on the springs.

While King Springs are probably the best locally made springs, they do tend to sag a fair bit over time.

I've had them before on a couple of my previous rides and were fairly happy with the results, afterall, you get what you pay for.

If you only want to replace the springs and price is not (too) much an issue, I would recommend Eibachs or H&R Springs.

Tein have a great reputation when it comes to suspension, but I've never had first hand experience with their products, so I can't really comment on the S Techs.

Can you post a pic of your car so I can check out the height your 8 sits at. I've had King in the past and they're not a bad product.

Here you are. This is a picture auzoom posted of my car at our last Victorian meet. King Springs installed. :D :D

For a more expensive investment: coilover / suspension set

Tein is ok. HKS is actually better - you will be glad to hear it. But I like Fujita engineering - since it develop in the 8 for the 8 and tested in several circult in Japan while testing.

The only problem is to find someone to service it when it runs into problem. Tein and HKS then have people in Australia and SE Asia to do that cheap. If I go for Fujita Eng, then I have to send it to Japan to fix.

The king springs at trade price $170.00 for front and rear are hard to beat , maybe one day will go to the track and find out the difference in name brand aftermarket parts and good old no name Aussie ones :)

spring itself ain't = coilovers.

Spring is change to spring rate and height, the shock is still the same. I don't care how it is going to change it is still very minimal in real gain.

Coilover is at least 16 point adjustable. Japanese coilover are generally half price as the zeal, ohlins, bilstein, or other euro brands that goes into EVO8 MR and Porsches. They are much much better.

Very nice ILIV48. Definately looks better than stock. Repco here we come.....

adjustable spring platforms would be nice but how often would you change the settings? how many of the settings would you use? how easy is it to change them? do you really know what the adjustments do?
all that adjustability is only of use on race tracks for experianced user or with profesional guidance.

I reckon if you change the spring you should change the shock. motor journalists normally criticise the rx-8 for having a under damped rear end. I have felt it myself when you hit a bump mid corner the rear bounces and becomes unsettled. how do you fix this by going to a stiffer spring? you just make it worse.

The white line swaybars have done a lot to counteract the wheel hop you have mentioned .

They are 30 gradings of damper setting in the HKS Hypermax II.

Spring rate change, you will need to change to other springs. Some very nut track racers have one spring for street and one spring for track. And they usually adjust wheel alignments after each change.

How to change the damper setting? Front it is easier, it is just under the bonnet. The rear is a bit hard to gain access to. Therefore, some people have a EDFC - an electronic controller that you can change in your dash, with 3 preset settings that you can change in seconds. EDFC is only available to Tein.

Changing Spring rate and ride height without changing the damper rating.... hmm :rolleyes:

Which shock will be compatibe to the spring that you change to?

People are happy with MazdaSpeed spring with MazdaSpeed shock. At least they are developed together.

If King spring comes with King shock for the RX-8, then I will be interested of how it does...
It may be $170 to make it worse... well it will be defitely worse if the installer you choose have f up for camber and toe settings.

I do a lot of MTBing.. and in this world, because of the inefficiencies of the power plant (lower power output, low rpm, imbalanced etc etc) we have what they call "pedal platforms" on our shocks. Basically its a low speed dampening circuit. It also helps with brake dive.
Is this the same for the automotive industry?? do speed and position sensitive damper exist at an affordable level??

The white line swaybars have done a lot to counteract the wheel hop you have mentioned .

I don't really like your thinking Lock. Get your son to show you the GT4, Lock. Play with a car that have all spring, damper, ride height and stabiliser setting. You will start to learn what is right for you.

I have been know to get the car a slight understeer and my other friend abuse me for that... :)

Taka do you no the original set up numbers for our cars , i have just had my wheel aligment done and my cambers were adjusted so far it feels fine but i agree setting up your car is a very specific and sensitive task best left to experts .

L&L the wheel hop you are referring to is axel tramp a different situation.

I just talking about when you go over railway lines or something similar. the rear end will go up and down a few times before it settles down. if there was a stiffer shock on the std springs it would control the rebound more and the springs oscillation would subside quicker. if you have the std shock and a stiffer spring it will want to bounce more and continue oscillating.

you can see it on lowerd cars with stiff suspensions; they will be driving along a relatively smooth road with expansion gaps running across the road and you will notice them pitching back and forth like a bucking bronco. their shocks can't control the overly stiff springs.

Well so far I find my car handles mid corner bumps better since the Kings. The rear end feels more planted and to me it does settle better after a bump. It certainly does not bounce like it did when standard. For now I am very happy.

I do intend in the future to upgrade the shocks and springs to a full package. But wheels & semi slicks, some dba rotors, brake pads, racing beat intake & RP high flow cat are all first on my list. Then if I am still completly fixated on track days I will do the full suspension package!

Damn I know how to spend money. And thats even before paying to be blown by Hymee!

so does anyone have some local prices for these things?
i found one where Tein is $400, Fujita $599.

I'd give mazdaparts.com or one of the american sites a go. the exchange rate is good at the moment and you may get better prices than those quoted in .jp. the postage is high but not ridiculous from the quote I got from mazdaparts.com.

They had to be spring only but yes about that much.

Jarl,
US$ 77 cents. 1AUD = 82 Yen :eek:

Both US and Yen are weak. Hurray AUD! :D

ILIV48

Your king springs are they the standard type or the lowered type ??
Any news about the DBA ROTORS AND PADS .
