AND on top of what spin9k said these will RIDE better then any coilover on the market, due to its:
1) Lower spring rates then most if not all Japanese coilovers on the market
2) Precise Valving to match the rates
3) The Progressive Rear Spring

Its a WIN WIN for whatever floats your boat!

MAN ! how the )#@!*$#@$ do I miss this ?

if I can spot this GB couple days earlier I could've jump into this GB .... now I just spent almost 1 K on my flywheel + clutch setup ......

I want coilover but what is the HIGHEST height settings for KW Var 3 ? I want to try some track this year, but before that this is still my daily driver, and New York City has the shittest road ever, so I need to know how high can this go before I check with my bank ...

What i was told by KW is that the "lowering adjustment range" was from .08-2.0 in the front and .06-1.8 in the rear; these are also "TUV" approved as going lower or higher would cause undo stress on the spring or at least I would assume.

I'll ask if you can go higher then OEM, but it probably wouldn't be advised.

Btw you've never seen New Orleans roads, i've driven both and let me tell you i would pay you for the ground your on right now.

According to my calculations they are exactly the same as most 8 kg/mm front and 5 kg/mm rear (445/55.88 = 8.14 & 255/55.88 = 5.1). Same as Cusco & JIC. HKS is 7/5, Zeal Xs is 8/6.

That being said these are WAY better. Dual adjustments, stainless, warranty... I'm so tempted but I just got my 8 and have a big list of to-do's! I don't need further selling, just need to make up my mind.

According to dpeweb.com:

JIC "hard" is 560 front 392 rear "soft"'s are almost the same rates.
I'll take your word on the other ones tho.

Hmm, well I got 2 bent OEM wheels , and 3 sidewall cuts Proxes 4 .....

They dont have to be as high as OEMs, an inch lower should be *fine* .... but nothing lower.

I've got 2 bent OEMs, but you have 1 more sidewall then me so touche. Then i did all that inside 3000 miles

Then at .08 min and .06 min in F/R you should be "okay"

The ride height doesn't really effect the damage from potholes, unless the car bottoms out.

I suppose you loose a bit of suspension travel...but it's the springrate and damping that depends on the "hit"

The difference between OEM and coilover doesn't make much difference when you hit a big hole

I know

Thats probably why my gf said I drive like an idiot now, cuz I keep on dodging all the holes that I see, deep or not.

Aye ...

I did all that in 1/2 year.

Now I think I need to check my bank account and see if I can *use* that much money in a month ...

These explain the general principles, however after I recieve my set I'll be posting a detailed DIY on how to get the "best performance" from these, if you feel thats too hard for daily driving you can soften compression(they call it bump in this pdf) and rebound from the "best performance" setting until your ride is comfortable.

BTW i don't expect the performance settings i'm going to run to be that uncomfortable on the street, so i'm not woried

Basically guys its not that hard your turning 2 *****... not one... don't worry about it !

That might be a little risky, i'd perfer to ship them to you in the Far East, I believe KW is drop shipping these straight from Germany so the shipping charge won't be much greater to ship it from Germany to Asia.

Talked to KW again today, if you track your car frequently or auto-x and would like custom spring rates its +$125 and once again you'll loose the lifetime warranty, original post updated.

Saw myself quoted, and just wanted to clarify. The standard JIC FLT-A2s are 448lb front and 280lb rear springs; very close to these KWs. Not speaking to the quality of either, just saying the rates are very close. And they use progressive rear springs, just like the KWs.

Note that spring rates don't necessarily equate to ride harshness either. All else being equal (such as getting stiffer springs for these KWs as is an option apparently), yes, stiffer springs = stiffer ride. But as we all know, all else is rarely equal. There may be a substantial difference in ride between any of the common coilovers out there despite having similar spring rates.

Looks like a hell of a price on these, by the way, and on paper they do appear to be the best thing going. I'll be interested to hear reports from the track to see how they do compare to the other options out there.

Just curious, do they use the OEM upper mount in the rear like JIC and HKS, or do they have their own pillowball or rubber-isolated mount like Tein?

I've heard Yes from someone and No from KW-USA, I'm asking Razz to clarify this for me?

For those that don't know what pillowball mounts are, you probably don't need/want them. They basically transmit much more precisely movement to the coil over, and allow for camber alignment adjustments to be made more easily/precisely on strut type suspensions. HOWEVER, these are usually for diehards as they transmit much more noise and vibration and in some cases need to be replaced annually or bi-annually. I don't even think I want/need them.

If its a No, KW-USA says they are developing and will have the upper pillowballs for these coilovers within 2-3 months, however if you absolutely want them now they sell pillowballs for their fullout racing suspensions, however they are a little pricey $300-350. The ones they are making for the Variant 3 will be $200.

I only ask because if they do use the OEM rear tophat and do not come with a cable, you will not be able to adjust rebound in back with them on the car. Now if you come up with some cables, as I think we've discussed in the past and you mention in this thread, that would take care of it.

If they come with their own upper mount, you MAY be able to adjust the rebound in the rear fairly easily by pulling back the trunk liner. This is true of the Flex and MonoFlex, which use their own rubber isolated upper mounts. HKS and JIC come with extention cables to take care of adjustment using the OEM upper mount, as do Tokico D-spec shocks (if you buy them from us ).

Just something I'd like to know personally, really. I wouldn't mind trying these myself. Where is Razz? He has about 4.7 million posts, so I know he spends a lot of time on here ......

And on a side note, pillowball or otherwise custom upper mounts do not effect/control camber or caster on the RX-8. That is only for cars with strut suspensions, in which case it is usually very desirable to have them for the alignment adjustability. In this case, pillowball upper mounts will simplify the install a bit and allow for a bit more precision in how the dampers respond, and may ease rear rebound adjustment if they do in fact make rear mounts for it.

In either case the cables I'll be making are a must because that whole processes of pulling back the trunk liner is just too big of a pain in the *** and somewhat difficult from what i hear.

Hell if they only cost me a few buck a piece i'll make them free to the members of this group buy

EXCELLENT NEWS; We no longer have to do a 10 person miniumum order I will be doing the group buy in sets of 2, best thing is the price is still the same, so if you have signed up, pay up, and things will drop ship straight to your door.

1. Dannobre - Awaiting Payment
2. MazdaspeedFeras- Awaiting Payment
3.
4.
5.
6.
7.
8.
9.
10.

For the inital order I would like to have at least 3 if not 4 so noone at KW has any doubts about if this was a profitable idea or not, so lets get 1 or 2 more guys

Payment info has been Edited as i didn't realize that paypal fees would be $50 if you paid me via it:
"Payment, I would perfer and its in your best interest to pay with cashiers checks or money orders to avoid PayPal fees, if you do pay with PayPal I have to add on a $49.89 to cover the 2.9%+30 cent fee. Paypal email is Mark87g@comcast.net , shipping address for cashier check or money or is located here:

Phil (DPE) could I pursuade you to send me a set of those cables, it might be to your benefit as they may be compatible with the KW adjuster and a cheaper alternative then me having to pay for the materials to fabricate them for the members of the group buy?
I won't damage them in anyway and if you want i'll pay for em long as you promise to return them if they aren't what i'm looking for, or if i look at them and realize that I can do what i need to for $50 bucks at home depot for 10 people.
