EOI: Tein Monoflex AUS-SPEC Coilovers

Simple

Smooth roads and smooth tracks, fast and high load require stronger springs like Phillip Island but even there spring rates too hard for rear wheel drive car. Bumpy roads and tracks like Australia mainly has requires much softer springs and valving.

Just check Jap cars they ware out on the inside and have very few stone chips to windscreen or front bar paint. UNLIKE Aussie cars that are on rough bumpy roads in comparison and get lots of stone chips.

 

Well now..............

................I have had direct feedback from Forum guys with zeds that have the Jap Spec Teins fitted and they are totally happy with the ride on the Australian Roads..............? And, they are more than happy with the lower price they paid per set They also have not been concerned with the Warranty issue because Tein is Tein, a great name, and a great reliable product.

 

No............

....I did not miss that at all, I think it is great that you are giving the market this option, particularly in a GB to make the product more affordable:zlove:. Tein is a great product whether it be Jap Spec, (which is also USA Spec), or so called Aus spec, and in fact nearly all of the coilovers on the market are great products. Chrispy summed it up best in his post above. Let the market decide, as long as they have all the CORRECT information

 

Rob/JP can you please explain the "re-valving" to me? I can understand the different springs which most coilover manufacturers offer for a little extra money. But the actual valving has me confused, Why change the valving on an adjustable shock? Seems superfluous to me...

Please enlighten me, as I've noted before the only think I can think of is the proportion between the rebound and compression or the total range of adjustment.

On the subject of coilovers anyone checked out the Hotbits coilovers? Aussie made and have helper springs and REALLY adjustable shocks. Might be worth a look, specially for a run of 10 or so.

I've been poking around lately at coilovers and if I didn't recently buy some slightly used ones I would be up for a GB. I may still if the product is right.

 

Rob....

..You seem to be the one who is in the ''match'' as you put it. Why not Keep it objective and accept the pat on the back. I think if you read things properly I have commended you on this GB. :zlove:

 

Well

Firstly the Jap USA Flex are not as overly hard as the Monoflex are for Aussie conditions.

Crispy re the revalving, adjustable shocks only adjust about 10 % of where they are set and most of these FLing DUng, WIng WOoo shinny copies from our experience and shock testing do stuff all. Even 36 way adjustment. This is why race cars often get adjustable shocks revalved to suit after trial and error and educated guesses. The other problem is there is a factor called engineering, quality, function and reliability, which Tein and some decent brands have. I won't mention brands but if not Tein, and other decent Jap brands or Bilstein and you should know what the copy ones are. Including quality internal components, correct valving and some thought into how it ramps on and rate etc. We have found up to 30% variation left to right even after adjustment on shock dyno on cheap Chinese or Taiwanese made coil over?s. Usually get what you pay for, although if cheap but does not last or do the job then expensive.

 

Also

I realise not cheap but not that much more than cheap poor quality ones. Although re the price show me where you can buy a MONOTUBE adjustable height and adjustable shock for anything like this price, without mentioning quality, as I don't think anyone does Monotube in these generic brands for zeds??
Monotube are more precise, far less fatigue from heat and more reliable and better for the track.

I believe.......

....that JIC make the Monotube dampers also

 

THE jAP SPECS in monotube are front 9kg and rear 7kg
what will the aussie spec be?

Also another question...if you have two 300zx's, one that weighs 1580kg and the other 1300kg with the same spring rates .....will the springs feel firmer on the lighter car ?

 

Thanks John, first person who has been able to give me a actual answer on the subject. Ever.

There are actually many monotube coilovers out on the market today for very reasonable money (less than $2k). I know I have a set in my Z now. Can't comment on the quality though...

 

Springs rates

BLACK BEAST yes lighter cars require lighter springs. There is also a factor called motion ratio which means the amount of travel the wheel moves compared to the strut. It depends on the angle and I remember the rear of a zed is about .8 to 1 and the front is less. If comparing a Z32 to Z32, no problem or confusion unless geometry has changed by customizing pivot points. But often a trap if comparing say a another car altogether like a Porsche or V8 Supercars etc. One car with 600 pound springs even same weight might effectively be the same as car with 500 pounds springs with a different motion ratio. Then is it 4wd or rwd, what is the weight of the car, and percentage front to rear, road or track car or both. If a track car though dose it have aero mods, as my car gets estimated 200kg plus rear down force from rear wing alone.

RE the spring rates nothing fixed yet and require more thought and discussion with Fulcrum suspension, who will do the custom valving and spring rates, but much less than 7kg in the rear that is for sure, and less in front also.


Here is a good link that explains motion ratio and more. There are some great links of this by clicking on the first link in the info headed, "vehicles suspension".

Not quite.....

....correct, Ksport have been making the monotube dampers for the Z32 for years, as have JIC:zlove:

 

You can put me down as keen to buy.
Unfortunately I cannot give any idea of timing yet. This will depend on exactly what is found when my motor is pulled down - in September/October. Therefore timing will either be Octoberish, or will drift into 2009.

If that excludes me from any GB benefits, so be it.
