TEIN Mono Flex - FD3S RX7

Mono Flex replaces TEIN's very popular Flex coilovers. Highly recommended for daily drivers that are regularly tracked.

But i don't see it on teins site:

http://www.tein.com/mfpdamp.html

 

It is on the Uk site, here you go.

good find. thanks.
RX-7 FD3S 91-02 MONO FLEX SA GSM32-F1SS1 £920.00 £1,081.00 €1,360.00 -30 -20

i wonder if it'll have the same spring rates in the US because its listed as 10/10. the current flex's are 10/8:

Kit Part No. : GSM32-F1SS1

Ride Height
Drop (mm) Spring Rate
kgf/(mm) Spring Rate
lbs/inch Ride Height Adjustable Range (mm) EDFC Upper Mount
Ft Rr
Ft Rr Ft Rr Ft Rr Min ⇔ Max Min ⇔ Max Part No. Note Ft Rr
-30 -20 10.0 10.0 560 560 0 ⇔ -110 0 ⇔ -35 EDK05-12120 ♣ P/U P/U

 

another european shop selling them:

i wonder if any us shops/sponsors will pick em up soon.

 

The US model ones will be different (different spring rates and damping), that's why they're not available here yet. They're not actually a replacement for the Flex, they're a replacement for the RA and maybe a couple others. They're a step up from the Flex.

 

thanks man. is there an ETA on when it'll be offered here?

 

I'd emailed them last year, and all they said was to check back again later.

 

As a FYI,

Cusco Zero2E, just got email that they do produce this for the FD and they do have the E-Con to control damping from within the car.

I'm gonna setup a GB on this coilover shortly to see if anyone wants to get in on it.

MSRP with normal mounts: $1760.00

Pillowball: $1960.00

E-Con: $360.00

Just waiting to get spring rates.

thanks, Rishie

 

Ok so spring rates are 10kg and 8kg for the FD.

Rishie

 

is that cusco a monotube or twin-tube?

 

What's the pound equivalent of 10/8?

 

10 = 558
8 = 447

 

Ya i just Multiply by 56 to get approximate.

 

for those who care...

i recommend Tein. i run Tein. i had a shock dyno and a digital spring rater so i know what's inside them valvingwise.. w 16 adj anything you want.

10/8 is the outer edge of an acceptable streetable spring rate. i run 8/6 but 10/8 works fine. 10/10 would be a disaster unless you like to burn up rear tires and slide slowly.

skip the "pillowball" option. it is just the opposite of what it appears. the "concreteballs" are solid upper mounts for the spring. solid as in major NVH. and there is NO performance improvement. the A arms scribe the geometry NOT the upper springmount. there is a reason Mazda put a rubber insulator between the spring and fender.

i love my Teins bought in 99. never beaten on the track and great on the street.

if you are on the fence on this i say go for it.

howard, why do the SM2 national champs use 950/750 springs?
just curious if your comments are geared towards street users who use street tires if they ever would venture onto an open track?

but what about autocrosser who use R compounds, like v710 or hoosiers? you still think 10/8 is good?

 

a reasonable question...

as i have generally stipulated, my suspension setup recommendations are for aggressive street and road course driving not autocross which requires instant turn-in at lowish speeds.

each of the various motorsports activities requires a different setup. i am only qualified to opine on road racing and street driving and will defer to others who have experience in other motorsports activities.

cool. thanks HC.

i got this email from tein about the mono flex:

 

What is the advantage of mono over twin tube? Weight I'm guessing?

 

mono and twin each have + and -.

mono gives you a larger piston that can be more sensitive to tuning.

mono does carry the risk that if the outside body is dented the shock could be scrap.

as to the post w the quote above.... about 10KG and they might be stiffer?????? why don't you skip running a spring and just bolt the corner solid? that's ridiculous unless you are drifting.

a 10 kg spring is about 560 pounds per inch.

that's the FIRST INCH.

the second inch is 1120.

the third inch is 1680

the corner weighs, say, 725. do the math and draw your own conclusions.

further, i really like driving my FD everywhere. it is a pleasure because i am not pounding my guts out and i run 8/6 or 432/378. if i switched to 10/8 my lap times would not improve.

stiffer cars do not transfer less lateral weight. just because your car isn't rolling in a corner doesn't mean you are going faster. dynamic weight transfer relates to center of gravity and track dimension. period.

stiffer cars break away from grip w less feedback making them much harder, if not impossible, to drive at the limit of traction. (drifting is not controlled traction BTW, it is controlled sliding)

when you consider coilovers, consider the SPRING RATE FIRST.

howard coleman

 

Anyone have a pic of the "regular" vs. "pillowball" upper mounts?

 

Scott,
You need some 750 front springs minimum and 650 minimum rear.

With your cars power and tire size anything less you'll be waiting for the car to turn in along with eating your fender liners (mostly on road course transitions from down to up). I'm currently running the Tein Race coilovers w/ approx 1k front and rear spring rates and love them. My car is close to stock ride height and I'm still rubbing here and there. I have also driven on about every frikken coilover setup made for these cars and I'm running similar or better lap times with these coilovers compared to some other cars I've driven with more power. When I was driving Brad Barbers old car the rates were 1k front 700 rear and the car pushed a bit too much for me causing me to LIFT which of course means you lose speed. Also don't lose your ABS because heavy springs are deadly under braking in the rain.

The Japanese race coilovers have equal VERY HIGH spring rates so you can slide it in FAST and get back into the gas. That said you will have to be good at catching the car but as you know that's what getting into a corner is all about.

 

^^^^^

Agreed, after seeing (and feeling) how Frit'z car handled with super high spring rates, I'm alot less afraid of them. 550/450 is very borderline.

The major slide-n'catch act I'll leave to Fritz for now though... I need a little pu**y-push!

 

Pete,
We all have different styles but as our seat time level increases the more we want the car to turn because as we keep getting faster with greater speed comes greater push. However in your case you don't need that pu...y push you just don't won't to scratch that little honey of yours.

It's all about turn in because the faster you're going the harder it is to get that baby to TURN IN

I think Scott's car has like 400 rwhp and he's running off set tires with 275 in the back so yes he'll need some TURN IN. With his power and torque you could just hit the gas then turn wheel and drive that baby straight up a football field hehe.

 

I just ordered some TEIN Comfort Spec coilovers for my FD. They come with a harder rubber not alu top mount, monotube design, the new valving and some softer springs. I'm eager to see how they perform.

 

got another email from tein:

Thank you for your interest in TEIN High Performance suspension products.

Actually, we have just finished testing the Mono Flex dampers for the FD3S
Rx7. Production of the coilovers has already started, and we expect to see
them within the next few months. Please keep posted with us for more
updates.

Should you have any further questions, please feel free to let us know.

Best regards,
Sales
