Hello all!
As we’ve mentioned in a few previous posts, 2014 has some new TEIN products in store. We’re revamping our Mono Flex line of coilovers with the improved Mono Sport line. We’re also adding to the successful line of EDFC Active controllers with the new EDFC Active Pro, which now has independent corner adjustments!
Please check out our YouTube page for new videos! But, for more convenience, check out the links below 🙂
That is correct!
If you have recently purchase the New EDFC Active and now have heard of the EDFC Active Pro and would like that model instead?
Well, good NEWS! You are able to make your EDFC Active to EDFC Active Pro.
What are the differences you may ask? Well check them out. Below you will find the EDFC Active/Pro Functions Chart.
You may be asking how am I able to get this done and how much will this cost?
Version upgrade service, to convert EDFC ACTIVE into EDFC ACTIVE PRO, is now available!
This service is only available for those who are currently using EDFC ACTIVE.
With this upgrade, EDFC ACTIVE can be turned into EDFC ACTIVE PRO, without purchasing the whole new controller kit.
Cost of EDFC ACTIVE Version Upgrade Service is $240
Customer must send their original EDFC Active Control Unit to TEIN USA, Inc. for the upgrade service.
ETA for EDFC Active to EDFC Active Pro Conversion is 3-4 weeks
For obtaining vehicle speed signal and using external inputs, Signal Converter (sold separately) is required.
Signal Converter (EDC01-Q0351) $110

As a suspension manufacturer, we’re proud to be able to offer both monotube and twin tube dampers to the market. Both of which offer their own merits in terms of performance.
It is typically viewed that monotube dampers offer the best in performance. They tend to have the most damper oil capacity which reduces damper fade. It also uses a much larger piston which allows us to tune compression and rebound better. It also separates the damper oil from the nitrogen gas charge, eliminating any chance of aeration (mixing of oil and gas, creating bubbles; decreasing damping effectiveness).
In short, monotube dampers sound like the best all-around choice when it comes to performance. However, one area it lacks in is structural rigidity. On strut suspensions, the damper is integral to the knuckle assembly. So that means that the damper must take lateral loads (side forces).
In the drawing above, you can see how this side loading affects the damper. 1) when the tire exhibits lateral loading (in this case, pushing the bottom of the tire towards the center of the car), its tendency is to push the top of the tire outward, away from the car. 2) shows how the wheel/tire assembly wants to rotate due to the added torque from lateral loading. Because of that lateral loading, this places stress on the damper assembly (3).
By our design, we typically make the piston shafts of monotube dampers small in diameter, so that the damper has the highest possible fluid capacity. We could make it much thicker, but then the damper body would probably be much longer since the thicker piston rod, when compressed into the damper, will displace a lot of damper oil (meaning that we’ll need a larger volume for nitrogen gas).
But, to reduce the amount of side load stress on a smaller diameter piston rod for monotube dampers on strut type suspensions, we invert the damper assembly. In doing this, the damper assembly (body containing the oil and gas) sit at the top, and we make the shellcase (strut body) the bottom portion. Essentially, this makes the strut look like it has a massive piston shaft. But, this visually larger diameter can hold up well to the stress of lateral loading. We’ve been able to perfect that design very well, especially in our Group N. rally program.
However, there is always a way to improve. Our new triple tube damper is the latest in strut type monotube technology. No longer do we need to invert the strut. Now, the monotube damper again sits inside the shellcase (lower portion of the damper assembly). However, in between the damper and shell case is another tube. This extra tube can be seen visually (actually looks the same as an inverted strut), and not only protects the damper assembly, but also increases the dampers’ ability to take the lateral loads without adding undue stress and friction under operation.
With this triple tube design, we can now add another guide in which we can distribute lateral loads without affecting the complete damper body’s strength and also reduce friction which can affect damping force.
I took a few pics of a Mono Sport strut damper that our R&D guys were working on
Here you can see the shellcase (black) against the damper (which is covered by the shiny outer tube).
To remove the shiny outer tube from the damper, we remove the insert top (this insert top is what mounts to our pillowball mount, which also holds the damper click knob or EDFC stepping motor). You then have access to the piston rod of the damper. 
The shiny outer tube has to be unscrewed from the bottom of the damper. Once removed, you have the complete monotube damper (our engineer reattached the insert top just as reference to show the top of the damper).
From there, it’s pretty much a standard fare monotube damper. However, the new Mono Sport coilovers have new features like Advanced Needle and Advance M.S.V. that separate it from the Mono Flex coilovers. The Advance Needle and Advance M.S.V. provide a broad range in damping force change over the 16 usable click settings, much more noticeable than its predecessor.
These new features stem from improvements we’ve made to our Gr. N dampers with F.R.S. A true testament in TEIN’s research and development in bringing racing technology to the street.
We’re definitely proud to bring the latest technology to the customer. We’re always looking to improve our product. After all, we are TEchnical INnovation!
Our Specialized Damper Program allows for a custom set of coilovers to be made to your specifications, but what about springs? Well springs can also be produced under this program. We have offered coilover systems which utilize a HAS spring for those with a suspension design with a shock spring separate from each other and spring rate changes for those are not available. A custom rate and length set can be produced to your specifications.
Even if the application has no product available for it, a custom set of lowering springs can be produced again to you specification. As this is a made to order set, time frames would be around 2 to 3 months for the manufacturing process as well as container freight from Japan. The starting price for a pair of reproduction springs can be anywhere from $350.00 to $450.00. A complete set of custom lowering springs will be around $700.00 to $800.00. Although the price may be a little steep, keep in mind that this would be your own custom one-off set of springs which no other consumer would have.
For further details of this program please feel free to contact us at 562-861-9161 or email tus_sales@tein.com and a friendly staff member will kindly assist you with your inquiry.
Okuyama/Carbing is one of TEIN’s larger product lines we distribute in the Japan and the U.S. They are well known for chassis bracing such as strut tower bars, lower arm bars, and frame braces.

We recently received a limited quantity of the TEIN backpacks in orange on a shipment that came in last week.
This may be the only batch of packs to come in this color. So get yours while it lasts!
Part Number- TN018-004-OR
MSRP- $30.00
Available for order from our Online Shop, too!
Just when you thought that something cool couldnt get any better, an even better version comes out. TEIN Japan has taken the already insane EDFC Active and added even more features bringing it to the mind blowing level.
The new EDFC Active Pro controller would offer the same standard functions as the standard EDFC Active, but would add the following features in..
Although it may not seem like much, this would take this kit to a whole new level. The EDFC Active Pro is expected to be released early January in TEIN Japan, and probably around mid March in TEIN USA. Pricing has not yet been finalized but is expected to only be a few hundred more which I feel is worth it. Check back with us on our websites “New Applications” section for up to date info on the release of this new kit.
HAPPY NEW YEAR EVERYONE!!
Here to introduce a new product for the 2014 year. Well it’s a redesign of the EDFC but now with some minor modifications.
The New EDFC II
It now uses a white LED instead of the old Green light it used to have and it is also comes with a new affordable price.
“EDFC II” brings the convenience of in-car damping force adjustment system to the hands of more people than ever. If you are not going to be doing much adjustment or need to fancy high tech EDFC Active then this is the Electronic Dampening Force System for you.
Main EDFC II Features
We’ve already mentioned about the new Defi Advance BF USDM gauges. Now we just wait in anticipation for their arrival on the U.S. shore!
Once again, these gauges differ from the current Advance BF by having readouts in PSI for pressure gauges and Fahrenheit for temperature gauges. You no longer have to attempt converting over metric gauge readings in your head, like some of us had to do!
Current ETA is early January 2014.
We highly suggest you contact your nearest authorized TEIN dealer and get your Defi Advance BF USDM gauges ordered now!
Recently TEIN has been releasing there new updated version of our already popular coilover kits.
The BASIC coilover kit has been updated and released as the STREET BASIS.
The Super Streets have been superseded by the STREET ADVANCE.
And our Flex damper has been superseded by the STREET FLEX.
All of these have been updated with new internal components and some minor changes to the outer portion as well. We’ve also been able to reduce MSRP a significant amount to make it much more affordable for our customers! You can find all the new product information through this link http://www.tein.com/products/index.html
Well now it’s time for the Mono Flex to have a change as well. They have been finding new ways to have one of the best suspensions in the market for a very reasonable price. Starting in 2014 TEIN will be releasing two variations of the MONO Sport.
The MONO SPORT and the MONO SPORT TOURING Coilovers. Both lines will carry our newly designed Upright Strong Tube for strut type suspensions. With this newly design, it reduces friction using a revised internal lubrication method. With this design we are able to have the click assembly for the dampening force adjustment on the top, making the adjustments or installation of the optional EDFC/EDFC Active much easier.
The system still offers the 16 levels of compression and rebound together, but now it is equipped with exclusively-designed “ADVANCE M.S.V.” With the use of “ADVANCE M.S.V.”, damping force adjustable range is made about three times wider, yet superior damping force characteristics are maintained in all parts to improve steering response, road ability and traction performance.
These are just some of the few revisions done to the MONO Sport line for further information on the system please follow this link. http://www.tein.co.jp/e/products/mono_sport.html
