New Products and Developments

Posted on by

With this COVID-19 pandemic throwing us all a helluva curveball, we find ourselves in a very fortunate position to continue our pursuit in bringing some of the best products we can for a wide variety of vehicle applications! We’re continuing to grow, and we couldn’t be happier!

As mentioned, the pandemic wasn’t what we were expecting. In fact, it was quite the opposite of what we were expecting- low to no business, extended lock downs, as well as possibly having to temporarily shut down our operations if things really got worse for all of us.

But, being an automotive parts manufacturer and distributor kept us fully operational ever since we had our lock downs. We have just been very fortunate that COVID-19 has not affected our staff directly. However, the same cannot be said for our parent company and our two factories. Our manufacturing facility in China had to shut down relatively early on in the pandemic. Japan is facing new lock downs due to the spread of the Delta variant. We’re only hoping that, with everyone doing their part, we won’t be faced with harsher lock downs and restrictions.

With that, we’re still facing some struggles. The supply chain has been greatly affected in all aspects and in all industries, and we’re just now catching up on a lot of backordered items for our customers. Freight costs have soared tremendously, not to mention extended transit times or delays for shipments. But yet, we still are trying our best to continue with product development while still being able to service our customers.

So, while we’re still technically trying to catch up, we’ve worked hard to come out with new vehicle applications and broadening our ENDURAPRO & ENDURAPRO PLUS line to reach the European vehicle market, and to-date we’re proud to see this line flourishing. But of course, our coilover lines, our bread and butter if you will, continues to grow as well, with new vehicle applications being added on nearly a monthly basis.

ENDURAPRO Shock Absorbers for BMW X3 and X4 now in stock.
ENDURAPRO Shock Absorbers for Toyota RAV-4 and Lexus NX200t now available.
ENDURAPRO Shock Absorbers for Tesla Model 3 AWD now available (different part numbers RWD Model 3’s also available)

S.TECH Lowering Springs for Tesla Model 3 RWD and AWD available (AWD springs shown.
MONO RACING Coilovers for Nissan GT-R (R35) arriving soon.

Unfortunately posting all the new vehicle and product applications we now have would make this post long-winded and quite boring. So we ask that you please check out our website and search around for what’s new from us!

Also, if it’s more convenient for you, you’re also free to email us at tus_sales@tein.com, or give us a call at 562-861-9161, and we would be glad to assist you in finding products for your vehicle.


A90 Supra Coilovers Arriving Soon!!!

Posted on by

Finally! It’s been an exhausting R&D process in getting a coilover available for the newest Toyota Supra. But now we can say it’s an honest improvement to the OEM suspension.

That was the hiccup in getting our coilovers released in a timely manner. While we had early access to the A90 Supra working with Toyota Motorsports in the U.S., this new platform proved to be difficult in getting to actually improve its performance on just suspension alone. But now, with the help of Japanese sports car tuner Matchless Crowd Racing (MCR), we finally have something to offer!

STREET ADVANCE Z (Part number: GSTJ4-91AS3)

MSRP: $1,200.00

*Front-Right and Rear-Right components shown

After nearly two years of R&D on this car, we’re first releasing our STREET ADVANCE Z coilover kit. At $1200 retail, this kit is a great value in high performance suspension for this new car.

Geez. Two years… Why did it take so long?! We won’t go into all the details. After all, if you’re an A90 Supra owner, we really don’t want to say much to offend you. But since you’re reading this, I’d wager in my assumption that you’re looking to increase the handling performance of your car. So…… In a word, it’s a very difficult car to work with. Don’t take our word for it. If you do a quick search on “MCR A90 Supra” you’ll quickly find that MCR’s owner, Kobayashi-san, really doesn’t like the new Supra. According to him, in translated text, It can’t turn, can’t stop, and is slow. Those are supposed to be aspects that a sports car is good at!

MCR A90 Supra

Take it for whatever it’s worth. I happen to like the A90, but maybe the criticism of this car is just simply a tuner’s standpoint (or marketing point) in order to give the aftermarket something to work with and give the end-user something they “need”, if you know what I mean.

The fact is, the new Supra isn’t priced anywhere near other Japanese supercars like the Acura NSX or Nissan GT-R, and for good reason- it simply isn’t built like those cars. It seems like it was built with aftermarket tuning in mind.

But, it is true- the new Supra is a difficult one. It’s very electronically-laden, much like a lot of high-end sports cars these days. And, again no offense, it is very typical German engineering. That’s not a bad thing. It just takes some time to better understand their design to really improve upon it.

So, what do you get with our A90 STREET ADVANCE Coilover Kit?:


-6kg/mm front springs

-12kg/mm rear springs

-Damping adjustability (16-click rebound) for front and rear dampers

-Rear upper mounts with access holes for damping adjustment

-TEIN Developed Error Canceller Units

-Camber Adjustable Upright Insert

A few things to explain-


Our Error Canceller makes this a plug ‘n play suspension kit by connecting directly to the OEM’s Electronic Suspension control module. Without it, and simply unplugging the OEM dampers will cause a warning on your dash.

Example of TEIN Error Canceller

Our Camber Adjustable Upright Insert is a sleeve between our damper and the aluminum knuckle assembly. By allowing camber adjustment from the bottom of the strut, you can retain the OEM upper mount assembly, which is a good design in reducing NVH.

While installation of our coilovers do void the use of the Factory Electronic Suspension system, you can opt for our optional EDFC ACTIVE or EDFC ACTIVE PRO kit to allow for electronically controlled damping settings.

At last, we finally have a setup that offers true handling performance gains for the new Supra. Better late than never, and better to be well-developed than hastily done, I suppose. Anyway, expect this kit to arrive mid June 2021!

JZA90 Supra Development

Every year a new car release puts us consumers in a tough spot- choosing between a “want” and a “need”. Actually, that’s pretty much the market that TEIN is in. We have a performance product that either a customer simply just wants, or in fact really needs, all depending on what they’re using it for. And for us, just like these new car releases, we have to determine which of our products the customer is going to want, especially for something like the much anticipated new Toyota Supra.

Even on a spec sheet, a stock A90 Supra is a very good package. Of course, as always, the OEM leaves a bit to be desired in many aspects. However, we can see a change in demographic in what they “want” and “need”. Even before the A90 made its way to the consumer, we received inquiries on this platform, mostly with potential owners wanting coilovers. In fact, we got our head start working with Toyota Motorsports as they prepared a couple of A90’s for pace cars to be used at Toyota sponsored events, such as NASCAR races. It was a great opportunity for our in-house engineer to get all the measurements he needs and make a suspension that works well for a pace car, no different than what we’ve done for the Camry pace cars that Toyota Motorsports has worked with us on suspension over the past few years.

Toyota Pace Car

Again, on OEM specs alone, the new A90 Supra is very well equipped. Even though we knew that a “pace car” suspension will never be made as an out-of-the-box setup for our end-users, we had to really think of what, of our products, is the best fit.

A90 Supras have factory electronically controlled suspension. It’s sharing basically all the underpinnings of BMW’s Z4 platform, and BMW technology is found throughout the Supra. So, we know that some consumers are going to want to retain that feature. So first on the list is lowering springs, our S.TECH line specifically.

Next, we knew that coilovers were inevitable. So development on that naturally came next. We’re for sure making a street compliant kit, most likely based around our STREET ADVANCE Z, FLEX Z or FLEX A line. However, the issue is compatibility with the factory electronic solenoids. Much like the FK8 Civic Type R, we’re having to develop our Canceller Units to avoid any issues unplugging these said electronics. This means that the customer can opt for one of our EDFC kits instead of the factory electronics. Yes, that’s an added cost, but our EDFC systems (specifically ACTIVE and ACTIVE PRO) are very advanced and a worthwhile upgrade. Still, we may consider something like our FLEX AVS coilovers which is aimed at Toyotas and Lexus’s using Adaptive Variable Suspension. BUT, this car uses BMW based suspension, and not Toyota’s AVS. So, that will take a bit more time to develop.

On top of making a FLEX type of coilover, we will plan for a more race oriented type setup, most likely around our new MONO RACING coilovers.

Preliminary testing has been completed on production A90’s (the Supra Pace Cars were technically pre-production vehicles, to my understanding). But we’ll still be working on development once other coilover prototypes arrive. So, give us a little time to get these products out!

Evasive Motorsports’ Latest Race Car Project

Posted on by

We are proud to once again work with Evasive Motorsports and their latest project car, an E46 BMW M3. This vehicle will be a dedicated Time Attack vehicle.

Mike Chang of Evasive Motorsports previously used this car as a daily driver. But I imagine, especially after putting in a lot of seat time in their Limited AWD Class CT9A Evolution and Street FR Class AP1 S2000 (of which they both clocked the fastest times in their class at last year’s Super Lap Battle), the E46 certainly found itself a new job in life.

Fortunately for us, we’ve had some experience with the E46 M3, developing a one-off damper kit for use in the Super Taikyu series. In fact, we obtained a set directly from TEIN R&D for Evasive to work with while they dial in their car for track duty. These 3-way adjustable dampers are a far cry from anything street compliant as they are designed for 30+kg/mm springs front and rear. *We are now developing a Super Racing type damper kit for this chassis with rates much more suitable for track conditions we see Stateside. Our in-house engineer Shuichiro will be working side by side with them during this development.

Stay tuned with us and Evasive Motorsports as this vehicle continues to develop throughout the year!
