TEIN Japan Factory Tour with DSPORT Magazine

Never before has a consumer stepped foot into the TEIN factory, ever!

TEIN Japan New Facility (Jan 4, 2016) 007 blog

As you can imagine, TEIN (as with many other manufacturers) has some proprietary methods for manufacturing shock absorbers, with several processes pioneered in-house. In fact, there are some machines developed specifically by TEIN engineers solely for our own use. So, to show that to the public may be detrimental to us since we do not want such information to be released to the public. This is information that can reach another suspension manufacturer!!!

However, there is a benefit to showing consumers what TEIN does and what we’re capable of. For one, it’s a sign that TEIN is confident in our technology. Second, consumers are just as interested in seeing how their products are made. So why not show them?!

Well, that’s exactly what we did! We worked with DSPORT magazine to arrange a tour of our facility during their Tokyo Auto Salon guest tour for this year.

Every year, DSPORT Magazine arranges a tour package for interested people. For about $3,500/person, guests get to take a trip to Japan and visit Tokyo Auto Salon and several Japanese performance parts manufacturers’ facilities. So it sounded like a prime opportunity to have TEIN show the public our factory.

We felt bad for our guests, though. The day before was to be a trip to Fuji Speedway. But, due to bad weather the event was canceled. We were hoping our tour would make up for that missed event!

We had just over 40 guests for our tour on January 19th.

Prior to the tour, we gave our visitors a general overview of our property, including our offices, R&D facilities, Quality Assurance facility, and manufacturing.

Since it was a fairly large group for us, we had split up the group among 8 tour guides.

Below are a few pics of the factory’s facilities and processes. Again, we have to limit what we can show the public. Sorry:

Our Materials Yard, where we keep inventory of parts to prepare for manufacturing our suspension.

ALUMINUM BILLET GRADES

Other than steel components, we also use aluminum alloys. We stock three grades of aluminum billets, each one to be used depending on the application and use. For aluminum damper shell cases, we use an A 7050 grade extruded tube, however.

BAND SAW FOR BILLET

Aluminum billets are cut into smaller billet blanks using either our band saw or circular saw.

A sampling of some of the suspension components our lathes can process, from prototype to finished product.

TEIN Japan New Facility (Jan 4, 2016 021

Some of our components are machined from billet blanks, which we cut from larger bar stock, using various grades of steel and aluminum depending on the product requirements. These steel pucks will end up becoming our pillowball cases for strut type upper mounts.

TEIN Japan New Facility (Jan 4, 2016 059

We use tubing of various sizes to make damper shell cases to lower brackets for full-length adjustable dampers.

TEIN Japan New Facility (Jan 4, 2016 076

Lower brackets, after any necessary welding, go through shot blasting prior to any surface coatings.

TEIN Japan New Facility (Jan 4, 2016 050

Semi finished piston rods that have just been gun drilled (for damping adjustable suspension applications). Still a few more steps to being completed sub assemblies.

NC LATHE

We have many lathes to handle different processes, such as piston rod machining. Here, threads being cut for piston valve assembly.

PISTON ROD INSPECTION

Vital for our piston shafts is our high-resolution inspection machine. It is capable of detecting even the slightest flaw on the piston shaft surface. Each and every piston shaft is inspected. If defects are found, we must discard the shaft.

Our Swiss Precision Lathes help create small damper components like our ADJ Needles. Such small parts require great detail, which this machine can do consistently. It also runs nearly non-stop!!!

NEEDLE STOPPER

A finished batch of our ADJ Needle Stoppers out from the Swiss Precision Lathes.

LASER CUTTING

A recent addition to our factory is this Laser Cutting Machine, capable of cutting steel up to 16mm thick using a carbon dioxide laser beam. Quite a fast and efficient process!

LASER CUTTING 2

Here’s the Laser Cutter in action, cutting our camber plates for strut type pillowball upper mounts.

SHOT BLASTING

The second floor of our factory handles our surface coating stages. First, we shot blast our steel components. This allows our powdercoatings to adhere better to the steel bodies.

POWDER PAINTING

After shot blasting, some shell cases go through our patented 2-Layer/1-Bake powder coating process, where zinc powder is first applied, followed by our trademark green powder paint, then cured.

PACKAGING

After final assembly, kits are packaged up and shipped out!

 

While a couple groups went out for the factory tour, we also set up a test drive so visitors can try our new FLEX A dampers and EDFC ACTIVE PRO on a Toyota Vellfire.

The tour went faster than expected, and considering the factory was in full swing when we had it, it was difficult to hang around the machinery for very long with TEIN staff trying to navigate around us.. We even had to speed through some demonstrations by factory staff. Fortunately we were able to showcase a lot of our machinery and even some prototypes.

Afterwards, we took our guests out for a sushi lunch.

Overall, it looked to be a fun experience for our guests. I got to speak with several of them and they were all impressed with our manufacturing. So many people wanted to purchase TEIN suspension kits right away!!! Lol. I felt bad that we couldn’t arrange any suspension purchases while we were there, but I’ll be taking care of them on their return to the U.S.!

Thanks for stopping by, guys!!!!

 

JCCS THIS WEEKEND (Sept. 19, 2015)!!!

It will be our fourth consecutive year attending the Japanese Classic Car Show (JCCS) out by the Queen Mary in Long Beach, CA! Event starts at 9a and goes until 3p and is free to the public!!!

Japanese Classic Car Show Website

While not known for really being related to older vehicles, we do have our Specialized Damper Program. This is the perfect program for such vintage vehicles that no longer have a strong aftermarket support program. We’ve used this for many older vehicles in Japan, and it continues to grow Stateside!

DSC_1861 resize

Apologies, but we didn’t have a Japanese classic last year. Hopefully this year??

Anyway, we’ll have our booth setup with TEIN goods for sale. We hope to see plenty of you there!!!!!

DrivingLine.com Gets a TEIN Overhaul

Like that title picture??? Pretty gross, and this is what can happen when you wait to long to service your TEIN dampers! LOL. Actually, that’d be more like worst-case scenario.

We recently got to work with Jonathan Wong of Driving Line, an online magazine focusing on all aspects automotive related.

Several years back, when Jonathan was still at Super Street magazine, we had provided him some of our SS-P coilovers for his ED Civic Hatchback project, a vehicle that he wanted to maintain a lot of JDM appeal. During that time, we had revalved the dampers for more track use.

 

DL-TEIN-EDIT-8

Now, Jonathan uses the car for occasional street use, and comfort is more of a concern than track-like handling. It was an ideal time for him to come in, get his dampers revalved, and also see what that type of service entails. *The title picture isn’t his actual damper, btw. He does a good job of maintaining his ride.

DL-TEIN-EDIT-5

DL-TEIN-EDIT-7

Although we talk quite a bit about our overhaul service, Jonathan points out something very true- not a lot of customers are aware of this service. With some of the new coilover lines we’re introducing, such as the FLEX Z, STREET ADVANCE Z, & STREET BASIS Z, which don’t require rebuilds, chances are that customers will never really know what else we can do with our existing products. It isn’t uncommon for customers to get our kits second-hand, and most don’t know much about our brand after that.

As for all TEIN suspension owners out there, we must mention that there is no set rule for when a damper should be sent in for servicing. Some customers may send in their set well before 30,000 miles of use. We’ve seen others come in with well over 100,000 miles of use. We do recommend inspecting your suspension every 30k miles, though. Really, it’s up to the customer to inspect and maintain their suspension. Surprisingly enough, simply keeping the dampers clean may extend the life of the dampers. An area prone to causing damper leaks is at the top of the damper body (not the piston shaft). At the top of the damper body is a dust seal where the piston shaft slides past as it functions. Spraying this area with water, or even with WD-40 or something similar, helps keep the dust seal debris-free and prevents it from getting damaged and eventually leaking any of the gas charge. Doing this also keeps the piston shaft from scoring from such debris. A damaged piston shaft can be anywhere from $40 and up depending on the model (on top of the base overhaul fee).  If you’re doing this type of maintenance, it’s also good to inspect the rubber dust boot and polyurethane bump stop for any damage. They can easily be replaced and are a good insurance to maintaining a long lasting damper.

Here’s R&D Assistant Chris A. disassembling a FLEX damper for service.

We’re glad that Jonathan was able to see himself what we could do. Definitely some good insight for customers with our products and to know what we can do for them!!!

Japanese Spec Vs. US Spec Coil-overs

Recently I have noticed that a lot of consumers and dealers of ours inquire about the differences between a Japanese-spec coilover kit and a U.S.-spec coilover kit. Relax, grab a cup of coffee, and let me do some explaining. It’s actually quite simple.

One of the main differences between these kits is the valving and in some cases spring rates. The U.S.-spec coilover kit comes with a more aggressive valving. The reason behind this is because consumers in the U.S. prefer a slightly more aggressive coilover in comparison to consumers in Japan. U.S. vehicle’s may also have some manufacturing differences opposed to the ones released overseas.

But as mentioned earlier, another factor is the spring rates. Some of the U.S.-spec coilover’s come with a stiffer spring to match the aggressive valving of the dampers. Of course there are other differences between the dampers besides the valving and spring rate. Damper designs may vary from U.S. to Japanese kits such as damper mounting points, damper body and stroke lengths, and required OEM parts.

As a side note- some U.S. applications may be compatible with Japanese dampers with no modifications whatsoever. But we recommended to verify with TEIN prior to purchasing these kits.

In conclusion, regardless if the coilover kit is Japanese or US spec they both come down to one thing- they both cater to different markets which is a matter of consumer preference. However, TEIN is able to assist with customization of your TEIN dampers through our Overhaul and Revalving service available Stateside through our in-house service departments in the East Coast and West Coast facilities. As a performance suspension manufacturer for a global market, we realize it is difficult to appease all customers. But we can definitely assist our customers in dialing in their suspension for their specific needs, all of which is for your driving pleasure!

JDM MINI VANS

I have been asking my co-workers in Japan what are the hot new cars and they always say that the most popular applications for TEIN Japan are for Mini Vans. I couldn’t believe it. Why would people buy a Mini Van when they can get used Type R, Skyline, S15, S13/14 with OEM SR20DET, GC8 STI, etc… for good prices. They tell me that younger generations are not as interested in speed, power and handling as past generations. Young people want convenience, comfort, good gas mileage, storage space, etc… Sounds like my dad. So I decided to look into the JDM mini vans and here is what I found.

Honda StepWagon RG1

This is the Honda StepWagon. Not a fan but it is actually one of the most popular mini vans in Japan. Since Japan is small and the roads are tight, many new cars are built taller to provide more room. If the car is too wide it has limited areas to park and is hard to drive on narrow residential streets. Already on its fourth generation. Automatic sliding doors on both sides, K20 or K24 power and CVT.

Toyota Estima ACR50W

These smaller mini vans look more like wagons then vans. They even have a hard time out in Japan trying to classify these vehicles, but they finally just classified them as mini vans. This is the Toyota Estima which is the JDM name for Previa. Ultra popular with available V6, sliding second row seats with foot rest, power folding third row, etc…

Toyota Vellfire GGH20W

This Toyota Vellfire (variant of Alphard) is considered a full-size “mini van.” To me it looks like a bug with two separate set of eyes. For some of you out there, you might be asking yourselves why does this car have two sets of headlights. Well it seems that it was just a design change for the Vellfire version. One is actually for High Beams and the other for regular headlights. This is a baller mini van. Features include voice navigation, blind corner monitor, self parking system, auto cruise, lane monitoring system, etc… the thing almost drives itself. Price tag can go up around $60K.

This is a decently popular model and the only one out of all the mini vans in this post that I would actually consider purchasing, a Honda Stream. (I’m not a fan of big cars, I drive a CR-X). The higher end model comes with 2.0L, 150HP, CVT with paddle shifters. Sits 5 and has plenty of space for my pitbull, Mykaela.

Honda Stream RN6

These are just some of the mini vans that they have in Japan. TEIN develops many coilovers for these applications including Basic Wagon, Super Wagon, Basic Flex Wagon, Super Flex Wagon, Super Flex Wagon SUPER LOW DOWN, GT Wagon and Hybrid Wagon Damper (Hydraulic Ride Height Adjustment).  The mini van applications are the best sellers in Japan. These coilovers can be purchased through any of our authorized dealers as a special order but unfortunately they would not fit anything here in the US.

Made Specifically for TEIN USA

TEIN products are developed, tested and produced exclusively for the region in which they are sold. Not every region has different specifications but North America does.

Not every model (BASIC, SS, Super Drift, Super Racing, etc…) has a region specific setup. Product models like Comfort Sport or Super Racing serve niche markets and are therefore universal for the world. A competition car using semi-slicks is similar in the US and in Japan., therefore the same product is sold.

Both Cyber EVO and Evasive use Super Racing coilovers.

HOWEVER, models such as BASIC, SS, SS-P, FLEX and Mono FLEX which are more for street use are made specifically for TEIN USA (North America). Meaning a Mono Flex coilover for a 2008+ Subaru STI sold in the US is different than the kit sold in Japan. Features, materials, basic design, assembly, etc… are all the same but mainly spring rate, valving, and ride height range are different.

TEIN USA Kit:  GSS84-FUSS1

Spring Rates Ft: 10kg, Rr: 8kg

Recommended Ride Height Ft: -1.4″, Rr: -1.2″

TEIN Japan Kit:GSS78-F1SS1

Spring Rates Ft: 7kg, Rr: 5kg

Recommended Ride Height Ft: -0.8″, Rr: -0.6″

The specific differences may include spring rate/length, damping force, piston stroke, shell case length and brackets for brake lines, ABS, etc… Products are setup differently because the cars are NOT the same and more importantly the customers are not the same. Admittedly US consumers follow most trends from Japan especially when it comes to performance. However in Japan, the majority of consumers want more compliant suspension systems (softer setups) and do not want the car to be too low. Additional, vehicle ride height laws differ from country to country and in the US state to state.

You can see the difference in ride height between the US Civic Si with JDM body work and real JDM Civic Type R.

In general, TEIN USA setup products with stiffer spring rates and more drop in comparison to TEIN Japan. This is true for both coilovers and lowering springs. For TEIN USA our coilovers setup has changed over the years to keep in tune with the ever changing consumer demand. Our more recent kits have become a little softer than the products which were developed 6-7 years ago but that information is for another blog entry.

On a side note – if any US or Canadian customer wants a TEIN Japan spec. kit we can special order those upon request.
