Honda CR-Z Sport Hybrid Testing

Posted on by

Product testing for the Honda CR-Z Sport Hybrid, the highly anticipated successor to the CR-X, has been completed.

H.Tech Lowering Springs & Super Street Coilovers.

The H.Tech Springs will provide a drop of: Front -20mm and Rear -25mm

The Super Street Coilovers will provide a drop of: Front -35mm and Rear -40mm

Drop quantities at this time are only approximations, as Honda has yet to provide information on different Grades, Packages, Equipment, etc.

The CR-Z when it first entered the garage. Almost time for us to begin removing and disassembling the suspension.

With the H.Tech Lowering Springs installed the CR-Z is already looking better.

For those that desire a more aggressive stance and slightly sportier ride quality over the stock suspension.

Riding on Super Street Coilovers the CR-Z now truly looks like a Sport Hybrid.

This product not only provides an aggressive drop, it also has a much sportier feel that won’t compromise your comfort.

These products will arrive on our shelves and be available for purchase very soon.

Ongoing Projects

Posted on by

Looking in the R&D section today there are quite a few cars.

TEIN Mustang – sitting up on the lift awaiting repairs to the motor. I guess making nearly 500WHP took its toll on the motor.

0-60 magazine Rally Scion xD – down below awaiting completion of repairs after Rally Maine. The huge rocks caused a lot of damage on the underside of the car including a dented oil pan, heavily damaged belly pans and damaged one rear shock.

EVO 9 – finishing up installation of new DEFI gauges and Devil’s Own Alcohol Injection system.

WrapTivo/ Import Tuner magazine Honda CR-Z – arrived this morning. RJ De Vera’s latest project vehicle for SEMA. We will be test fitting lowering springs and Super Street coilovers. Look for a future post with more information.

TEIN/ Import Tuner magazine Lexus ISF – sitting outside awaiting pickup. Finished giving the car an inspection before Import Tuner chief editor, Carter Jung, takes it up to Nor Cal for Targa Trophy. Should be fun with over 500WHP when on the bottle.

R&D Test Cars Needed.

Posted on by

Blog readers, greetings from the Tein USA Research and Development Section.

In the past, a majority of the blog posts done by R&D have been on vehicles which we had finished our testing on. We simply wanted to report on future products that you, the consumers, could look forward to.

As of late, however, we in R&D have run into a problem. We no longer have test cars to do testing on.

You see, with the continual release of new vehicles and models, there is no way for us to constantly look to just a few sources to provide us with these vehicles to do testing on.

We are completely reliant upon the consumers and enthusiasts, like yourself, to provide us with their personal vehicles to do the aforementioned testing on.

About the Testing itself:

Depending on the testing and the products being tested, the time frame that we require your vehicle for is usually 3-5 days.

Thinking of being without a vehicle for a bit of time may be a huge deterrent for many.

However, look on the bright side.

Free Suspension! Depending on the application, you may walk out with our lowering springs or you may walk out with  a set of our coilovers.

The installation will be professionally done by the R&D Engineers.


After the installation is finished we will perform a Basic Front-End Alignment and you’ll also be the first person to own the product.

If that sparks your interest and if you have the time to allow us with your vehicle, then check out this link and find out if your car is one of those that we are looking for. If you happen not to find your car on the list, no need to fret, check back every once in a while and we just may be in need of your car sometime down the line.

08+ Nissan Altima Coupe 3.5 Lowering Springs

Posted on by

Lowering Spring testing for the 08+ Nissan Altima Coupe 3.5L V6 Cylinder models has been completed.

The S.Tech Springs, which will be available shortly, for the 3.5L V6 models.

The ride height drop for the 3.5L V6: Front -50mm and Rear -50mm,

The actual drop may vary by models due to the weight of different components (ie Transmission, Packages, etc.)

We will also be conducting Lowering Spring testing on the 2.5L I4 Coupe, 2.5L I4 Sedan, & 3.5L V6 Sedan soon.

2010 2.5 Subaru Legacy Lowering Springs

Posted on by

S.Tech Spring testing on the 2010 2.5 Subaru Legacy has been completed.

Expect the ride height drop to be: Front -45mm and Rear -40mm

The actual drop may vary by models due to the weight of different components (ie Transmission, Packages, etc.)

Expect Mass Production units to be ready for sale in about 4 months time.

We will be testing Lowering Springs on the 3.6 Legacy soon.

We will also be testing coilovers in the near future.

2010 Mazda 3 Lowering Springs

Posted on by

S.Tech Spring testing on the 2010 Mazda 3 has been completed.

For testing we used currently available TEIN Japan High.Tech Lowering Springs (gold colored springs).

The final US Spec S.Techs will be available sometime in the Summer of 2010. The specification will differ from the TEIN Japan spec springs we used for testing due to the differences between the US and JDM model vehicle.

Expect the ride height drop to be: Front -40mm and Rear -40mm

The actual drop may vary by models due to the weight of different components (ie Transmission, Packages, etc.)

We take measurements at all positions of Compression and Rebound with and without the tires installed.

Above we have the tire installed and damper fully compressed to check for any clearance issues. Our products do lower your vehicle a considerable amount as compared to stock and we wouldn’t want any unnecessary damage to occur due to too low of a ride or too little clearance between parts.

Note: these are the Japanese Spec Lowering Springs, our final US Spec S.Techs will be Green.

2009 Mitsubishi Lancer GTS

Posted on by

S.Tech Spring testing on the 2009 2.4L Mitsubishi Lancer GTS has been completed.

The S.Tech Springs Part # SKE20-AUB00, which have been available for other Lancer models, are now approved for use on the GTS as well.

The ride height drop for the Lancer GTS: Front -51mm and Rear -30mm

The actual drop may vary by models due to the weight of different components (ie Transmission, Packages, etc.)

You too can have an aggressive drop that changes the image of the entire car, at a cost that won’t hurt your wallet. Contact you local Tein Dealer. http://www.tein.com/dealer_list/index.html

2010 V6 Acura TSX

Posted on by

Testing on the 2010 3.5L Acura TSX has been completed.

Basic Coilovers (Part # DSB90-LUSS2) and Super Street Coilovers (Part # DSB90-KUSS2) are Now Available.
These part numbers will fit both 3.5L V6 and 2.4L I4 models.

The ride height drop for the 3.5L V6: Front -36mm and Rear -35mm

The ride height drop for the 2.4L I4: Front -39mm and Rear -36mm

The actual drop may vary by models due to the weight of different components (ie Transmission, Technology Package, etc.)

You will notice the dampers have been installed without the Springs, Bump Rubbers, and Dust Boots.
During one of our testing phases we check for the best possible ride height and clearance issues with our products and any of the vehicle’s suspension components, by taking measurements at various conditions of damper rebound and compression.

Here the car sits at recommended height with the OEM wheels. The tires tuck nicely giving an aggressive look.

Thanks to Honda Tuning magazine for letting us borrow their latest project vehicle. Be sure to check their website and issues when they hit the newsstand.
