2022 Subaru BRZ Products

Featured

Posted on January 21, 2022 by Paul P.

We’re glad to report that, for the most part, existing coilovers for the Subaru BRZ will in fact work fine with the latest 2022 BRZ body style (ZD8 chassis code).

So, we’re listing our FLEX Z (VSQ54-CUSS4) and FLEX A (VSTD8-D1SS4) as compatible for both first and this second generation BRZ.

However, our STREET BASIS Z, STREET ADVANCE Z, and our S.TECH & HIGH TECH lowering springs will have new part numbers.

As to why our existing FLEX Z and FLEX A coilover lines are still compatible- the spring rate and valving work very well on the new platform. But, these coilovers are a bit more aggressive than the STREET BASIS Z & STREET ADVANCE Z lines. Therefore, we’ll have to determine what changes we’ll need to make for these kits. As well, our S.TECH & HIGH TECH springs will be unique for this car due to different lengths and spring rates.

The only issue now, really, is the supply chain, as we’re still experiencing massive delays in imported goods from Japan.

Currently, the FLEX Z and FLEX A coilovers have an eta of late February 2022, while the HIGH TECH springs have an eta of April 2022.

TEIN MONO RACING Coilovers

Posted on December 20, 2019 by Paul P.

While we still sell plenty of our FLEX Z and MONO SPORT coilover kits, and since they fit the bill for most consumer’s needs, we feel and also see the need for more race-oriented suspension setups. To date, we still produce our SUPER RACING coilover line for those needing a setup to match more aggressive chassis and tire setups people use for road racing and the ever-so-popular Time Attack races. However, for some, there is no necessity of 2-way damping adjustability. In fact, for some consumers, having that extra adjustment (separate compression and rebound damping), might be confusing. Again, probably why we still sell plenty of FLEX Z and MONO SPORT coilover. There’s a certain simplicity to these coilovers.

But, in between a MONO SPORT or SUPER RACING coilovers is a bit of a gap. This led to our development and release of the new MONO RACING coilover line.

MONO RACING coilovers take all of the features of the MONO SPORT line- monotube construction (with our proprietary “Strong Upright Tube” setup for strut suspensions), threaded shock body (for separate spring preload and ride height adjustments, and use of our Micro Speed Valve (M.S.V.) for improved low-speed damping control. With that, we add some features of the Super Racing line, mainly items for strut type applications, such as camber/caster adjustable front upper mounts and extra camber adjustment at the lower bracket (camber washer). Along with those features, we valve the MONO RACING dampers far more aggressive and include stiffer springs, making the package a much more race oriented feel. Damping adjustment is rebound only (16-click, like our typical coilovers), and is of course compatible with our EDFC systems. Like all TEIN coilovers, we still treat the MONO RACING coilovers to our proprietary ZT and powdercoating for long-lasting durability. MONO RACING coilovers are also serviceable (rebuild and valving) and customizable.

Again, the setup is aimed towards consumers who done vehicle modifications that are complimentary to a track setup. Typically a very good summer tire or even R-compound will work well with this suspension package, but also other additions like small aero upgrades can take good advantage of the more aggressive damper and spring setup.

Most importantly, we wanted to bring this user-friendly race coilover kit at a reasonable price point, starting at $1800 and going up to $2220, all depending on the vehicle application (strut type or independent spring/shock type suspensions are more expensive).

Now available for the following applications:

Honda Civic Type R (FK8) *includes Error Canceller Units

Toyota 86 (Scion FRS)/Subaru BRZ

Mazda Miata (NA6C/NA8C/NB8C/NDERC)

Mitsubishi Lancer Evolutions VII/VIII/IX (CT9A) and X (CZ4A)

Subaru WRX/STI (GDBE/GRF/GVF/VA

and more applications to come.

2017+ 86 & BRZ FLEX Z, FLEX A, & MONO SPORT Coilover Testing

Posted on June 28, 2017 by Paul P.

We just finished up some testing on the 2017 Subaru BRZ (and which would of course affect the 2017 Toyota 86). While the vehicles aren’t drastically different compared to 2012-2016 model years of the aforementioned vehicles (the 86 previously named the Scion FR-S), there are some small changes in suspension that affect how our existing coilovers feel.

TEIN Japan currently sells part numbers VSTD8-C1SS4 for the FLEX Z line, VSTD-D1SS4 for the FLEX A line, & GSTD8-71SS4 for the MONO SPORT line for their market.

Stateside, we currently sell the VSQ54-C1SS4 for FLEX Z and GSQ54-71SS1 for the MONO SPORT line. For the FLEX A, we previously sold the VSQ54-D1SS4 model number. Now we sell the VSTD8-D1SS4. For the MONO SPORT line, we’re looking to start selling TEIN Japan’s GSTD8-71SS1, since there isn’t much variation between the U.S. and JDM spec.

Phew, that’s a lot of part numbers…..

So, why the change to FLEX A part number VSTD8-D1SS4?

The reason is that there are a lot of similarities between the U.S. part numbers for FLEX A and FLEX Z. If you’re not familiar with either, we’ll just say that the FLEX A includes our proprietary Hydraulic Bump Stop (H.B.S.) and is also a serviceable damper (can be rebuilt/revalved). In terms of cost, the FLEX A is $210 more.

Since the features are really the only noticeable difference, we had to look at damping force between the JDM and US kits to see what would work best for our market. The U.S.-spec FLEX A and FLEX Z both had very similar damping characteristics. Aside from the H.B.S. setup in the FLEX A’s, they feel nearly identical.

With that said, we wanted there to be difference between the two kits. Something that will help differentiate the two when a customer decides what they’ll be using the kit for.

So, we recently started offering the newer part number of FLEX A, the JDM version, part number VSTD8-D1SS4. These actually have a difference in damping, being more aggressive. We feel this may end up being a better option for the more-than-occasional track driven car owner. Being a serviceable damper, this also will allow owners the ability to revalve the dampers for different spring rates, if necessary. Along with being slightly more aggressive, the damping adjustment range is shifted up slightly, giving the end-user a higher range of tuning flexibility at the track.

That’s not to say that the FLEX Z isn’t at all capable of track use. However, we wanted this setup to offer greater compliance for a daily commuter, while still having an available adjustment range that allows for much more sportier handling characteristics. Comfort was just more of our aim for this kit, and it is greatly noticeable on larger bumps as high-speed compression is softer and more forgiving.

FLEX Z and FLEX A coilovers will look nearly identical. But, as mentioned in this blog, there are some features that FLEX A has over the Z line: Hydraulic Bump Stop, serviceable dampers (rebuild/revalve), and slightly more aggressive valving out of the box.

So, as far as a total breakdown of each suspension offering we have for the FR-S/86/BRZ:

STREET BASIS Z (GSQ54-8USS2)– perfect for daily driver not looking to sacrifice OE ride feel but improve handling performance, while being ride height adjustable.

FLEX Z (VSQ54-C1SS4)– high performance street kit, with 16-click damping adjustment and included upper mounts (camber adjustable for front).

FLEX A (VSTD8-D1SS4)– higher performance street kit/occasional track kit with aggressive damper valving, but with a greater adjustment range for ease of tuning. Included Hydraulic Bump Stop (H.B.S.) providing greater control and damping stability against repulsive compression force. Includes upper mounts as well (camber adjustable for front).

MONO SPORT (GSTD8-71SS1)– entry-level race setup with single adjustable damping. Monotube internal structure with greater oil capacity for better endurance and performance for long track stints. Also utilizes are Micro Speed Valve (M.S.V.) to improve low-speed damping curve. Includes upper mounts as well (camber adjustable for front).

SUPER RACING (DSQ54-81LS1)– 2-way damping adjustable setup for dedicated track cars, suitable for cars with R-compound or softer tires. Lightweight (full aluminum rear damper assembly), and included duralumin upper mounts (camber & caster adjustable for front) and camber washers for front.

Hopefully this info helps. If not, you’re more than welcome to give us a call to discuss your suspension options!

Moto IQ’s Project VAF Subaru WRX

Posted on December 7, 2015 by Paul P.

One of the biggest things for the TEIN group this year was the introduction of our FLEX Z dampers. A new product line starting at well under $1000 (starting at $800, to be exact!), and with most all of the same features as the existing STREET FLEX dampers, we figured it would be a good hit for us! What we didn’t anticipate was how well it would be doing. Now we’re running into an inventory problem for some of the most popular applications. Please know that we’ll do our best to get our kits to you, our anxious customers!!! Thank you for your patience!!!

Anyway, what we wanted to post about was MotoIQ’s Project VA Subaru WRX. We recently supplied them with a set of our FLEX Z dampers. This vehicle’s modifications are fairly mild, with a strong emphasis in trying to maintain good driveability for the street but with weekend warrior capabilities.

This project’s aim made it a perfect candidate for our FLEX Z dampers. This recently released item has been set up to offer great handling and comfort for street use. We wanted this exact emphasis to be shown. Along with the mods that MotoIQ has already done (Polyurethane bushings, sway bars, big brakes, larger & wider wheels and tires, and a small gain in power), the FLEX Z’s will make for great build!

For those not yet familiar with the FLEX Z line, it is essentially a STREET FLEX damper kit- full-length adjustable for separate spring preload and ride height adjustment, 16-way damping adjustable using our ADVANCE NEEDLE technology, included upper mounts for front and rear (camber adjustable for the WRX), as well as EDFC series compatible. What differentiates the FLEX Z from its big brother is that the FLEX Z uses fully sealed dampers. This makes them non-rebuildable. However, we can still service the dampers by providing customers with replacement dampers that they can purchase through authorized dealers.

Although we cannot rebuild them, customers can request custom valved FLEX Z kits or custom valved replacement dampers which TEIN Japan can manufacture for us (ETA ~8 weeks).

Other than that one difference between the STREET FLEX line, the FLEX Z’s have been valved to be less harsh in comparison to our previous FLEX damper lineups. We did this because we know that customers looking for this type of setup, especially one under $1k, still maintain their vehicles for road use/daily driving. Having an affordable damper kit that rides like our N1 dampers, which sounds kinda cool to some, may not sell very well for us. However, the use of our ADVANCE NEEDLE technology gives the customers a wide range of tuning possibilities for handling such various road conditions. It truly offers a night and day difference from the softest to the stiffest damping settings.

Read more on our new FLEX Z line here.

Again, thinking of what the MotoIQ guys had in mind for their VA WRX project, we feel we’ve paired them up to the kit that matches their needs.

Keep posted with MotoIQ as this project progresses!!!

MotoIQ’s Top 13 Tuner Cars of SEMA

Posted on November 24, 2015 by Paul P.

Once again we’re proud to see some TEIN equipped vehicles to make MotoIQ’s list of top tuner cars of SEMA 2015! One of them, Evasive Motorsports’ Nissan GT-R, happened to be our booth car for the show (OH, DID YOU KNOW THAT ALREADY?! ;)). That’s definitely something for us to be proud of! Evasive’s GT-R uses our Super Racing dampers (which also has our 3-way unit for low-speed and high-speed compression adjustment) and EDFC ACTIVE PRO.

Another vehicle to make the list was Whiteline USA’s Scion FR-S owned by Jonathan Polidano, Technical Sales Manager for Whiteline USA. He’s using our MONOSPORT dampers and EDFC ACTIVE PRO.

While we took no part in physically building these two cars, we are honored to have our engineered suspension grace these builds. Evasive Motorsports plans to use the car for local Time Attack events in California (and possible out of state events), while Jonathan Polidano plans to use his FR-S for NASA series events. Make no mistake, neither of these cars were meant to be show cars!

Congrats to Evasive Motorsports and Whiteline USA! We’re certainly glad to be a part of your beautiful cars!!!

Our In-House Engineer’s personal Scion FR-S

Posted on March 20, 2015 by Paul P.

While most of us are pretty much desk jockeys here at TEIN USA (just kidding!), some of our staff enjoy spending their free time at the local race track. Local to us southern Californians is something like a 1 hour drive on average.

One such racing enthusiast is our very own in-house engineer, Shuichiro (a.k.a.- “GQ”). He occasionally takes one of his daily drivers to the track. He’s currently driving his 2013 Scion FR-S. Prior to this, he had a well-prepared Honda S2000. However, there was one occassion where he tried to get all environmentally friendly and drive a Toyota Prius. Dunno what he was trying to do there. He was probably all like “I wanna be like Brad Pitt” or something. Don’t get me wrong, he’s still a true race enthusiast. That hybrid car stuff was just a phase we’re trying to forget about…

He was told to “look natural”. This is his idea of “natural”. So GQ.

But yes, he’s an enthusiasts. Whenever he has the chance, he’ll prepare his car for track duty. Being that he works at TEIN, that means he has access to any one of our suspension kits.

We are actually making his car our guinea pig for damper development, for both new product and experimental damper valving. Since it is easier to do so with our 2-way adjustable setups, we have him run our Super Racing coilover. Not a bad hookup for making him our crash test dummy! I mean, test driver. In the name of science!!!

The current build sheet for his FR-S is as follows:

*Exterior
Front lip spoiler: Revolution
Side skirt: Downforce Evasive (exclusive model)
GT wing: Voltex Type1S
Duck bill: Five Axis
Fender Spoiler: TRD

*Interior
Seat: Recaro SP-G
Harness: TAKATA Race 4

*Footwork
Coilover: TEIN SRC (Ft9kg/Rr10kg)
Wheel: Advan GT 18×9.5 +40
Brakes: AP Racing front big brake kit w/ 6 piston calipers
Brake pads: Project Mu

*Drive train
LSD: ATS&Across

*Engine
Intake: Revolution
Throttle Body: Revolution
Exhaust manifold: Fujitsubo SuperEX
Front pipe: Berk
Cat back: Fujitsubo Authorize R Type S (w/ burnt tip)
Oil cooler: Greddy
ECU: Ecutek

A very simple build. Nothing too over-the-top, and definitely a good platform for us to continue damper development on. In fact, the FR-S/BRZ has been one of the best selling of new vehicle platforms for us in terms of suspension sales!

So, if you see him at events, especially around Buttonwillow, don’t hesitate to say hi to him. Better yet, prepare a bunch of technical questions to ask him in case you run into him! He loves that kind of stuff. Apparently.

Ziptie Dynowerks Reviews STREET FLEX Dampers for Subaru Legacy Outback

Posted on December 11, 2014 by Paul P.

You read that right- a Subaru Outback. We actually never fitted our suspension on the Outback variant of any Subaru, Legacy or Impreza. We are aware of the various differences there are, mainly the overall ride height being much higher on these models. However, all suspension pick-up points seem to be the same.

Ryan and George from Ziptie Dynowerks contacted us with a rush request. One of their guys at the shop needed suspension for his Subaru Legacy Outback for a weekend track day event. This was on Wednesday, so we had to get the kit out to them as soon as possible.

After all was said and done, they decided to put up a nice review on our product! We appreciate getting this from them! Check it out when you have a chance!!!

Not your average Subaru Legacy!!!

If you have questions regarding suspension options for a Subaru Legacy Outback, Ziptie Dynowerks are your go-to guys and can give to the rundown of what you need, what will work, and what can work with a little finesse!

Carbing Tower Bar for Scion FR-S (and Subaru BRZ)

Posted on September 19, 2014 by Paul P.

Our in-house engineer, Shuichiro (a.k.a. “Shu”, for simplicity’s sake), has a bit of a tuning bug. He can’t seem to leave any of his cars alone. With the exception being that Toyota Prius he had for about a half year. Word on the street is he’s modifying a baby stroller for his daughter. Supposed to have TEIN coilovers with EDFC Active Pro and 5″ TE37’s? Oh, dear Jesus Gonzalez…

Seriously, I think he’s literally a kid in an automotive candy store. Him working here is a bad idea. Then again, he’s also our guinea pig for testing some of the latest parts. So, that’s technically good news for you, the consumer!

He recently purchased some Carbing Tower Bars for his Scion FR-S, which already has a gamut of parts (TEIN Mono Flex with custom front knuckle brackets, Fujitsubo Legalis R exhaust, and several other performance parts- no big power adders, though). I dig the Volk TE37 Time Attack’s he’s bolted onto each hub. Them wheels es muy sexy.

Prior to his Carbing purchase, we only special ordered these parts for a few customers. So we had no idea on fitment for the U.S. FR-S.

Anyway, here’s a pic of the Tower Bars installed.

You’re actually looking at two Carbing Tower Bar items in the picture.

Strut Tower Bar (in steel; painted white)

Part #: CA 611 055 0

MSRP- $170

Tower Brace (V-Bracing; in steel; painted white)

Part #: CA 693 055 0

MSRP- $160

No modifications necessary to install. Simple bolt-on. The Tower Brace (V-bracing) replaces the factory stamped pieces and bolts to the same factory mounting positions.

We currently stock both items here. So any authorized TEIN dealer can get them for you right away (since we’re the North American distributor for Carbing)!

And yeah, Shu’s Camber plates are mounted funny- he special ordered front knuckle brackets that have camber adjustment through the use of camber washers (same setup on some Super Racing coilover applications). That way, he can utilize the Mono Flex’s camber plates for caster adjustment. Clever guy.

Now leave your car alone, Shu. Your baby stroller, too.
