Tein Mono Flex coilovers

Monotube 16 way adjustable coilovers.

I personally installed and adjusted the ride hight and preload. These springs are no joke. If you really wanted to go race these they would be right at home. On the other hand there will be those drivers out there that will literally feel but hurt using these on the street because the spring rates are higher than most other kits. I've had these on since 2008, 60k miles later and im not feeling them loosen up like the stock dampers did around 50k. The dampers feel like they were valved for lower rate springs. In short when I take the dampers to there more loose ranges the suspension tends to flutter unless the ambient temps are about the 50s or lower. The colder these get the better they feel. If you live somewhere that has lots of potholes the kit will only put up with it for so long before the fluid gets to airated and then it doesn't matter what setting you select, the dampers just feel like there barely working at that point. Did I have fun with this kit... Yes! Is it! for everyone Noooo!

If your confident in your driving skills and your oneness with your roadster, the Mono Flex kit will give you loads more of the aforementioned.

Tein S-Tech springs

These are Green lowering springs, that will lower the car about an inch.

Well I installed these yesterday along with KYB AGX shocks. I must say that I'm very impressed, the look is perfect. My 15 inch Konig Heliums fill the wheel well perfectly now. Since 01+ seem to ride a bit high from the factory this was worth the cost just for that improvement in the look of the car. The spring rate is low enough not to hurt when you do encounter a large bump or pothole. These springs are a perfect match for the KYB AGX shocks. The handling has been a vast improvement. Body roll has decreased significantly, its not perfectly flat, but this is a street car, and I don't really expect that. Brake dive is almost gone under normal braking (I tend to be a heavy/late braker). The ride has actually improved, but if u do encounter a large pothole, is more noticeable. I think this may be attributed to the lower ride more than anything, but I'm not certain. I have no complaints w/ these springs thus far. I'm very impressed w/ the ride, look, and handling improvements this modification has made.

Again I installed these w/ KYB AGX shocks, a great combo that I would recommend to anyone who wants to drop their car about an inch, improve the handling and have no real adverse reaction on the ride (to me its an improvement).

Tein S springs and KYB shocks

[7/14/2006] Reviewed by: Michael George Stoukides - mstouks@mindspring.com

Applicable to: '90 - '97 1.8 liter

I have a 1996 Miata with 99,000 miles in which I have installed TeinS lowering Springs and KTB AGX 8 way adjustable shocks

this is my first time use of either product and have placed approximately 200 miles on the set up

After much research on Miata.net I decided on this particular configuration. The Tein s lower the car about an inch all the way around elimating the gap found on most NA. The ride is mostly stock with an added degree of firmness. The KYB are set at 5 in front and 4 in the rear. I live in New England known for crappy roads and no matter how hard I try have yet to bottom out. I firmly believe that this set up will give the Miata customer a marked degree of firmness and control and gives a really aggressive look to the Miata. My car is a dailey driver and a 365 day a year driving machine. Highly recommeded give your Miata alittle more Zoom Zoom.

Tein Flex coilovers, stock spring package.

Excellent. No problems in over 25k miles including daily driving in New England winters, terrible roads, and autocrossing on R compound tires.

Please search the Miata.net forum and also look at my Tein FAQ on my Cardomain Website (miata.cardomain/com/id/icehawk). In short one of the best dual-purpose systems out there. Highly recommended over mix & match setups like Koni + GC or similar. Pillowball mounts and adjustable shock lenght allow for signifigant lowering without loss of suspension travel. Wide range of damping offers a very good ride will still allowing you to FTD at a local autocross. Again, if you are interested please research in the forum as these are a very well known product!

TEIN Type Basic

[11/27/2005] Reviewed by: Justin Poole - supermiataman95@houston.rr.com

Applicable to: '90 - '97 1.8 liter

Basic coilover setup. Shocks and springs with adjustable ride height. No upper mounts included in this package.

I have had the product for a few months, and I love it. Upgrading to this from a stock setup was a night to day difference. the ride is better than my old shocks, but with a stiffer feel around sharp corners. I use these on my car that I drive occasionaly on the street and to get to and from AutoX events. They do good during AutoX as well as on the street.

Im would recommend these for street and mild competition driving, but for racing and competing to win in AutoX, you may need something more agressive.

Complete coilover set with pillowball upper mounts, adjustable spring perches and adjustable shock body length. Includes spanner wrenches and complete setup instructions. These coilovers will fit any year Miata, mine is a 99.

These coilovers will transform your car. I replaced the popular FM/KYB combo with these. The ride quality is now better than stock. Coupled with Superpro bushings, the car is incredibly responsive without any harshness whatsoever. Since the damping adjusters are on top (16 settings) changes are a snap at the track or when the mood strikes. With the adjustable shock body length, you can lower your car without sacrificing shock travel.

On the suggestion of Eddie at Adrenaline Racing, I set the spring preload to .5" and the ride height to 12.5" fender to wheel center front and rear. This height gives the car a nice stance while still allowing me to clear most speed bumps and driveways. I went with the 9kg/cm front springs in order to preserve a 1.5:1 ratio between spring rates. This is the same as the FM springs I had and I liked the balance. I haven't experimented much with the damper settings yet. So far, I like 10 all around (1=hard, 16=soft). I may change this to suit my preferred balance later. I can't imagine anyone not loving this upgrade!

Tein Flex

Tein Flex Full Coilover Adjustable Suspension with normal 7/6 spring rates

Excellent experience; highly recommended. After researching the forums for nearly a year, I spent the big money on this premium full coilover suspension, and am not disappointed. Got a good price and fast delivery through www.adrenalineracing.com.

I had the suspension installed according to Tein installation default recommnedations, with the exception that I had the shocks set at 12F/14R clicks from full hard (softer settings) instead of the 8/8. Handling and ride observations: 1. Tein says the car should be at around 12.72" F; 12.64" rear from hub center to fender. Ina actuallity, the height comes out at 12.0/12.25 on my 2000SE. The car does NOT look slammed or ricey in any way. I have no tire scrub, even under hard cornering. 2. The ride is actually smoother than stock at my 12/14 shock settings. 3. The ride is MUCH more controlled. Bumps, street cracks, and road reflectors no longer disturb the car. The old jumpy roadholding is gone. Now it's just smooth, solid, and controlled. Now rides like a heavier car, but handles like a lighter one. VERY nice indeed. 4. Along with Icehawk's alignment recommendations, the car now corners like it's on rails. I thought it handled nicely before, but boy was I wrong. 5. The car no longer bucks or dives under hard shifting, which equates to a MUCH more pleasurable driving experience. Now it just accelerates through the shifts with complete level and smooth ease. This is excellent for me since I am adding forced induction within the next couple of weeks. The stock suspension would have really stunk trying to handle even more power.

Tein HA Coilover Kit

[9/25/2003] Reviewed by: Steve Lewinski

Applicable to: '90 - '97 1.8 liter

Complete kit with shocks, springs, helper springs, boots, bumpstops, spanners. Threaded shock body for height adjustment, 16 damping settings via top knob. Spring rates Front: 280 lbs/in. Rear: 224 lbs/in. Other spring rates are available from Tein. Shock bodies can be factory rebuilt. Bodies are ~2mm shorter, throw ~5mm shorter. $850 eBay

Upper shock mount must be rounded out. Spring compressor needed only to retrieve bumpstops from the old shocks. I used stock bumpstops, cut from boot, modified for width and shaved ~.75cm in length. I didn't need the helper springs. Strangely, the front's lowest height setting is not as low as my old set up, but low enough (~1.25 in. below stock). Consider stock top mount modifications or aftermarket top mount kits (RSpeed dumper kit, Flyin Miata pillow ball mounts, Tein Pillow ball mounts, etc...) if you want the "slammed" look in front.

Purchased to replace an aging Eibach Pro Kit/Tokico Illumina combo. The Tokicos always felt as though they were mainly damping on compression and were not strong enough to damp the Eibach springs on rebound. The Teins have less compression and more rebound damping. The standard Tein spring rates are very good on my 96 miata. The ride is taut, yet smooth and far less busy. Gives larger car stability on the expressway without sacrificing manueverability when hotdogging it. There have been rumors of rusting on some HA kits. I doubt if they could rust any more than the Tokicos they replaced. Great deal for the daily driver/weekend autocrosser/sometime track enthusiast. Very happy with this product.

Tein S-Tech Springs

[8/4/2003] Reviewed by: Jason Loy - jason@jasonloy.com

Applicable to: '99 + 1.8 liter

Stiffer springs for the M2 Miata. Increases stiffness by about 46% over stock springs (rated at 235 front and 173 rear). Lowers the car about 1 inch.

First off - the price is fantastic. These are a good value in comparison to many other products on the market. Tein supplies about 60% of the Japanese suspension market, but is almost unheard of here in the states. Secondly - after installing them the car is noticably lower. No more wheel gap! The car looks much more aggressive and ready for action. Finally (and most important) - The handling is much improved. I had stock shocks and springs (not sport package). Dive in braking and squat in accelerating is all but gone. Body roll is much less pronounced. Combine these spings with some upgraded sways and I think there would be no body roll at all. The ride isn't overly harsh either. I used a new set of stock shocks, knowing that I will have to replace them soon. The roads here in New England can be pretty nasty but these springs seem to handle them pretty well without rattling teeth or causing kidney failure.

Go buy them! For about $140 they are a great value if you are looking to upgrade your suspension. I'd recommend putting new upgraded shocks on at the same time if you've got a higher milage car, but other than that, go for it!

Tein NA springs & shocks kit

[8/11/2001] Reviewed by: Jesse Lee - jesseclee@hotmail.com

Applicable to: '90 - '97

Tein NA kit w/ medium springs, purchased in groupbuy for $750 + customs/shipping ripoff. Bought from Boom Plus Toys of Canada.

Product: 16 clicks adjustable via top knob (combined, though mainly rebound damping. The front compression has a small adj. range. The rear has virtually fixed comp. damping) Height adjustable via 4 perch positions. Lowers the car 30,40,50,or 60mm in front; and 27,37,47,or 57mm rear. Springs are mildly progressive, not strongly progressive like the M2 NA set. Can use w/ other aftermarket springs. Rebuildable via factory. Extremely concise & well illustrated instructions in Japanese. Comes w/ their own bumpstops, which are a little shorter than stock (forgot to measure exactly) Case length is shorter than stock by a paltry 6 & 7mm f & r, while total extended length has been reduced 38.5 & 43.5mm! Resulting in tiny increase in compression stroke & substantial loss of rebound!

Install: straight forward except you need to open the D shaped hole in the stock upper-mount into a round hole. This is easily done w/ hand file. Need spring compressor to INSTALL spring. Performance: Whatever the stroke/travel numbers, in practice this NA kit rides very well. The height adjustment is great. The damping, which I left on 9, is excellent at virtually any speed. Perfectly matched spring/damping. I haven't tried any other settings yet, and feel absolutely no need to. Highly recommended fast street set-up.
