If you’ve spent a decent amount of time looking into the best coilover brands on the market then you’ve probably come across a little name called TEIN (standing for “Technology” and “Innovation”). TEIN’s suspension products are popular all over the world and are used in a wide variety of vehicles for different styles of driving.
But if you’ve never used a TEIN product before then you may have a lot of questions about their performance and quality, as well as how they are impacted by their relatively low prices. Below we’ll tell you about TEIN’s manufacturing and why you shouldn’t be concerned about their value, as well as an overview on three of TEIN’s best coilover kits.
TEIN: Performance Vs. Pricing
A lot of people like to assume what the quality of a product is based on its price. While this can be a useful rule of thumb for some things in life, it is by no means a foolproof system. TEIN’s coilover suspension kits, such as the TEIN Basis coilovers or the TEIN Superstreet coilovers, are just some of the many exceptions to the rule.
TEIN builds all of their products with a high degree of quality. This is apparently true whether the kit costs $400 or $4000. All of their coilovers are rigorously tested in a variety of conditions which includes different cars and different roads.
As a result, TEIN has been able to produce many coilover kits with diverse applications because of their R&D style. This means that no matter what your budget is, you’ll be able to find a TEIN kit that fits your needs, whether it be the TEIN Flex Z coilover or the TEIN Basis coilovers.
Another important fact about TEIN is that their manufacturing occurs in-house at their HQ in Japan. While they do have a factory in China to keep up with demand, TEIN’s philosophy quality control standards and in-depth testing hasn’t changed a bit as far as we can see.
TEIN originally only had a handful of products, but as they’ve become one of the most trusted suspension device manufacturers in the world they have expanded their lineup drastically. Let’s take a look at three of their coilover kits to really hammer home just what these babies can do.
TEIN Street Basis Coilover Kit
The TEIN Street Basis Coilover kit can be considered TEIN’s flagship product. It is the redesigned version of their original TEIN Basis Coilover kit that helped them become the giants they are today.
While these aren’t the cheapest products that they sell, they are still on the low-end when it comes to pricing. They are not only very durable but are specifically designed to allow for both a smooth and easygoing riding experience as well as enduring more aggressive and sporty driving styles.
The Street Basis Coilover kit’s actual physical attributes are impressively well-thought out. This version features a greater piston diameter for both rear and front struts measuring at about 22mm. This creates superior control and handling. The damper body of the coilover is coated with external powders that improve both the lifespan and the durability of the overall unit.
All in all, there’s no doubt that a lot of thought went into this suspension kit despite the relatively low price. And that is why the TEIN Street Basis Coilover kit is as reliable and dependable as you’ve heard.
TEIN Super Street Coilover Kit
One of the most popular models in a more expensive pricing range is the TEIN Super Street Coilover. This kit uses a twin tube internal steel construction design and is coated with powder for durability and zinc for endurance and protection.
As the name implies, the TEIN Super Street Coilover is designed with the racing track in mind, but that shouldn’t repel you if you only stick to the road. This is one of TEIN’s high-end models, and like many of their suspension products, it works great on a variety of road conditions.
This model is made using four springs and four shock absorbers. Together, this makeup delivers an extremely smooth ride that delivers not only superior handling but great comfort as well.
The TEIN Super Street Coilover is also highly adjustable. Not only is ride height adjustable thanks to the spring seat but the Super Street also has 16-way adjustable compression dampers and rebound dampers.
While all of this may sound a little complicated to some, installing the TEIN Super Street Coilover is actually rather easy. The Super Street comes with upper mounts that are specifically engineered for a variety of car models. No matter what you drive, or how you drive, the TEIN Super Street Coilover should deliver the quality you want.
TEIN Flex Z Coilover Kit
The last suspension kit to discuss is the TEIN Flex Z Coilovers. These are one of the most popular models made and sold by TEIN.
The Flex Z is often noted for how smooth of a ride it provides which can be attributed to its height adjustment system. The height can be changed without impacting the spring pre-load or the damper stroke length. As a result, you can get a very easygoing driving experience, even during sharper turns. These are a great choice if you want to avoid over-steering or under-steering.
In typical TEIN fashion, the TEIN Flex Z Coilovers come with a 16-way adjustable damping force system and with four shock absorbers and four springs. They’re very durable, have a great lifespan and will provide a great ride quality no matter how you adjust the height. They’re even designed with no-sag springs made out of very high tensile steel that can be used reliably even in harsh winter conditions.
