MTS
All coilovers come with springs made by Eibach and offer height adjustment, but they do not have hardness settings. Generally, these suspensions are a softer option compared to higher-end coilovers. Depending on the car and if it allows, they can be ordered with camber plates.
It is important to note that all components can be easily purchased separately – from springs and nuts to complete shocks, if needed. The suspensions are available in two coatings – Gold and INOX. In the Gold version, the shocks are galvanized against rust, while the INOX coating provides significantly greater durability, similar to the shocks found in KW coilovers. However, the price of INOX is about 30% higher compared to the Gold version.

- Street
- Stance
Use:
We highly recommend MTS for Daily Driver cars, as we have received many positive reviews regarding ride quality and durability for everyday driving. We still don't have feedback on how it performs during more serious track driving.Tein
The most well-known Japanese suspension with a distinctive green color, tested over the years worldwide and guaranteeing its quality.
- Tein Basis Z – the most basic version of Tein. They offer height adjustment and that's it – with the softest springs providing comfort for daily use. The shocks have a separate thread, making their replacement easier in case of an issue. No frills, but no compromises either. This is equivalent to MTS, but the price is about 30% higher than their basic model. At the same time, the price of Basis Z is about 30% lower than that of KW V1. This is the best choice for everyday use, but it's not optimal for track use.
- Tein Advance Z – practically the same as Basis Z, but with firmer springs and 16 levels of hardness adjustment. It includes everything good from Basis Z with improved features as an addition. Its price is about 20% higher, but this is fully justified. Compared to the equivalent KW V2, its price is about 30% lower. This suspension is perfect for everyday use, and we would recommend it for some track days, but it is still not optimal for a car that is meant exclusively for the track.
- Tein Flex Z – the first high-end suspension from Tein, manufactured in their factory in Japan. Compared to Advance Z and Basis Z, Flex is designed to withstand anything, with a significantly better overall construction, without making any compromises. All models come with metal hats, and there is no need to disassemble the stock shocks of the car for installation. If the car allows, the suspension can be ordered with camber plates. Flex Z features 16 levels of hardness adjustment. However, compared to the direct equivalent, the BC-BR series, Tein offers a softer setup.
Use:
Tein offers an overall softer setup, making it ideal for daily use. The softest setting is almost identical to the stock suspension, while the firmest setting is more than sufficient for track and more serious driving. We receive a lot of positive feedback for this suspension, with mentions that it withstands years of intense use in various conditions (track, daily driving, winter driving) without any issues.
BC Racing
BC Racing is a world-renowned brand. If there is no suspension for your car, you're probably riding a bicycle.
All suspensions come with height adjustment, spring, hardness, and camber plates, if the car allows. Compared to Yellowspeed and Tein, BC is the stiffest suspension, which is an advantage for serious driving, but it cannot be softened to the level of the other brands for daily comfort.
At the moment, we have relatively few reviews from customers and acquaintances, and the opinions on durability are not very positive – it typically lasts about 2-3 years.

YellowSpeed
The suspension that not everyone has heard of, but is the best in terms of price, comfort, features, and spare parts.
All suspensions come with height adjustment, spring, hardness, and camber plates, if the car supports it. For some cars, there are even options for separate spring and shock absorbers or coilovers.The biggest advantages are that new springs for setup changes or spare parts can be ordered very quickly, easily, and affordably.
Yellowspeed also offers 2 higher classes for track use and a 3-way motorsport grade class, but the standard setup will be more than ideal for everyone.
Use:
In Bulgaria, it is widely used for daily driving and occasional track use several times a year.
Silvers
The suspension that is a higher class than BC Racing, with the same features, but no one has heard of it, even though it has been produced since 1999.
IT COMES WITH A LIFETIME WARRANTY FOR THE SHOCKS.
D2
A suspension that many people have heard of, but never actually purchased.
Like all coilovers, they have height adjustment and spring adjustment. All come with camber plates in case the car supports them.
Use:
D2 is a performance suspension, primarily used by cars designed for track driving.
KW
If KW makes suspension for your car, they have designed it to work perfectly both on the street and on the track.
Most suspensions come without camper plates, but for cars that support them, they can be ordered separately. This allows for even greater flexibility in suspension settings, while also providing better grip and stability. Additionally, the suspension offers comfortable ride compared to all other options, making it suitable for both daily driving and more intense use. The innovative inox coating provides significantly better rust protection compared to all other options, ensuring durability and longevity of the suspension.
In addition, the nuts are locked with a small hexagon, which prevents them from seizing and ensures the security of the construction. This is one of the reasons why we receive only positive feedback about the suspension. We even know of several sets that have been used for more than 10 years without any issues with the shocks. For even greater peace of mind, we offer a verified 2-year warranty if the suspension is installed with us. All suspension parts can be ordered separately, and if necessary, the shocks can be recycled directly by KW, which adds extra value and convenience for customers.
Series:
- KW V1 - the most basic, yet the best for everyday use. The suspension comes with height adjustment on the spring, providing convenience in tuning. This series offers the best balance for the car without the need for additional adjustments, making it extremely comfortable for daily driving. It offers enough stability for track use, although for some cars, it may be a bit softer than optimal. However, this can easily be corrected by adding aftermarket sway bars, which will improve stability during aggressive driving.
- KW V2 – Street + Track – The perfect suspension for a weekend car that will also be used on the track. The suspension offers height adjustment on the spring, providing the necessary flexibility for personalizing the ride. The hardness adjustment is extremely precise, with every click being noticeable not only in ride comfort but also in the car's handling, allowing for optimization of stability and dynamics. This suspension is ideal for both daily use and serious track sessions, offering a perfect balance between comfort and performance.
- KW V3 - The suspension you won’t replace with another. In practice, V3 is similar to V2, but offers additional individual control for compression and rebound, providing even more precise tuning of the suspension. This allows the user to adjust the shocks in two main directions, achieving an optimal balance between comfort and performance. Furthermore, V3 offers Coilover setup options for cars that have separate springs and shocks on the rear axle, providing even greater flexibility and the ability to adjust the suspension according to the specific requirements of the vehicle.
