TEIN Street Advance Z Coilovers for Mazda Miata/MX-5 (90-05)
The Street Advance Z damper is the evolution of the popular Super Street coilover. Developed to provide a sporty ride and aggressive stance, along with 16-stage damping force adjustment using Tein's new Advance Needle technology. This gives the driver the ability to fine tune damping force change. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Vehicle ride height is adjustable via the ZT coated threaded sleeve and spring seats. Updated internal components and external coatings increase durability and product life. Street Advance Z dampers are great for daily and spirited use, for all types of drivers.

Making an Incredibly Low Price a Reality
About the Sealed Structure
The top end of the shell pipe is narrowed, oil and gas are injected, and the whole unit is sealed by crimping the metal.
This new approach massively shortens the production process. As a result, we have succeeded in vastly cutting production cost.
Partial Production Process of STREET ADVANCE Z and STREET BASIS Z
Thread Type Ride Height Adjustment
The ride height can be adjusted by moving the lower spring seat up or down. Characteristic of this system are its simple structure and ease of use.
Twin-Tube A System
Compared to the regular mono-tube system, twin-tube attains longer stroke with a smaller repulsive force, resulting in high ride comfort.
Roads may have all sorts of surface conditions. This calls for shock absorbers with ample stroke, that operate smoothly. Thanks to this unique characteristic, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.
Uses OE Mounts
STREET ADVANCE Z and STREET BASIS Z use the vehicle's original upper mounts (not included in our product kit).
High Durability & Reliability
Optimal Dust Boot
Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber. (Some vehicles use their OE dust boots)
No-Sag Spring
Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2), our springs are outstandingly sag-proof and boast extreme resiliency. Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. Our high-quality springs can be used without worries, in any conditions.
High-Performance Damper Oil
Since TEIN's damper oil maintains a stable viscosity in a broad temperature range, it sustains smooth stroke and reliable damping force in a variety of circumstances.
Due to excellent anti-foaming properties, it's resistant to cavitation (bubble forming). Since it withstands high heat too, it's suitable for intense sport driving as well.
Furthermore, the damper oil keeps up its superior performance long-term, because it's resistant to deterioration over time.
Only STREET ADVANCE Z
Damping Force Adjustment
Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.
The above are examples, actual settings vary according to the vehicle's circumstances.
