TEIN Street Advance Z Coilovers for Mini R56, Clubman R55 (07-14)

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.
