TEIN Street Basis Z Coilover Kit – Nissan 350Z (Z33) TEIN

TEIN Street Basis Damper is the evolution of the popular BASIC coilover model. It incorporates new internal and external components, newly developed coatings and new manufacturing processes.

TEIN engineers have spent many hours developing new seals and internal components to improve durability and product life. This was one of our major goals for the new model.

Newly developed coating for improved durability and hassle-free ride height adjustment. TEIN developed this coating in-house after stringent test and analysis procedures. Our engineers tested different coats, application methods, cleaning processes, etc in our own brine salt water testing machine which simulates heavy solvents/ road salts used in cold weather climates.

Slip-fit threaded adjustment tube. Allows for damper body and threaded sleeve to be thoroughly coated for rust/ corrosion protection. The slip-fit allows a more thorough coating on the threaded section as well as powder coated damper body.

Revised Aluminum Spring Seat and Delrin Thrust Washer are light weight and durable. This combination allows for smooth ride height adjustment. The new spring seats have a larger contact surface area and eliminate the need for a rubber spring seat.

 

Features

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 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 BASIS Z use the vehicle’s original upper mounts (not included in TEIN product kit).

High Durability and Reliability

• 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.

Rust-Proofing

• A bright TEIN-green powder paint is used on the shock absorber’s shell case. Our powder coating technique produces an extremely strong and durable barrier. No harmful organic solvents are used, for minimal pollution.
• Superior durability and corrosion resistance are achieved by TEIN’s patented 2-Layer, 1-Bake powder coating method, which uses 2 layers of anti-rust paint on a blasted surface. (Japanese patent number 4347712)

Special Surface Treatment ‘ZT Coating’

• Our unique ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance.

• With zero claims for stuck parts due to rust in 500,000 shock absorbers, TEIN shock absorbers are amazingly rustproof. We’re confident of customer satisfaction even in coastal areas or regions with heavy snowfall.
