TEIN GSTG4-8UAS2 Street Basis Z Coilover Kit

The TEIN Street Basis Z Coilover System combines affordability and comfort packaged into a masterfully constructed suspension system designed for daily driving and spirited street use. The Street Basis damper is the evolution of the popular BASIC coilover, offering enhanced performance and durability at an accessible price point.

Advanced Twin-Tube Design:

These coilovers utilize a Twin-Tube setup that when compared to the regular mono-tube systems, these twin-tube systems attain longer stroke with a smaller repulsive force, resulting in increased ride comfort. 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 speeds.

Key Features:

• Steel construction with twin tube internal design
• Larger 22mm piston diameter for strut type front and rear
• Thread-type ride height adjustment via moving the lower spring seat up or down with simple structure and ease of use
• Vehicle ride height is adjustable via the ZT coated threaded sleeve
• Powder coated damper body with non-welded ZT coated adjustment tube
• Full-length dust boots and 1-piece aluminum spring seat with delrin thrust washer
• Cold formed with SAE9254 steel springs (minimum tensile strength 200 kgf/mm2) that are outstandingly sag-proof and boast extreme resiliency
• Uses factory original upper mounts (not included)

Superior Durability:

TEIN's damper oil maintains a stable viscosity in a broad temperature range, sustaining smooth stroke and reliable damping force in a variety of circumstances. 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. TEIN's unique ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance.

Updated internal components and external coatings increase durability and product life. Street Basis dampers are great for daily driving and spirited driving for all types of drivers. Made in Japan under strict quality control standards and developed by highly trained suspension engineers.

Includes 1-year Manufacturer's Defect and Sag Warranty covering over 5mm sag, breakage, deformity, and noise. Does not cover powder coat finish and rusting.
