The TEIN Street Basis Z Coilover Kit combines affordability and comfort in a masterfully engineered suspension system designed for daily driving enthusiasts. This ride height adjustable coilover kit delivers improved handling performance without compromising everyday comfort, making it the perfect upgrade for drivers seeking both style and substance.

Twin-Tube Design for Superior Comfort:

Unlike traditional mono-tube systems, the Street Basis Z utilizes an advanced twin-tube construction that achieves longer stroke with reduced repulsive force, resulting in exceptional ride comfort. This design allows you to navigate rough roads smoothly while maintaining stability at high speeds and comfort at low speeds.

Key Features:

• Thread-type ride height adjustment via lower spring seat positioning
• ZT Coating surface treatment on adjustment threads for abrasion and corrosion resistance
• High-performance damper oil that maintains stable viscosity across broad temperature ranges
• TEIN-green powder coating with patented 2-Layer, 1-Bake rust-proofing method
• Damping force adjustment dial for customizable ride comfort and handling
• Compatible with EDFC Series for driver-seat damping adjustment (vehicle-specific)
• Shortened shell case design for optimum damper stroke at lowered heights
• Factory-matched spring rates and damper valving eliminate guesswork

Technical Specifications:

• Spring Rate - Front: 5.0K (250mm)
• Spring Rate - Rear: 4.0K (257mm)
• Uses OEM upper mounts (not included)
• Simple structure for ease of installation and maintenance
