Product Description

The TEIN GSY20-81SS2 Street Basis Z Coilovers are an entry-level adjustable suspension kit designed for RWD Toyota Altezza and Lexus IS200/IS300 vehicles from the early 2000s. This coilover kit replaces the factory springs and dampers with height-adjustable units that let you tailor your vehicle's stance for a more aggressive look and improved handling compared to stock suspension.

Built with twin-tube dampers and fixed damping force, the Street Basis Z focuses on ride comfort and everyday usability while still providing a lowered stance. Threaded spring seats allow you to fine-tune ride height without complex adjustments, and the ZT-coated threaded sections enhance corrosion resistance for long-term use. The kit reuses OEM upper mounts for straightforward installation and includes all necessary hardware. These coilovers are ideal for drivers seeking improved handling and a lowered profile on street-driven classics like the Altezza and early Lexus IS models.
