Product Description

The TEIN GSY20-91SS2 Street Advance Z Coilovers are a multi-vehicle adjustable suspension kit engineered for a range of rear-wheel-drive Japanese sedans and wagons, including Toyota Altezza, Lexus IS200, Lexus IS300 (including SportCross), Toyota Mark II, Mark II Blit, and Verossa from the late 1990s through the mid-2000s. These coilovers replace factory shocks and springs, giving drivers the ability to tune both ride height and damping force to strike a balance between everyday comfort and engaging handling.

Featuring 16-way adjustable damping, corrosion-resistant ZT-coated threaded adjusters, and twin-tube damper construction, this kit enhances stability and cornering response without overly harsh ride quality. Ride height can be lowered significantly relative to stock using the threaded spring seats, and the included hardware provides everything needed for a complete installation aside from optional TEIN EDFC electronic damping control. Whether you're improving stance, tuning handling, or optimizing the feel of your classic Toyota or Lexus RWD sedan, the Street Advance Z offers a durable, customizable suspension solution.
