Product Description

The TEIN Flex Z VSY20-C1SA3-C is a complete, ready-to-install coilover kit built specifically for the 2000-2005 Lexus IS300 (JCE10L), including the SportCross wagon. Unlike TEIN's Street Advance Z line, which asks you to reuse your factory upper mounts, the Flex Z ships as a true four-corner kit with brand-new reinforced rubber mounts included, so every part of the suspension going back into the car is fresh rather than a mix of new dampers on old hardware.

At the core of the kit is TEIN's Advance Needle damping system, giving 16 levels of adjustment through a single dial that tunes compression and rebound together - useful for owners who want to move between a comfortable daily setup and a firmer, track-oriented feel without swapping parts. The full-length ride height adjustment means you can set anything from a mild, factory-plus stance to an aggressive drop without changing the shock's usable stroke, and the twin-tube, Sealed Structure damper construction is built to hold that tuning over years of use.

This kit suits IS300 owners who want a genuine performance and stance upgrade in one purchase rather than piecing together separate springs, shocks, and mounts - a strong fit for street builds, weekend track days, or show cars where both ride quality and adjustability matter. EDFC compatibility also leaves the door open for adding electronic damping control down the road without replacing the coilovers themselves.
