XYZ Racing Racing Spec Coilovers — Lexus GS 300/400 (S160) 1998-2005

The S160 GS 300/400’s rear-wheel drive layout and considerable kerb weight create a handling envelope that the Lexus factory calibration never intended to explore at race pace. The inline-six in a GS 300 sits well forward in the engine bay; the V8 in the GS 400 adds further mass to that same front axle – both variants arrive at a circuit carrying a natural understeer tendency that demands proper suspension work before the balance can be usefully adjusted.

The Racing Spec coilover from XYZ Racing is the answer for S160 owners with genuine circuit intent. Settings for this application come from direct involvement in WTCC competition – not road testing, not theoretical modelling – and the specification reflects sustained circuit loading from the start rather than being dialled back for road-use comfort.

What this coilover does for your 1998-2005 Lexus GS 300/400 (S160)

On an S160, the clearest gains arrive under braking and through the transition from mid-corner to exit. The factory passive dampers allow significant pitch and squat under the deceleration and acceleration loads a live circuit produces, blurring the chassis feedback that makes confident late braking achievable. Replacing them with Racing Spec units – tuned to WTCC-derived settings – tightens the platform considerably. For S160 owners who have already addressed power, tyres, and braking, this is often where the GS’s latent dynamic ability becomes accessible rather than frustratingly out of reach.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s dedicated competition coilover series, built specifically for track and time-attack applications rather than the fast-road brief covered by other types in the range. Calibration data for each application comes from direct participation in WTCC events, meaning the settings reflect the actual demands of circuit racing rather than a simulated track environment. For S160 owners running heavily upgraded cars – aggressively modified engines, revised geometry, significant chassis preparation – XYZ Racing can produce custom shock absorbers built to that exact specification. Supply detailed information on every upgraded component fitted to the car plus the circuit or series you intend to run, and the damper unit can be constructed to match that precise configuration. This is a meaningful capability for GS 300/400 builds that have moved well beyond stock hardware.

Fitment for the Lexus GS 300/400 (S160) (1998-2005)

This kit is designed for the Lexus GS S160 chassis, covering both GS 300 and GS 400 variants produced between 1998 and 2005. Verify your chassis code is S160 before ordering – this generation sits on a distinct platform from the earlier S140 and is architecturally separate from the fourth-generation S190 that replaced it from 2005.
