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

The S160 GS was never built for competition, yet its rear-wheel-drive layout, long-wheelbase platform, and choice of 2JZ-GE inline-six or 1UZ-FE V8 make it a serious tool on closed tarmac stages. Running one in a sealed-stage event means subjecting a full-size luxury saloon – and close to 1,600 kg of it – to compressions, crests, and patched road surfaces that will expose road-spec damping within the first few kilometres.

The XYZ Racing Tarmac Rally coilover for the Lexus GS 300/400 (S160) addresses that environment directly. The calibration is drawn from XYZ’s own tarmac rally programme, not repurposed from a road performance kit – and the difference shows most clearly when the surface deteriorates rather than when it’s at its best.

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

A road coilover handles surface imperfections individually. The Tarmac Rally specification is calibrated to manage sequences of them without allowing the chassis to step sideways – which matters considerably in a rear-wheel-drive car where the balance you’re relying on for rotation and throttle control needs to remain consistent. Suppressed body movement keeps tyre contact predictable through compressions, so the platform’s mass works with the suspension rather than against it when you strike a sharp bump at speed. That stability feeds directly into how confidently the 2JZ or V8 can put power down through patchy tarmac surfaces.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally line is derived from competition development on sealed stages, and the damper settings reflect that origin: the primary engineering brief is absorbing sudden, high-load impacts from uneven pavement without translating that energy into body pitch or bounce. On a platform with the S160’s weight, controlling rebound after a large bump is as important as the initial absorption – uncontrolled rebound lifts the tyre from the surface and reduces traction at precisely the moment you need it most. The construction addresses this by suppressing body movement sharply enough to maintain tyre contact through the compression and return cycle, keeping vehicle stability intact across consecutive surface changes. Every setting in the kit reflects what XYZ’s tarmac rally experience has shown works on a closed-stage surface, rather than what works on a smooth performance road.

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

This kit covers the Lexus GS S160 platform across the full 1998-2005 production run, encompassing both the GS 300 (2JZ-GE) and GS 400 (1UZ-FE V8) variants. The S160 chassis code distinguishes this second-generation GS from the earlier Z30 and the later S190 – confirm your build year before ordering to ensure the correct suspension mounting specification.
