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

The S160 GS arrived from Toyota as a limousine pretending to be a sports saloon – a genuinely well-engineered FR platform, with a 2JZ-GE straight-six or 1UZ-FE V8 up front and a multi-link rear end that deserved better than the comfort-biased dampers it shipped with from the factory. Twenty-odd years on, those original springs and dampers have done their time; what remains is a solid rear-drive chassis that responds well to a considered suspension overhaul.

The XYZ Racing Street Advanced coilover kit is built directly for the GS 300/400 S160 and sits at the junction of daily usability and enthusiastic driving. Ride height adjustment lets you correct the stances those factory Lexus engineers always kept too conservative; 720-way damping adjustment gives you the range to tune for a weekday commute in the morning and a back-road blast at the weekend.

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

The S160’s double-wishbone front and multi-link rear geometry rewards predictable spring rates – firmer than stock, but not so stiff the car tramlines across imperfect British tarmac. With 720 damping settings accessible through the adjuster, you can run a softer setup for daily driving and step the compression up for a track day without touching the hardware. Bringing the GS 300/400’s ride height down reduces body roll through direction changes, keeps the camber curves in a more useful range, and addresses the tendency towards mild understeer the stock setup builds under corner load – a consequence of those heavy drivetrains sitting forward of the front axle.

About the Street Advanced coilover

XYZ Racing’s Street Advanced is the series the brand built its reputation on – developed over years by the company’s professional engineering team and refined through exposure to competitive events at circuits worldwide. It is positioned deliberately for road use and track day sessions, not as a competition-only setup that punishes you every time you hit a pothole on the way home. The 720-way damping adjustment is the headline number, and it is a genuinely broad range: enough to cover the gap between a relaxed motorway ride and a firm track configuration without needing to switch spring rates. Construction is designed to hold up under the thermal and mechanical cycling that comes from repeated use, and the adjustment range means the kit grows with a driver’s confidence rather than becoming a limitation.

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

This Street Advanced kit covers the S160-generation Lexus GS across both the GS 300 (2JZ-GE inline-six) and GS 400 (1UZ-FE V8) variants throughout the 1998-2005 production run. Confirm your chassis code is S160 before ordering – the preceding S140 generation and the later S190 use different suspension geometry and are not served by this kit.
