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

The S160 GS left the factory tuned for hushed motorway comfort, which means a soft spring and damper package that lets a near-1700kg saloon roll, dive and float the moment you start driving it with intent. XYZ Racing’s coilover range for the Lexus GS 300/400 (S160) 1998-2005 swaps that compliance for height-adjustable, damping-adjustable struts that bring the body back under control without making the car brittle on a broken B-road.

With the 2JZ-GE straight-six of the GS 300 or the 1UZ-FE V8 of the GS 400 sitting well forward in the chassis, the nose dictates how these cars behave. Drop the ride height, firm the damping and the front end tightens, turn-in sharpens, and the rear multi-link is freed to follow cleanly. That transformation is a large part of why owners keep building the S160 as a rear-drive project car in 2026.

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

Lowering the GS on adjustable platforms pulls the centre of gravity down and kills the factory wallow, so the car sits flat through a fast sweeper instead of leaning onto its outside shoulder. The damping adjustment lets you firm things up for a spirited weekend run and wind it back for the commute, so the saloon stays usable every day. On the GS 400 in particular, the extra V8 mass over the front axle makes brake dive obvious on standard struts; firmer valving keeps the nose settled under heavy stops and steadies the platform for the next corner. You also get the stance most S160 owners are after, set precisely with the threaded lower mounts rather than guessed at with springs alone.

About the XYZ Racing coilover range

Each kit pairs height-adjustable bodies with independently adjustable damping, so ride height and ride quality are tuned separately rather than locked together as they are on a fixed lowering spring. The range spans nine specifications for this chassis, from Street Advanced and Super Sport for fast-road use, through Top Sport, Circuit Master and Racing Spec for circuit and track-day work, to Drift Spec for sideways duty and Tarmac, Gravel and Pro Rally builds for stage use. That spread means the same well-supported GS platform can be set up as a comfortable lowered cruiser or a stiff, low track tool depending on which spec you configure. The hardware is built for repeated adjustment, so the setup you choose on day one can be refined as you learn the car.
