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

The S160 GS arrived in 1998 as a luxury express: double wishbones up front, a multi-link rear, and Lexus damping calibrated firmly around motorway compliance rather than lateral composure. In GS 300 trim that platform carries a 2JZ-GE inline-six that enthusiasts have been modifying since the late nineties; the GS 400 installs a 1UZ-FE V8 instead, which pushes additional weight over the nose and compounds the front-biased handling balance owners notice first when they start driving with intent.

The XYZ Racing Super Sport coilover kit for the Lexus GS 300/400 S160 works against those factory tendencies – reducing nose-dive under braking, cutting body roll through quick direction changes, and lowering the centre of gravity to something closer to what the car’s sporting pretensions actually call for.

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

The S160’s front double-wishbone geometry rewards a matched increase in spring rate and damping firmness that the OEM single-rate setup never fully exploits. Thirty-six damping positions give you the range to run a softer map for urban miles and step up noticeably for a circuit sprint without touching any hardware. The GS 300’s front weight bias, more pronounced still in GS 400 guise with the V8 over the nose, benefits directly from a stiffer front end that keeps geometry consistent through extended braking zones. Reduced body roll improves tyre contact consistency through fast, open corners – the kind the S160 finds on a decent back road at pace. Ride height adjustment is independent of spring preload, so correcting stance doesn’t automatically alter the damping work you’ve already done.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road and weekend-track specification – broad enough in its calibration range to cover daily use without asking for a dedicated second setup for circuit days. Damper adjustment runs to 36 positions, a genuine working spread from compliant urban behaviour to flatter, more committed corner response; the vendor specifically developed this adjustment range to address the harshness typical of stiffer spring rates on imperfect road surfaces. Ride height adjusts on the threaded collar independently of spring preload, so stance corrections and damping calibration can be done in sequence rather than as a single trade-off. The Super Sport is validated for both daily driving and weekend race use – a scope that maps directly onto how most S160 GS owners actually use the car.

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

This kit is built for the second-generation Lexus GS platform, chassis code S160, across both the GS 300 inline-six and GS 400 V8 variants produced from 1998 to 2005. Confirm your chassis code is S160 and verify your specific model year before ordering – the GS range spans two clear generations and parts catalogues occasionally conflate them.
