XYZ Racing Street Advanced Coilovers — Lexus GS 300/400 (S140) 1993-1997

The S140 GS arrived as Lexus’s first genuine attempt at a driver’s saloon – rear-wheel drive, a 2JZ straight-six or 1UZ V8, and a chassis that looked promising on paper. What it had was suspension calibrated firmly for motorway comfort: body roll crept in earlier than the platform deserved, turn-in was vague, and the GS 400’s heavier V8 nose exaggerated the front-end wash in tighter corners. Thirty years on, the cars that have survived into enthusiast ownership are rarely on the standard setup, and sourcing sensible upgrade paths for the S140 gets harder each year.

The XYZ Racing Street Advanced coilover for the Lexus GS 300/400 addresses that specific gap: a coilover designed for the car to be driven on real roads, with enough adjustment range to stay useful through different conditions and load states.

What this coilover does for your 1993-1997 Lexus GS 300/400 (S140)

Fitting the Street Advanced draws in the S140’s factory ride height and sharpens the link between steering input and chassis response. The body float the Lexus was built with – comfortable on a long run, frustrating when the road narrows – becomes controllable. Adjustable ride height lets owners set the car where the arches actually look right, rather than living with the nose-high standard stance. The 720-way damping adjustment is the defining specification here: on a car that scales at roughly 1,700 kg depending on powertrain, a wide working damper range matters far more than spring rate headlines alone. Compliant enough for a Monday commute, firm enough when Saturday demands it.

About the Street Advanced coilover

XYZ’s Street Advanced sits at the top of their road-biased range – a coilover built for the driver who uses the car daily but holds a track day date in the calendar. Development has drawn on testing in professional motorsport environments over a number of years, with those findings feeding back into the production valving and construction specification. The 720 damping adjustment settings cover a band wide enough to shift the car’s character meaningfully depending on condition or use, far beyond the crude comfort-and-sport toggle of lesser units. Construction and spring rates are calibrated with normal road use as the primary brief, with circuit capability as a secondary design requirement – a different priority order to a pure track coilover, and the right one for a GS 300 or GS 400 that spends most of its life on public roads.

Confirm your chassis code is S140 before ordering – the later GS generations used different platform codes and fall outside this fitment.
