XYZ Racing Street Advanced Coilovers — Lexus LS 400 (XF10) 1989-1994

The XF10 LS 400 arrived in 1989 with suspension so composed it made European luxury engineers pay attention. Three and a half decades later, those original dampers are well past their service life – and the enthusiast keeping an XF10 on the road in 2026 wants more than a like-for-like replacement. The XYZ Racing Street Advanced coilover for the Lexus LS 400 (XF10) gives the first-generation LS a setup that suits how the car actually gets used now.

This is the right specification for a GT car of this weight and character. The Street Advanced sits in the gap between factory-soft isolation and track-ready firmness – exactly where most XF10 owners actually drive: spirited fast-road use with the occasional open-day appearance.

What this coilover does for your 1989-1994 Lexus LS 400 (XF10)

The XF10’s four-corner double-wishbone geometry is more capable than the factory calibration suggests. Toyota spent heavily on the platform’s dynamic foundations, then tuned the springs and dampers firmly toward isolation. Running the Street Advanced brings that geometry into play properly: body roll tightens, the front axle loads more predictably under trail-braking, and the 1UZ-FE’s substantial engine mass sits lower in the chassis. At 720 damping positions you have genuine granularity – soft enough at low settings to preserve the long-distance composure that defines the XF10 ownership experience, firm enough mid-range to recover the body control the standard suspension trades away. Independent ride-height adjustment means a modest drop without forcing the spring rate up to compensate.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely specified coilover series and the product that forms the core of their road-going catalogue. Development ran over several years with the XYZ professional team, the series refined in parallel with testing at professional race events worldwide – which explains the calibration depth on what is otherwise a daily-usable product. The defining specification is 720 discrete damping positions, a level of adjustment granularity that most coilovers in this class do not approach. The series covers everyday road use and track days, with the damping range wide enough to support both without a full rebuild or separate spring setup between sessions. Drivers chasing pace and control in equal measure are the intended audience.
