XYZ Racing Circuit Master Coilovers — Lexus GS 200t/250/350 (L10) 2012-2026

The L10-generation GS arrived with genuine rear-wheel drive credentials – proper FR layout, a 3.5-litre V6 in 350 specification, and an optional adaptive suspension system on F Sport variants that told you Lexus knew the platform could reward set-up work. What it also arrived with was a damping calibration aimed squarely at motorway refinement rather than the kind of sustained lateral loading a circuit session asks of it.

The Circuit Master addresses that gap directly. This is XYZ Racing’s competition-oriented coilover – the same line that extends to Racing Spec, Drift Spec, and Tarmac Rally variants and is tested through XYZ teams on international circuits – brought to the GS 200t, 250, and 350 for drivers moving this platform into track-day or club-sport use.

What this coilover does for your 2012-2026 Lexus GS 200t/250/350 (L10)

Install the Circuit Master on the L10 chassis and the GS’s handling balance shifts immediately. The factory front-end float that appears under sustained cornering loads tightens up; with rebound tuned correctly for the car’s kerb weight, turn-in sharpens and mid-corner composure improves without sacrificing the controlled ride needed to use kerbs productively.

The 9,720-adjustment range across three separate knobs – bump, rebound, and the third governing high-load oil passage – gives the kind of resolution that matters on a car of this weight. The GS 350’s V6 generates torque loads through the rear axle that vary considerably between corner entry and mid-corner power application; independent bump and rebound control means you can stabilise the rear under acceleration without deadening front compliance. Ride height adjustment through the coilover collar lets you address the GS’s factory rake independently of spring rate.

About the Circuit Master Coilover

The Circuit Master sits at the top of XYZ Racing’s coilover hierarchy, sharing its architecture with the Racing Spec, Drift Spec, and Tarmac Rally variants used by XYZ teams at competitive events on circuits worldwide. The defining feature is a three-knob system covering bump, rebound, and a third adjuster working through a small-passage oil-flow design built for high-load cycling. The 9,720 possible adjustment states that result represent a range far wider than conventional single-adjuster dampers allow, making it possible to configure the unit across everything from a controlled club-sport set-up to full competition trim. One characteristic worth noting: the small-orifice oil path is deliberate for circuit use, and may produce a brief audible note when the damper cycles hard over a sharp surface transition – expected behaviour on a unit calibrated for smooth track surfaces rather than broken road.

Fitment for the Lexus GS 200t/250/350 (L10) (2012-2026)

This kit covers the L10-generation Lexus GS across its full production span on the 200t, 250, and 350 powertrains, chassis code L10, from 2012 to 2026. All three engine variants on the rear-wheel drive platform are covered. If your GS is an F Sport model equipped with Lexus’s adaptive variable suspension system, confirm standard coilover fitment compatibility before ordering.
