XYZ Racing Circuit Master Coilovers — Lexus LC500 (URZ100) (Cancellation Kit for Electronic Damping) 2018-2026

The LC500’s factory Adaptive Variable Suspension is tuned for GT comfort, not for holding a line lap after lap at Silverstone or Anglesey, and its electronic dampers actively fight any static coilover you bolt underneath them unless the AVS control signal is dealt with first. The Circuit Master kit for the URZ100 is built specifically around that problem: full mechanical damping control paired with a cancellation kit that satisfies the LC500’s electronics so the dash stays clean and the car drives as intended.

This is XYZ Racing’s circuit-focused range, aimed at sustained lap-time work rather than a single fast road blast. On a 2+2 GT coupe carrying real weight over the front axle, that means dialling out the nose-heavy understeer the LC500 shows under trail-braking into a hairpin, and giving the rear end a firmer, more predictable platform to rotate against once you’re back on the throttle.

What this coilover does for your 2018-2026 Lexus LC500

With 9720 individual damping combinations on tap through the kit’s 3 adjustment knobs, you can set compression and rebound independently front and rear rather than accepting one compromise setting for the whole car. That range lets you firm up the front to cut the dive and push that shows up under hard braking into slower corners, while keeping enough rear compliance to stop the LC500’s mass stepping out over kerbs and mid-corner bumps. Ride height becomes fully adjustable too, so you can drop the centre of gravity for track days and still raise it back for the drive home. Because the cancellation kit removes the factory AVS conflict, every one of those 9720 settings is actually usable – nothing in the dash is fighting the new dampers behind the scenes.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, developed and run by XYZ’s own racing teams across circuits internationally rather than built purely as a road product first. The 3-knob adjustment architecture is what gets you to 9720 possible combinations, letting front and rear compression and rebound be tuned independently for a given circuit or driving style rather than moved together as a single dial. The knobs work through a small oil-hole passage design; over bigger bumps or kerbs that can produce a faint noise from oil moving through that passage, which is a normal characteristic of this construction rather than a fault, and the kit is built with circuit surfaces – not rough B-roads – as the primary use case. For the LC500 specifically, the cancellation kit is fitted alongside the coilover hardware so the electronic damping cancellation is sorted at installation rather than left as an aftermarket workaround.

Fitment for the Lexus LC500 (2018-2026)

This kit is built for the LC500 URZ100 chassis across the full 2018-2026 production run, and includes the cancellation kit required specifically for cars fitted with the factory electronic damping system. Confirm your car is the URZ100-generation LC500 before ordering, since the electronic cancellation hardware is matched to this chassis’s AVS wiring and won’t carry over to other Lexus platforms.
