XYZ Racing Circuit Master Coilovers — Toyota SUPRA J29/ A90 (Modified Rear Integrated) 2019-2026

The A90 Supra’s BMW-shared underpinnings give it a near 50:50 weight split and a double-jointed multi-link rear axle that reacts instantly to changes in spring rate and damping – a chassis built for a coilover with genuine adjustment range, not one fixed compromise setting. On both four- and six-cylinder cars the factory geometry already leans track-capable; what it lacks for sustained lap work is the ability to firm up compression and rebound independently once tyre and brake temperatures climb through a session.

The XYZ Racing Circuit Master coilover for the Toyota SUPRA J29/ A90 (Modified Rr Integrated) is built for exactly that scenario – repeated flying laps rather than one clean run. It brings full-range damping adjustment and a rear mounting revision specific to this chassis, so ride height and damping character can be set for sustained circuit work rather than a single fast pass.

What this coilover does for your 2019-2026 Toyota SUPRA J29/ A90 (Modified Rr Integrated)

With 9720 combinations available across the kit’s three adjustment knobs, you can set compression and rebound front and rear independently rather than accepting one blanket damping curve for a car that carries its weight almost evenly between axles. That range matters most under trail braking into a fast corner, where the Supra’s nose needs to load progressively without diving, and on corner exit, where the rear axle needs enough control to put power down without the multi-link geometry stepping out. Ride height adjustment also lets you correct the corner weights stock ride height doesn’t account for once you’re carrying fuel load or track ballast, keeping the corner balance consistent as tyre pressures and brake temperatures build through a session.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s coilover range, built for cars that see sustained sessions on a circuit rather than occasional fast-road driving. The kit offers 9720 total adjustment combinations through three separate knobs, giving separate control over compression and rebound rather than a single combined dial. XYZ runs this damper across its own racing programme internationally, and the adjustment range reflects what those cars actually need across a full session rather than one qualifying lap. The knobs work through a small-oil-passage design; over rough sections you may hear a faint noise as oil moves through those passages under compression – that’s a normal characteristic of the design, not a fault, and it has no bearing on damping control once you’re back on smoother circuit tarmac.
