XYZ Racing Racing Spec Coilovers — Toyota SUPRA J29/ A90 (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2019-2026

The A90 Supra’s factory adaptive dampers are tied into the car’s electronic stability systems, which is exactly why a straight coilover swap on this chassis needs a cancellation kit alongside it – remove the electronics without the workaround and you’re left with fault codes and a dash full of warnings. This Racing Spec kit replaces the factory unit entirely and integrates with the modified rear end, giving you a fixed mechanical setup built for time-attack and circuit driving rather than a compromise that still talks to the car’s original ECU logic.

For an A90 owner running regular track sessions, that matters more than it does on a car that only sees the odd trackday. The GR-derived platform carries real weight over the front axle and a rear end that needs to stay planted under trail-braking into slow corners, and Racing Spec is XYZ’s answer for owners who’ve already outgrown a fast-road setup.

What this coilover does for your 2019-2026 Toyota SUPRA

Racing Spec damping settings come directly from XYZ’s involvement in WTCC-level competition, so the valving on this kit is derived from cars actually turning wheel-to-wheel rather than bench-tested for a road ride. On the Supra’s rear-integrated setup, that translates into a chassis that resists squat under power out of slow corners and keeps the rear axle loaded through direction changes, rather than letting the rear step out under trail-braking. Ride height is adjustable independently of the damping, so you can get the A90’s front-heavy stance level and the corner weights sorted without touching the settings you’ve chosen for the circuit. The cancellation kit means none of this fights the car’s electronics – what you set at the damper is what the wheel actually does.

About the Racing Spec coilover

XYZ builds Racing Spec dampers specifically for track and race use, with settings pulled from real events including WTCC rather than generic road-car tuning. Where a car has already had aggressive supporting modifications – bigger brakes, wider tyres, a different aero package – XYZ can produce a custom-valved shock absorber to suit, built around details the owner supplies about the car and the circuit it’s run on. For the A90 Supra specifically, that custom-build route is worth knowing about if your car has moved past a fairly standard track setup, since a shock tuned around your actual brake bias and tyre choice will behave differently to an off-the-shelf valving. The Racing Spec line sits above XYZ’s fast-road ranges in both adjustability and the depth of track data behind the settings, which is the point of choosing it over a lower-tier kit for a car doing serious lap time work.

Fitment for the Toyota SUPRA (2019-2026)

This kit is built for the J29/A90 Supra, chassis code TO78-C, covering 2019 to 2026 production, in the modified rear-integrated configuration paired with the electronic damping cancellation kit. Confirm your Supra falls within this fitment window and that you’re running (or planning) the rear-integrated modification before ordering, since the cancellation kit is matched specifically to that configuration.
