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

The A90 Supra carries its weight low and rearward, but on a drag strip that weight only counts if it moves onto the rear contact patch in the instant the light goes green. XYZ Racing’s Drag Racing coilover for the Supra is set up around that single problem: getting mass onto the driven wheels before the tyre starts to spin, not into ninety-degree corners.

Because the A90 leaves the factory with electronic damping, this kit is built as a cancellation kit – it replaces the adaptive damper control with a fixed mechanical setup so the coilover, not the car’s computer, decides how the suspension behaves at launch. For a Supra bought or built with 0-400m runs in mind, that’s the starting point rather than an afterthought.

What this coilover does for your 2019-2026 Toyota Supra

Off the line, the springs and valving are set to load the rear axle hard and hold it there, shifting front-to-rear weight distribution the way the transmission and drivetrain actually put power down through launch. That extra load presses the rear tyres into the strip with more compression, which cuts down the moment of wheelspin right as the tyre first has to grip rather than roll. Less idle wheel movement at launch means less time spent correcting or waiting for the tyre to hook up, and more of the run spent accelerating. Through the rest of the pass, the same setup keeps the rear planted at speed instead of letting the Supra’s rearward weight bias unsettle the car as velocity builds, so 60-foot and top-end both benefit from the same geometry, and the electronic damping cancellation means none of that behaviour gets overridden by the factory adaptive system mid-run.

About the Drag Racing coilover

This is a coilover built around one manoeuvre: the 0-400m launch, whether the donor car is FWD, RWD or 4WD. Rather than tuning for mid-corner compliance, the valving and spring rates are chosen to control how much of the car’s weight transfers onto the driven axle the instant the clutch or torque converter loads up, and to hold that transfer through the run instead of letting it settle back to a neutral static balance. Forcing that weight onto the transmission’s wheels increases tyre compression at exactly the moment grip matters most, which shortens the window where the wheel is spinning rather than driving. The result is a suspension tuned for straight-line stability at speed as much as for the launch itself, since a car that squats hard off the line but wanders under power hasn’t actually gained anything. On the rear-driven A90 Supra platform, that means the rear axle is the one doing the work, and the kit is built to load it accordingly rather than splitting its attention across FWD or 4WD layouts it isn’t fitted to.

Fitment for the Toyota Supra (2019-2026)

This kit is specified for the J29/A90 generation Supra, chassis code TO78-C, covering the 2019 to 2026 model years, and is built as a cancellation kit for cars fitted with electronic damping from the factory – the mechanical valving in this coilover takes over that role rather than working alongside the OE control unit. Confirm your Supra’s build year falls within this range before ordering.
