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

The A90 Supra left the factory with BMW-sourced adaptive dampers wired into its stability and traction electronics, which is precisely the problem a genuine rally build has to solve before it can run loose surfaces at pace. This Pro Rally kit is built as what XYZ Racing class the "professional type" of gravel and snow suspension – designed to go in once the rear end has already been modified to accept it, rather than bolting straight onto the untouched factory subframe the way an amateur-spec kit would.

That distinction matters on a car like the Supra, where the standard rear geometry and electronic damping control were tuned for road and circuit use, not for absorbing repeated compression hits over rough, unsealed stages. Because the factory ECU expects to see its own damper signal, this specification is paired with a cancellation kit for the electronic damping system, so the car stops flagging faults once the mechanical dampers take over.

What this coilover does for your 2019-2026 Toyota SUPRA

Once the rear conversion is in and the electronic damping is cancelled, the Supra gets a fixed, mechanically-controlled damping platform built to survive the compression cycles of gravel and snow stages rather than the smooth, repeatable loads of tarmac. That means predictable wheel control over crests and ruts instead of a factory system hunting for a setting it was never calibrated to find off-road. Ride height and corner-weighting become adjustable to suit the stage, letting you set the Supra’s naturally low, wide stance up for the ground clearance a rally car actually needs. With the adaptive damping electronics out of the loop, the suspension behaviour stops depending on drive-mode software and instead reflects exactly what’s dialled into the coilover itself – the same logic every serious rally build is set up around.

About the Pro Rally coilover

XYZ Racing splits its gravel and snow suspension range into two distinct approaches: an amateur type that fits directly to the original chassis, and this professional type, built for cars whose bodywork and rear mounting points have already been modified to take it. That’s the category this Supra application sits in – a kit engineered around a reworked rear end rather than a compromise that has to share space with the standard subframe geometry. The construction favours the robust, rebuildable damper architecture associated with top-flight rally competition, where stages punish suspension components far harder and more repeatedly than any circuit lap. Because the kit is matched to a modified rear layout, the damping and spring specification can be set closer to what a competition car actually needs, rather than diluted to also cope with an unmodified factory mounting point.

Fitment for the Toyota SUPRA (2019-2026)

This kit is specified for the Toyota Supra J29/A90 platform, chassis code TO78-C, covering the 2019 to 2026 model years, and is built specifically for cars with the modified rear-integrated conversion already carried out. It is supplied with the cancellation kit required to disable the factory electronic damping control, so the mechanical suspension runs without ECU interference. Confirm your Supra’s rear end has been converted to accept a professional-type kit before ordering, as this specification is not intended for an unmodified factory subframe.
