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

The A90 Supra’s B58 straight-six sits behind a front axle developed alongside BMW’s Z4, and the adaptive damping electronics that ship on the car will throw fault codes the moment you bolt on a conventional coilover without dealing with them first. This Top Sport kit for the Toyota Supra J29/A90 is built with the cancellation loom already accounted for, so the ECU stops looking for a damper signal that no longer exists.

Top Sport sits in XYZ Racing’s range for owners who want a car that’s genuinely usable on the road but gets driven hard on track days a handful of times a year. It’s not a full race set-up, and it’s not a soft street compromise either – it’s tuned for the gap between the two, which is exactly where most A90 owners actually live.

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

With damping increased 30-50% and spring rates up roughly 2kg/mm over the standard road setting, the Supra’s nose stops diving under trail braking and the rear stays flatter through direction changes, which matters on a chassis that already has a strong front-to-rear weight balance to exploit. The stiffer control checks the shock body movement that shows up as vagueness over mid-corner bumps, so the tyre stays in contact with the road instead of skipping across it – you’ll feel that most under load, where the standard suspension starts to give up composure. Big compressions, kerbs, motorway expansion joints, get absorbed rather than transmitted straight into the cabin, because the increased damping is specifically calibrated to catch a hard hit without locking the wheel up. The net result on the B58-powered Supra is a car that puts its power down more consistently out of a corner, because the tyre’s contact patch isn’t being upset by an underdamped rear axle.

About the Top Sport coilover

Top Sport is XYZ Racing’s track-day-and-back specification, built from the same damping philosophy the brand applies to its motorsport programmes but recalibrated for cars that still need to be driven home afterwards. Damping force is raised 30-50% over the street baseline, paired with a spring rate increase of around 2kg/mm, giving enough control to suppress body movement over aggressive inputs without turning the ride brittle on a normal commute. The construction is aimed squarely at absorbing hard hits – big bumps, kerbs, compressions under braking – rather than just stiffening the car for its own sake, which is why the emphasis throughout is on keeping the tyre loaded and gripping instead of skipping. For the Supra specifically, that translates into a kit engineered around the car’s adaptive-damper delete, so the electronics are dealt with as part of the install rather than left as an afterthought. It’s aggressive driving hardware first, with enough manners left over for the drive to and from the circuit.

Fitment for the Toyota SUPRA J29/ A90 (Modified Rr Integrated) (Cancellation Kit for Electronic Damping) (2019-2026)

Built for the Toyota Supra J29/A90 chassis (TO78-C) across the 2019-2026 production run, this kit is specified for cars with the modified rear-integrated set-up and includes the cancellation kit needed to run non-adaptive dampers on a chassis that left the factory with electronic damping control. Confirm your Supra sits within this chassis code and year range before ordering, and check which electronic damping variant your specific car carries.
