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

The A90 Supra’s BMW-derived CLAR platform pairs a stiff, close-coupled chassis with adaptive electronic dampers tuned for road refinement, not for the compressions, crests and rapid direction changes a sealed tarmac stage delivers back to back. XYZ Racing’s Tarmac Rally coilover for the Supra J29/A90 replaces that factory damping logic with a mechanically adjustable strut built specifically to absorb repeated hits from broken and uneven asphalt.

This kit is the modified rear-integrated, cancellation-kit specification: the rear units are re-engineered to mate correctly with the Supra’s multi-link rear end, and the supplied cancellation kit removes the factory electronic damper signal so the dash stays clear once the OE adaptive units are gone. It’s built for crews running sealed-stage tarmac events, where the car needs to shrug off a hit mid-corner and keep the tyre loaded through the next one.

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

On a rough tarmac stage the difference is body control after the hit, not just before it. The Tarmac Rally spec absorbs the jolt from a big compression or pothole edge without kicking the rear axle sideways, which keeps the Supra’s naturally balanced weight distribution working for you instead of against you through the next direction change. Suppressing that shock at the body means the tyre stays in contact with the road longer under load, so the traction you paid for with the B58’s torque doesn’t get thrown away on a rippled straight. Because the electronic damping is cancelled rather than fought, the ride the driver feels through the wheel is the one XYZ Racing actually tuned in, not a compromise negotiated with the factory’s adaptive software. The result is a car that settles faster after a crest and holds its line into the next braking zone, which over a multi-stage rally adds up to fewer moments spent correcting and more spent committed.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically around sealed-stage work on broken and patched asphalt, where the surface changes character metre to metre. The damper is set up to soak up hits from uneven pavement and big compressions without transmitting that impact straight into the chassis, which is what keeps the tyre’s contact patch loaded and the car stable through the following turn rather than skipping sideways. That control is what lets a crew carry speed into a stage they haven’t pre-run at full pace, instead of backing off for fear of what the surface will do to the car. The valving and spring settings here come directly from XYZ Racing’s own tarmac rally programme, carried over rather than adapted from a circuit-focused product. For the Supra application specifically, the kit ships as the modified rear-integrated variant with the cancellation kit for the factory electronic damping included, so the whole system – mechanical damping, rear mounting, and the removal of the OE adaptive-damper signal – is sorted as one specification rather than left for the installer to reconcile.

Fitment for the Toyota SUPRA (2019-2026)

Built for the J29/A90 Supra, chassis code TO78-C, covering 2019 to 2026 production. This is the modified rear-integrated specification with the cancellation kit for the factory electronic damping, so it’s matched to Supras built with adaptive dampers from the factory rather than a passive-damper base spec. Confirm your build year falls within this range before ordering.
