XYZ Racing Top Sport Coilovers — Ford FOCUS ST MK4 HATCHBACK (Cancellation Kit for Electronic Damping) 2019-2026

The Mk4 Focus ST left the Ford factory with Continuously Controlled Damping bolted to a 276bhp EcoBoost front end, and that electronic damping module is exactly what stops most owners going aftermarket. The XYZ Racing Top Sport coilover for the Ford Focus ST Mk4 Hatchback ships with the cancellation kit that takes CCD out of the loop cleanly, so the ECU stops throwing dash warnings the moment the OEM struts come off.

What you gain is a fully manual coilover under a hot hatch that was always going to outrun its factory damper map at a Donington trackday. Spring rates and damping move 30-50% beyond the street baseline, which is the territory the Mk4 ST’s stiff torsion-beam rear and torque-steer-prone front axle actually want when you start leaning on the Michelin Pilot Sport 4 S the car came on.

What this coilover does for your 2019-2026 Ford Focus ST Mk4 Hatchback

The Mk4 ST’s biggest on-road tell is the way the nose loads up mid-corner under throttle – 276bhp through the front wheels with an open-deck 2.3 EcoBoost sat over the front axle means body roll translates into understeer quickly on the standard setup. Raising spring rate by 2kg/mm and lifting damping force into Top Sport territory pulls the front end flatter through turn-in, so the eLSD has a stable platform to put torque down instead of fighting a rolling chassis. The 30-axle ride-height adjustment lets you drop the car to close the arch gap the Mk4 ST is criticised for without resorting to lowering springs that ruin damper travel. On a B-road the chassis stops floating over mid-corner bumps; on track, the rear axle stops skipping under trail-braking into a second-gear hairpin. Damping force is adjustable so the same car that did the school run on Monday can run Cadwell on Saturday.

About the Top Sport coilover

Top Sport is XYZ Racing’s track-day-with-a-commute spec, and the engineering brief is in the numbers. Damping force runs 30-50% firmer than the street range and spring rates step up by roughly 2kg/mm, settings drawn directly from XYZ’s Top Sport racing programme rather than guessed at on a test rig. The damper body is built to absorb the jolt when you cross a big mid-corner ridge – it suppresses the shock through the body fast enough that the contact patch stays loaded and the tyre keeps generating grip instead of skating. Construction is a full coilover replacement, height-adjustable independent of preload, with damping adjustment on each corner. The package is positioned for aggressive driving and circuit work where an off-the-shelf street coilover would run out of damper authority by the third lap.

Fitment for the Ford Focus ST Mk4 Hatchback (2019-2026)

Chassis code FO28-C, covering the 2019-2026 Mk4 ST hatchback – the 2.3 EcoBoost five-door, not the estate. The kit includes the CCD cancellation harness required to disable the factory Continuously Controlled Damping module, so the car will accept fully manual coilovers without a permanent dash fault.
