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

The MK4 Focus ST left the factory with Continuously Controlled Damping wired into the ECU, and that is exactly the system this kit is built to replace. Strip the CCD struts off a 2.3 EcoBoost hatch, drop these in, and the cancellation harness keeps the dash quiet while a fully mechanical damper does the work underneath. For sealed-stage tarmac use, that swap matters: the factory adaptive system is tuned for road comfort modes, not for repeated kerb strikes and compression loads on a closed stage.

XYZ Racing’s Tarmac Rally spec is the right pick if you are running a MK4 ST on tarmac stages, hillclimbs, or sprint events where the surface is broken but fast. The compromise here is bias toward stage compliance and tyre contact, not flat-floor circuit stiffness.

What this coilover does for your 2019-2026 Ford Focus ST MK4 Hatchback

The Tarmac Rally valving is built around absorbing big single-hit inputs – kerbs, expansion joints, broken tarmac edges – without unloading the front axle on the rebound. On the MK4 ST that translates into a front end that stays planted under trail-braking instead of skating across mid-corner ripples, which is the dominant failure mode of the standard CCD setup when you push it past road pace. The cancellation kit is the other half of the story: with the electronic damping signal terminated cleanly, you get no fault codes, no limp-mode behaviour, and no permanent dash light. Stance drops to a workable rally ride height, and the chassis finally responds to spring rate and damper input rather than to a software map. Traction at the driven front axle improves noticeably on cold, broken surfaces, which is where a 280bhp turbocharged hatch otherwise spends a lot of energy lighting up an inside wheel.

About the Tarmac Rally coilover

This damper is built specifically for tarmac rally use, with valving developed from XYZ Racing’s own tarmac rally programme. The construction is tuned to absorb the impact of uneven pavement – the kind of mid-corner compressions and crested jumps that destroy a circuit-spec damper within a season. When the car crosses a big bump, the unit soaks the jolt rather than transmitting it through the chassis, which keeps the tyre loaded and increases mechanical grip on broken surfaces. Shock to the body is suppressed, vehicle stability holds through compression zones, and the handling balance stays predictable when the surface stops being. The settings carried over into this kit come directly from XYZ Racing’s tarmac rally racing experience, so the baseline tune is already in the right window for sealed-stage use rather than something you have to discover on event.

Fitment for the Ford Focus ST (2019-2026)

This kit fits the MK4 Focus ST Hatchback, chassis code FO28-C, model years 2019 through 2026. It is the specific variant for cars fitted with Continuously Controlled Damping from the factory, and includes the cancellation harness required to disable the electronic damping system without throwing fault codes.
