XYZ Racing Top Sport Coilovers — Ford FOCUS ST MK4 HATCHBACK 2019-2026

The Mk4 Focus ST arrived with a 276bhp 2.3 EcoBoost up front, an electronic LSD, and a chassis that Ford’s RS team had clearly spent time on – but also with a passive damper tune calibrated for a forgiving showroom test drive. Owners learn quickly that the front axle still loads up hard under trail-braking into a damp Cadwell hairpin, and that the standard springs let the nose pitch enough to upset what the e-diff is trying to do on corner exit.

The Top Sport coilover for the Mk4 ST is set up to fix that without ruining the car for the school run. It is the kit you fit when the ST is your daily and your trackday car, and you have decided the factory damping has reached the end of its useful life.

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

Spring rates lifted roughly 2kg/mm over a street tune, paired with damping wound up around 30 to 50 percent firmer, change how the front of the ST behaves under load. Turn-in is sharper because the nose no longer dives onto the bump-stops, and the eLSD has a flatter platform to put 415Nm down through the front Michelins. Body roll drops, which means the inside-rear stops lifting clear of the tarmac as early through quicker corners. Mid-corner bumps – the sort that send a stock ST skipping wide at Druids – get absorbed rather than translated straight into the steering rack. Ride height is adjustable so you can drop the arches over the 19-inch wheels without binning the geometry, and rebound control means the car settles after a kerb strike instead of pogoing across the next apex.

About the Top Sport coilover

The Top Sport sits in XYZ Racing’s range as the kit drawn directly from their racing programme and then softened, fractionally, to remain liveable on UK B-roads. Spring rates run roughly 2kg/mm above the street-orientated Super Sport, with damping recalibrated 30 to 50 percent firmer to match. The brief is impact absorption under aggressive driving – soaking up the jolt from sharp ridges and kerb strikes, suppressing the secondary body movement that follows, and keeping tyre contact loaded for traction out of the corner. Height-adjustable via the lower mount to protect spring travel, with damping settings carried over from XYZ’s race work and tuned for sustained track use rather than a single hot lap. It is positioned as the kit for occasional trackday running where the car still needs to drive home afterwards.
