XYZ Racing Racing Spec Coilovers — Ford FIESTA ST 2013-2017

The Mk7 Fiesta ST runs a torsion beam rear axle – a layout some dismiss, but one that, when the dampers are doing their job, delivers the kind of progressive, readable rear-end behaviour that makes FWD circuit cars genuinely quick. The XYZ Racing Racing Spec coilover is built for this application: competitive track sessions and time-attack, where the standard suspension’s compliant spring and damper rates leave measurable time on the table.

Settings for the Racing Spec were developed through direct participation in racing events including WTCC, so the calibration isn’t a desk-engineered approximation of what circuit conditions demand – it’s validated under race conditions. For Fiesta ST owners running substantial upgrades, the programme also accommodates fully custom-valved units built around your specific car and target circuit.

What this coilover does for your 2013-2017 Ford Fiesta ST

The Fiesta ST’s front MacPherson struts and torsion beam rear respond well to increased spring rates, but the stock dampers run out of control authority quickly under repeated hard laps. The Racing Spec addresses this with damping calibrated for the loads generated in aggressive track driving, not the road-circuit compromise found in the lower XYZ tiers. Better-controlled body motion keeps the front end honest in high-speed corners – where an understeering Fiesta loses the most time – and firmer spring rates reduce the geometry change that erodes mid-corner balance on the standard setup. For cars running upgraded anti-roll bars or a Quaife ATB differential, the Racing Spec’s stiffer baseline gives those modifications something to work against.

About the Racing Spec coilover

Sitting at the top of the XYZ Racing coilover range, the Racing Spec is developed explicitly for circuit racing and time-attack rather than as an upgrade path from a road-biased unit. The valving baseline comes from XYZ’s direct involvement in racing events including WTCC, giving the adjustment range competition-validated foundations rather than projected ones. Construction and thermal management target the demands of repeated hard-lap sessions, and the adjustment window reflects where performance driving actually operates.

Where the Fiesta ST has been subjected to aggressive modification – significant engine work, aero, or tyre specifications that substantially alter the car’s loading – the Racing Spec programme includes fully custom shock absorbers assembled around that specific package. Supply XYZ with your complete list of upgraded components and the circuit you are targeting, and the unit is built accordingly: the same process applied to factory-based or A-class race car builds.
