XYZ Racing Circuit Master Coilovers — Ford FIESTA ST 2013-2017

The Mk7 Fiesta ST left the factory with a famously lively rear end – the twist-beam axle and sub-1,200kg kerb weight let it rotate on a trailing throttle in a way few front-drive hatches manage. Run it through a full circuit session, though, and the standard dampers run short of control, the body leans onto its outer edge and that playful tail turns vague. The XYZ Racing Circuit Master coilover for the Ford Fiesta ST (2013-2017) is built for that exact scenario: sustained circuit lap-time work where the suspension has to stay composed long after the standard kit has gone soft.

Circuit Master sits at the competition end of the XYZ Racing range, alongside the Drift Spec and Tarmac Rally builds. It is a three-knob adjustable damper for drivers who treat the ST as a track car first and a road car second, with the bandwidth to separate low-speed body control from high-speed compliance.

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

Drop the ride height and the ST’s centre of gravity falls with it, cutting the body roll that blunts the car’s quick turn-in. The three independent adjustment knobs let you firm up low-speed damping for sharper bite into a corner while keeping enough high-speed give to ride over kerbs without unsettling the chassis. That control is what makes the Fiesta’s lift-off rotation usable rather than nervous – you can lean on the rear axle knowing the damping will catch it. On the brakes into a slow hairpin, the firmer platform holds the nose flatter, so the front tyres keep their contact patch when you need them most. The net result is a Fiesta ST that stays consistent deep into a session instead of fading as the laps stack up.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s circuit-focused damper, developed and tested by XYZ Racing teams competing on international circuits. Each unit carries three separate adjustment knobs, and across their combined ranges they offer 9,720 distinct damping settings – enough granularity to tune the car to a specific track surface or driving style. The damping circuit uses a small-orifice oil passage design; over large bumps the oil is forced through that narrow passage, which can produce a faint noise. This is normal behaviour and not a fault. Because the kit is engineered for smooth circuit surfaces rather than broken roads, that characteristic is a non-issue where the car is meant to be driven. It shares its core design with XYZ’s other competition specs, including the Racing, Drift and Tarmac Rally builds.
