XYZ Racing Racing Spec Coilovers — Chevrolet EPICA 2006-2014

The Epica is an unusual track-day starting point – a mid-2000s D-segment saloon with a transverse layout, a long wheelbase for its class, and a kerb weight that punishes any damper not built for sustained heat. That is precisely the brief the XYZ Racing Racing Spec coilover is written against. This is not a fast-road kit asked to moonlight at Donington; it is a circuit damper that happens to fit a Chevrolet Epica chassis code CH03.

For owners running the Epica in time-attack or club-level circuit work between 2006 and 2014 production years, the Racing Spec sits at the top of the XYZ ladder. The damping logic is taken directly from XYZ’s involvement in WTCC-level competition, then re-valved for a saloon of this mass and geometry.

What this coilover does for your 2006-2014 Chevrolet Epica

Drop the Epica onto the Racing Spec and the first thing that goes is the floaty mid-corner roll the standard car carries on its softer factory tune. Body movement is shortened, the platform stays flatter under trail-braking, and the front axle starts loading more predictably as you wind in steering lock. On a heavy front-drive saloon that has historically pushed wide at the apex, that is the difference between rolling onto the throttle early and waiting for the nose to settle.

Sustained lap work is where this kit earns its keep. The valving is built to hold its character through repeat heat cycles rather than fade after three flying laps. Spring rates are set firm enough to control the Epica’s mass without spiking the kerb strikes, and the ride height adjustment lets you set a corner-balanced stance that suits the circuit you actually run.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s circuit-only damper, and the company is open about its origin: the settings were obtained from direct participation in WTCC race events, then transferred into the catalogue series. That pedigree matters because the valving curves carry over rather than being theorised in CAD.

XYZ also offers a custom-spec route on this product. If the Epica has been pushed beyond catalogue assumptions – aggressive aero, sticky semi-slicks at the edge of homologation, factory-style racing modifications or A-class race prep – the manufacturer will accept detailed information on the upgraded parts and the specific circuit being run, and build the shock absorbers to that brief. That is rare at this end of the market and worth flagging when you spec the kit. Construction is consistent with the rest of the XYZ catalogue: rebuildable damper bodies, height adjustment independent of preload, and serviceable internals for season-long use.

Fitment for the Chevrolet Epica (2006-2014)

This kit is built specifically for the CH03 chassis Epica across the full 2006 to 2014 production span. The supplied data covers the model line as a whole; confirm engine variant and trim against your V5 before ordering so the spring-rate pairing matches what you actually run.
