XYZ Racing Tarmac Rally Coilovers — Subaru IMPREZA WRX/ WRX STI AWD 4WD 2015-2021

Sealed-stage tarmac rally punishes a chassis in a way public roads never do – full-bore compressions over crested apexes, kerbs taken at speed, and camber changes that arrive with no warning. The WRX/STI’s AWD platform already puts power down hard through both axles; what it needs from its dampers is control that survives repeated big hits without the body kicking sideways mid-corner.

XYZ Racing’s Tarmac Rally coilover is built around exactly that brief. It’s tuned to absorb the jolt of a big compression – a rut, a mid-corner ridge, a kerb strike – without transmitting the impact straight into the chassis, so the STI’s rear subframe and diff stay settled rather than getting knocked off line.

What this coilover does for your 2015-2021 Subaru IMPREZA WRX/ WRX STI AWD 4WD

On a stage-spec WRX or STI, the damper’s job is to keep both axles loaded evenly through the kind of hits that would unsettle a standard setup. Effective shock-body suppression means less energy bouncing back up through the springs after a big compression, so the tyre stays in contact with the road instead of skipping across it after impact. That translates directly into traction – the car puts its AWD advantage down through the surface instead of losing it to an unsettled rear end mid-corner. The result on a tarmac stage is a car that holds its line through a sequence of rough sections rather than needing a lift to reset itself, and a driver who can commit to the next compression because the last one didn’t throw the chassis off balance.

About the Tarmac Rally coilover

This is a damper built specifically around tarmac rally use rather than adapted from a circuit or fast-road base. The valving is set up to deal with big, sudden impacts – the kind a stage throws up that a track kerb or pothole never quite matches – absorbing the hit rather than passing it through to the body. That shock-suppression work is the core of the design: it’s what keeps the tyre planted and the car stable when the road surface stops cooperating. XYZ Racing has carried its settings over from its own tarmac rally programme, so the compression and rebound behaviour reflects what’s actually needed at stage pace rather than a generic fast-road compromise. For the WRX/STI, that means a setup calibrated for a heavier, power-everywhere AWD chassis rather than a lighter FWD or RWD platform.

Fitment for the Subaru IMPREZA WRX/ WRX STI AWD 4WD (2015-2021)

Built for the SU12 chassis – the AWD Impreza WRX and WRX STI produced from 2015 to 2021. Confirm your build year falls within that span before ordering, since Subaru’s Impreza generations shift chassis code and hardpoints at the boundaries.
