XYZ Racing Tarmac Rally Coilovers — Subaru IMPREZA STI GRB/GVB/GRF/GVF 4WD 2007-2014

The Impreza STI’s permanent four-wheel-drive layout and DCCD centre differential were built for exactly this kind of work: point-to-point stages where grip swings from clean tarmac to gravel-dusted apex without warning. XYZ Racing’s Tarmac Rally coilover is calibrated for that discipline specifically – sealed-stage pace on closed public roads, not the smooth, swept surfaces of a circuit.

On the GRB/GVB/GRF/GVF generation that means damping set up to keep all four corners loaded through compressions, crests and mid-corner ruts, rather than simply controlling body roll the way a track-day coilover would. It’s a chassis built for this job from the factory, and this kit is set up to keep it doing that job on rough tarmac.

What this coilover does for your 2007-2014 Subaru Impreza STI GRB/GVB/GRF/GVF 4WD

Stage tarmac is rarely flat. Broken surfaces, patched sections and camber changes hit the chassis harder and more often than a circuit lap ever will, and this is where the kit earns its name. The damping absorbs the impact of that uneven pavement instead of transmitting it straight into the body, which keeps the Impreza’s weight settled through a sequence of corners rather than pitching after every ripple. Big hits – a compression after a blind crest, a pothole mid-braking zone – get soaked up rather than kicked back through the chassis, which matters on a car putting power down through all four wheels via a centre diff that’s sensitive to load transfer. Suppressing that shock through the body also keeps the tyre’s contact patch working, so traction stays consistent on corner exit instead of spiking and breaking loose. The result is a car that holds its line and its footing over the kind of surface a tarmac rally stage actually throws at it, not the surface a showroom test drive does.

About the Tarmac Rally coilover

This is a damper built specifically around tarmac rally use rather than adapted from a circuit spec. Its primary job is absorbing impact from the broken, uneven road surfaces typical of closed-road stages, taking the jolt out of big hits so the body stays composed instead of getting knocked off line. That control does double duty: it suppresses shock transmission through the chassis and keeps the tyre loaded against the road, which is where the traction gain actually comes from – a tyre skipping over a rough surface can’t put power down, one that stays planted can. The stability that comes from this combination is what lets a driver commit to a line through a fast section rather than backing off for the next unknown bump. Crucially, the settings behind this kit come from XYZ Racing’s own tarmac rally programme, not a generic circuit damping curve retuned for road use – the calibration reflects what the discipline actually demands.
