XYZ Racing Tarmac Rally Coilovers — Honda CIVIC SI FB6/FG4 TYPE 2 2012-2015

The ninth-gen Civic Si saloon was never built with broken tarmac in mind. The FB6/FG4 chassis runs a torsion-beam rear and a relatively soft factory damper tune that copes well with a smooth circuit but skips, bottoms and unloads the inside-rear over the kind of mid-stage compressions a UK closed-road stage throws at it. The XYZ Racing Tarmac Rally coilover for the 2012-2015 Honda Civic Si is the answer to that specific problem.

This is a stage-tarmac damper, not a circuit setup softened off. The valving has been built around impact absorption first and platform control second, so the front axle stays planted through gravel cuts, kerb strikes and mid-corner ridges instead of pattering and washing wide. For a 2.4-litre K24Z7 saloon being driven on Targa, sprint or sealed-surface rally events, this is the right starting point.

What this coilover does for your 2012-2015 Honda Civic Si

The Tarmac Rally valving lets the damper soak up sudden vertical inputs – cresting compressions, drainage seams, joint repairs – without transmitting the shock into the chassis or unsettling the contact patch. On a front-drive Civic Si that lives or dies by front-tyre traction on corner exit, that translates directly into earlier throttle and less scrub. Body control under braking improves noticeably, the nose stops diving into long-radius bends, and the rear torsion beam stops hopping mid-corner when one wheel finds a patch of broken surface. Ride height drops to a sensible stage figure without bottoming the bump stops, and the platform stays predictable lap after stage. None of this requires a circuit-stiff spring rate, which is the point.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s dedicated sealed-stage rally damper, and the brief is narrower than the company’s broader Super Sport or Top Sport ranges. It is engineered specifically to absorb the jolt of large impacts, suppress secondary body movement after the hit, and keep the tyre loaded through the rebound stroke – the three things that decide whether you carry pace through a rough stage or back off and lose seconds. The damping curves come straight out of XYZ’s own Tarmac Rally racing programme, which means the settings have been arrived at on real closed-road events rather than dyno simulation. Construction follows XYZ’s standard coilover hardware – height-adjustable lower mount, pillowball top mount where the platform allows, and damping adjustment on the unit itself – but the internal tune is the part that matters here.

Fitment for the Honda Civic Si (2012-2015)

This kit is built for the FB6/FG4 saloon Civic Si with chassis code HN68, covering the 2012 to 2015 model years. It suits the K24Z7 2.4-litre Si saloon as sold in North American specification, which UK owners typically run as a personal import. Confirm your year, body style and trim against the listing before ordering.
