XYZ Racing Tarmac Rally Coilovers — Changan BENBEN ii 2006-2008

A Benben ii on a tarmac stage moves differently to almost anything else on the entry list: sub-900kg kerb weight, a short wheelbase, and a chassis never engineered for stage speeds over broken sealed surfaces. XYZ Racing’s Tarmac Rally coilover is built around that mismatch – not a road-going comfort setup with stiffer springs bolted on, but a damper tuned for the specific abuse of closed-road rally sections.

For CN01-chassis cars running sealed-stage events, the difference shows up where the tarmac stops being smooth: crown changes, patched sections, mid-corner ridges. This is the spec built for that, not for a trackday circuit with a consistent surface all lap.

What this coilover does for your 2006-2008 Changan(长安) Benben ii

On a car this light, small changes to damping have an outsized effect. Where a stock or worn set of dampers lets the Benben ii’s nose dive and skip over stage bumps – breaking front tyre contact right when you need it most – this coilover keeps the contact patch loaded through the impact instead of letting the wheel unweight. That directly increases traction off compressions and over crests, which on a front-driven car this light is where time on a stage is actually made or lost. Because the valving is set from XYZ’s own tarmac rally programme rather than a road-car baseline, the compression side is built to absorb a big hit without kicking the body up and unsettling the next turn-in. The result on the Benben ii specifically is a car that stays flatter and more predictable from one stage to the next, rather than one that gets progressively more nervous as the surface degrades.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally line is built specifically for sealed-surface rally stages rather than circuit track days or road use. The damping is tuned to soak up the impact of uneven, patched, or cambered tarmac – the kind of surface irregularity a closed rally stage throws up that a smooth circuit rarely does – rather than just controlling body roll. Big compressions, kerb strikes, and mid-corner bumps get absorbed without transmitting a harsh jolt back through the chassis, which keeps the body settled instead of unsettled into the next section. That control matters because it’s what keeps the tyre loaded and gripping rather than skipping across the surface, and on a stage car that traction is the difference between a clean line and a moment. XYZ set the valving using data and experience from its own tarmac rally programme, not a generic road spec adapted for motorsport, so the compression and rebound balance reflects what actually happens to a car running flat out on closed roads rather than a lab-bench guess.

Fitment for the Changan(长安) Benben ii (2006-2008)

This kit is specified for the Changan(长安) Benben ii, chassis code CN01, built between 2006 and 2008.
