XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz A CLASS W177 A25 4WD φ53 2019-2026

The A25 4WD’s dual-clutch power delivery through all four corners changes what a damper needs to do on a closed stage – traction off the line matters as much as body control mid-corner. On broken tarmac, that grip window closes fast if the suspension can’t absorb a compression before the next crest. These Tarmac Rally coilovers are built around that exact demand: soak up a big hit without unsettling the chassis, then get the tyre back onto the road before the next one arrives.

For the W177 A25 running sealed-stage tarmac rally, that means damping calibrated for repeated, unpredictable inputs rather than a single smooth circuit line. The goal isn’t ride comfort – it’s keeping all four contact patches loaded through the kind of surface changes a rally stage throws up that a track never does.

What this coilover does for your 2019-2026 Mercedes Benz A Class

Fitted to the A25 4WD, the damper’s primary job is absorbing impact from uneven surfaces without transmitting the jolt straight into the body structure – on a stage full of camber changes and mid-corner bumps, that’s the difference between a car that stays planted and one that skips wide. Suppressing that shock through the chassis keeps the tyre’s contact patch working, which on a 4WD platform translates directly into traction you can actually use out of a hairpin. The stability this brings lets you commit to a line through a compression instead of backing off to protect the car. Every setting on this kit comes from XYZ Racing’s own tarmac rally programme, so the compression and rebound behaviour reflects what’s actually needed when a car is being driven at the limit over broken surfaces, not estimated from road-going assumptions.

About the Tarmac Rally coilover

The Tarmac Rally is a purpose-specific damper design, not a general fast-road coilover repurposed for stage work. Its core job is absorbing the impact of uneven pavement – the broken, patched, and cambered surfaces typical of a closed tarmac stage – without letting that impact travel into the body as shock. Big compressions across large bumps get suppressed at the damper rather than the chassis, which keeps the tyre loaded and its contact patch working instead of skipping. That control is what XYZ Racing describes as delivering vehicle stability and handling that stays consistent as the surface deteriorates through a stage. The valving and spring settings are drawn directly from XYZ Racing’s own tarmac rally experience, meaning the behaviour has been shaped by actual stage conditions rather than a lab spec sheet.
