XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz A CLASS W177 A25 4WD φ53 (Modified Rear Integrated) 2019-2026

The W177 A-Class’s 4MATIC layout sends drive to the rear axle under load, and on a loose or broken tarmac stage that rearward torque shift has to be managed by dampers that can keep the back end settled while the front still turns in. XYZ Racing’s Tarmac Rally coilover is built around that exact demand, not generic road comfort.

For the A25 4WD variant with the modified rear-integrated setup, this kit replaces the factory strut and spring assembly front and rear with a purpose-tuned rally damper, so the car can take repeated hits from broken surfaces, mid-corner camber changes and compression events without the body pitching or the rear stepping out unpredictably.

What this coilover does for your 2019-2026 Mercedes Benz A Class W177 A25 4WD φ53 (Modified Rr Integrated)

On a stage, the biggest threat to pace is a jolt through a mid-corner compression unsettling the chassis at the exact moment the driver needs grip. This damper is calibrated to absorb that impact from uneven pavement and big compressions without the shock passing straight through to the body, which keeps the tyre loaded and in contact rather than skipping over the surface. That translates directly into more usable traction when the road camber shifts under the 4WD system’s rearward torque bias. The stability this brings shows up as a car that holds its line through fast direction changes on tarmac stages rather than requiring constant correction, and it lets the rear-integrated mounting keep working as intended instead of transmitting harshness into the cabin structure.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s damper for sealed-stage tarmac events, where the surface is fast but rarely smooth. Internally, the valving is set up specifically to soak up big hits – kerbs, cambers, mid-corner ruts – rather than transmit them into the chassis as a shock, which is what causes a car to skip and lose the tyre’s contact patch mid-stage. The settings supplied on this kit come directly from XYZ’s own tarmac rally racing programme, carried over rather than derived from road-tuning data. That background matters because a stage damper has to do two contradictory jobs at once: control body movement hard enough to hold a line, while staying compliant enough that the tyre stays planted across broken surfaces. This is the spec XYZ runs when both of those have to happen at the same time.

Fitment for the Mercedes Benz A Class W177 A25 4WD φ53 (Modified Rr Integrated) (2019-2026)

This kit is built to the ME51-3 chassis code, covering the W177-generation A-Class A25 4WD from 2019 to 2026 with the modified rear-integrated mounting configuration. Confirm your car matches the A25 4WD φ53 modified rear-integrated spec before ordering, as this fitment is specific to that rear mounting arrangement rather than the standard rear setup.
