XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz B CLASS W247 φ53 (Rear Twist- beam Suspension) 2019-2026

The W247 B Class runs a twist-beam rear axle, not an independent multi-link setup, which changes the whole game for stage work. Twist-beam cars transfer load through the beam itself, and on broken tarmac that means the rear end can skip and hop if the damper isn’t controlling it properly. The XYZ Racing Tarmac Rally coilover is built specifically for that fight – sealed-stage pace over surfaces that punish a soft factory setup.

This is not a fast-road spring-and-shock upgrade dressed up in rally branding. It is a damper tuned for repeated hard hits – crests, compressions, and the kind of mid-corner bumps that unsettle a nose-heavy B Class hatch running on a twist-beam rear.

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

On a car with a twist-beam rear, wheel control under compression is everything – there’s no independent geometry to fall back on when one side loads up mid-corner. The Tarmac Rally kit is calibrated to absorb sharp inputs from broken road surfaces without kicking the body, which keeps the rear tyre planted and the contact patch working instead of skittering across ruts and camber changes. That translates directly into traction out of tighter stage corners, where a twist-beam car can otherwise get light and vague. Front-end response sharpens too, since the reduction in body movement means less of the B Class’s kerb weight is being thrown around under transitions. The result is a car that settles faster after a bump instead of still moving when the next one arrives.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line around one job: absorbing the impact of uneven pavement without letting that impact reach the chassis. The damper is calibrated to soak up hard, sudden inputs – the kind of big compressions a stage throws up – while suppressing the secondary body movement that follows a bad hit. That control does double duty: it protects the chassis from repeated shock loading over a stage distance, and it keeps the tyre’s contact patch working so traction doesn’t drop off when the surface gets rough. XYZ describes the result as stability that lets the driver feel the car properly through a corner rather than fighting it, and every valving decision in this kit comes directly from their own tarmac rally programme rather than a generic fast-road baseline. For a twist-beam platform like the W247, that pedigree matters – the settings account for how a beam axle actually moves under load, not just how a multi-link car does.

Fitment for the Mercedes Benz B Class W247 Φ53 (Rr Twist-beam Suspension) (2019-2026)

This kit is built for the W247-generation B Class fitted with the twist-beam rear suspension, chassis code ME47, covering the 2019 to 2026 model years. Confirm your car uses the twist-beam rear axle (rather than a multi-link variant) before ordering, as the two setups require different rear damper geometry.
