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

The W177 A-Class in 4Matic guise carries its turbo four and transfer hardware ahead of the front axle, and that extra mass shows up as nose-heavy weight transfer the moment you brake hard into a corner. XYZ Racing’s Street Advanced coilover kit is built to manage that load shift without turning the car into a plank on the commute.

For the A25 4WD φ53 fitment with the modified rear integrated mount, this is a kit aimed squarely at drivers who want one car for the school run and the odd track day, not two separate setups. It replaces the factory MacPherson strut and multi-link geometry with a coilover platform that keeps ride height and damping in your hands.

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

Lowering the centre of gravity on a chassis this nose-heavy pays off immediately in turn-in response, because less weight is transferring onto an already-loaded front axle mid-corner. The 720-way damping adjustment lets you soften the front for broken UK B-roads, then firm both ends up before a circuit session without swapping parts. Because the kit is matched to the 4Matic’s specific strut and rear mounting points, including the modified rear integrated hardware this fitment requires, ride height drops evenly front to rear rather than skewing the car’s natural balance. Owners running this on the road report tighter body control under trail-braking, which matters on a platform that already asks a lot of its front tyres.

About the Street Advanced coilover

Street Advanced sits as XYZ Racing’s most widely fitted line, refined over multiple seasons and validated through use in competition by racing teams worldwide rather than developed purely on paper. It is built for cars that see genuine road use with occasional track days layered on top, which is exactly the brief for a 4Matic hatchback. The headline spec is 720 damping increments, giving a far finer resolution between comfortable and firm than a basic two-way adjuster, so you’re not choosing between "soft" and "harsh" with nothing usable in between. Construction favours durability under repeated adjustment and everyday load rather than one-weekend race hardware. For anyone who wants their A-Class to feel sharper without living with a compromised daily ride, this is the specification XYZ built for that exact brief.

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

This kit is engineered specifically for the W177-generation A-Class in A25 4WD trim, chassis code ME51-3, covering the 2019 to 2026 model years. The φ53 strut body and modified rear integrated mounting are matched to this exact 4Matic configuration, so fitment does not carry across to front-wheel-drive A-Class variants or other chassis codes in the range.
