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

The W177 A35/A45 platform carries its 4Matic driveline low and far forward, and that mass shows up the moment you load the front axle into a roundabout or a damp B-road. XYZ Racing’s Super Sport coilover is built around that reality: a fast-road spec with enough range to keep the nose settled under trail-braking while still working as a daily commuter car.

Because this A-Class runs the 4WD rear subframe, the standard multi-link geometry is tighter on space than the front-drive A-Class, which is exactly why this kit uses a modified, rear-integrated damper mount rather than a bolt-on adaptation. The result is a rear end that stays located under power delivery through the rear differential, instead of a compromise fitted around it.

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

Ride height is adjustable independently of damping, so you can drop the car for a lower centre of gravity without giving up the suspension travel the 4Matic system needs to put power down cleanly out of a wet roundabout. The 36-way damping adjustment gives you a genuine spread between a setting that soaks up motorway expansion joints and one that controls body roll on a Sunday morning back-road run – not a token handful of clicks either side of stock. Because the rear mount is engineered specifically for this chassis’s integrated 4WD layout, the rear axle keeps its intended geometry rather than drifting out of alignment as the springs compress, which matters directly for how planted the car feels turning into a fast corner. Owners running the A35 or A45 will notice the front end holds its line under trail-braking instead of diving and pushing wide, and the reduced body movement makes the extra weight of the 4Matic hardware far less noticeable through direction changes.

About the Super Sport coilover

The Super Sport sits below XYZ Racing’s Circuit-focused ranges but above a comfort-biased setup, aimed squarely at drivers who want one car for the commute and the occasional track day rather than two dampers on rotation. Its 36-way adjustment covers a wide enough band that the same kit can be softened for a long motorway trip and firmed up for a circuit session without swapping parts. Independent ride height adjustment lets you set stance and corner weight separately from damping force, which keeps the geometry correct instead of forcing a compromise between "low" and "controlled." The monotube-style construction behind this adjustment range is what lets the damper resist fade over repeated inputs on rough UK B-roads rather than just smoothing out a single pothole. On the W177 4WD specifically, the rear-integrated mount design means the kit was engineered around this chassis’s actual rear subframe and driveshaft packaging, not adapted from a front-drive A-Class part. It’s a setup built for owners who use their A35 or A45 as a genuine daily driver that also gets booked onto a track day calendar a few times a year.

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

This kit is specified for the W177-generation A-Class with the A25 4WD driveline and φ53 strut diameter, covering model years 2019 through 2026. The rear damper uses the modified, integrated mounting design specific to the 4Matic subframe layout, so it is not interchangeable with front-drive A-Class kits. Confirm your car matches the W177 4WD chassis code before ordering, as coilover hardware differs between the 2WD and 4Matic rear ends.
