XYZ Racing Street Advanced Coilovers — Mercedes-Benz A CLASS W177 A35 4WD φ55.5 2019-2026

The W177 A35’s AMG Ride Control dampers come from the factory already firm, tuned around a nose that carries the turbocharged four-cylinder and the full 4Matic driveline ahead of the bulkhead. XYZ Racing’s Street Advanced coilover kit for this chassis, built to the A35’s φ55.5 strut diameter, replaces that fixed-rate factory unit with 720 damping-adjustment ways, so the same car that copes with a broken B-road on a Tuesday can be wound up for a trackday on the weekend.

Street Advanced sits between an out-and-out circuit kit and a comfort-biased road spring: height and damping both move independently, so an A35 owner running bigger brake pads and stickier rubber for track days can back the compression off again for the drive home.

What this coilover does for your 2019-2026 Mercedes-Benz A-Class W177 A35 4WD

Ride height adjusts independently of spring preload, so you can correct the factory’s slightly high stance without upsetting the corner-weight balance the 4Matic system needs to put power down cleanly out of a wet roundabout. The 720-way damping range means the front end, already loaded by the engine and transfer case, can be firmed up enough to stop the nose diving into apex kerbs at a track day, then softened again so the car doesn’t crash over drain covers on the school run. Because the kit adjusts rather than just lowers on a fixed drop, you keep usable geometry angles even after dropping the car, which matters on a chassis whose front struts already carry more static weight than a standard front-drive A-Class. Body roll drops noticeably against the stock Ride Control set-up, sharpening turn-in on the tighter, second-gear corners where the A35’s four-wheel-drive traction advantage is otherwise wasted by body movement.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s biggest seller, built from feedback gathered across years of use in club and national-level racing, and pitched deliberately at drivers who want one set of coilovers for both a normal commute and the occasional circuit outing. The 720-way damping adjustment is the headline figure: fine enough steps that you can find a setting for a rough B-road and a completely different one for a smooth circuit surface, rather than living with the single compromise a fixed-valve shock forces on you. Construction follows XYZ’s usual monotube shock body, built in this application to the A35’s φ55.5 strut diameter so it’s a direct swap for the factory unit rather than an adapted item. Height adjustment sits apart from the damping circuit, which lets an owner correct ride height after fitting the kit without having to re-tune compression and rebound from scratch. It’s built as everyday-usable kit first and track kit second – the adjustment range exists so one car can do both jobs rather than needing a second set of coilovers for road use.

Fitment for the Mercedes Benz A CLASS W177 A35 4WD φ55.5 (2019-2026)

This kit is built for the W177-generation A35 4Matic, chassis code ME51, covering 2019 to 2026 model years, and specced to the A35’s φ55.5 front strut diameter rather than the smaller-bodied strut fitted to lower-powered A-Class variants. Confirm your car is the 4WD A35 before ordering, since the multi-link rear and 4Matic subframe mounting differ from the standard front-drive A-Class.
