XYZ Racing Street Advanced Coilovers — Mercedes-Benz A CLASS W177 φ53 (Rear Twist- beam Suspension) 2018-2026

The W177 A-Class rides on a torsion-beam rear axle, which means the rear end’s behaviour is set almost entirely by spring and damper tuning rather than any multi-link geometry trickery. That makes the coilover doing double duty here – controlling ride height and controlling how the rear settles into a corner – more important on this chassis than on a car with independent rear suspension. XYZ Racing’s Street Advanced kit is built for exactly this kind of car: one that gets driven hard on a B-road at the weekend and still has to cope with a daily commute during the week.

For the A-Class, that means dialling out the slightly soft factory ride height without turning the twist-beam into a jittery mess over broken tarmac. Street Advanced gives you the range to lower the car properly and firm up the responses without giving up the compliance a torsion-beam rear axle needs to stay composed.

What this coilover does for your 2018-2026 Mercedes Benz A Class

Fitted to a 2018-2026 A-Class, this kit lowers the centre of gravity and reduces the body roll that the factory setup allows for comfort, sharpening turn-in without making the twist-beam feel unsettled on uneven surfaces. The 720-way damping adjustment lets you set the front and rear independently, which matters on a torsion-beam car where rear damping has to compensate for the coupled axle rather than working with a fully independent link. Run it softer for the commute and firm it up for a spirited drive without swapping parts. Ride height is adjustable independently of spring preload, so you can get the stance and the handling balance right without compromising one for the other. The result is an A-Class that turns in more directly and holds its line better under trail-braking, while still absorbing the daily grind of UK roads.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s volume seller, developed over several seasons of production and refined through use in the marque’s motorsport programme before being brought down to road-legal spec. It sits between comfort-focused OE-replacement dampers and full track kits, aimed squarely at drivers who use their car on the road but want proper adjustability rather than a fixed compromise. The headline figure is 720 damping settings, giving a genuinely wide window between plush and firm rather than the handful of clicks you get on cheaper adjustable dampers. Construction favours durability for road use – this is a kit meant to be lived with, not stripped down after every track outing – while still giving owners enough range to set the car up properly for a track day if they want one. It’s the kit XYZ positions as essential equipment for anyone who wants their car to go and handle with more intent than the factory setup allows, without asking them to live with a harsh ride the rest of the time.

Fitment for the Mercedes Benz A Class W177 (2018-2026)

This kit is built specifically for the W177-generation A-Class fitted with the torsion-beam (twist-beam) rear suspension, chassis code ME53, covering model years 2018 to 2026. Because the damper and spring calibration accounts for the twist-beam’s fixed-axle behaviour, this is not a generic multi-link kit adapted to fit – check your rear suspension type against the W177’s trim listings before ordering if you’re unsure which variant you have.
