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

The W177 A35’s 4MATIC hardware piles extra mass low and rearward compared with the front-drive A-Class, and the factory suspension was tuned to mask that weight rather than exploit it. Trail-brake one into a damp roundabout and the standard dampers let the rear settle late, just as the Haldex clutch is trying to feed torque back to it. XYZ Racing’s Street Advanced coilover kit for this chassis gives that AWD driveline a suspension that keeps pace with it.

This is a road-and-occasional-track-day kit rather than a full circuit setup, so it favours a wide damping window over outright stiffness. That means real control on a fast A-road on Saturday and a suspension that still rides properly on the school run come Monday.

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

With 720 damping settings on tap, you can wind the rear firmer to settle body movement the moment the Haldex system starts shifting torque rearward out of a corner, then back it off again for a motorway cruise. The 55.5mm shock body gives the kit the bearing surface to resist flex under the A35’s cornering loads without the harshness of a smaller-bore unit. Ride height adjustment lets you correct the nose-down stance the AWD hardware and DCT gearbox add over the front axle, sharpening turn-in response. Because the rear mount is built to integrate with this chassis’s modified rear geometry, the extra unsprung mass back there gets properly located instead of just stiffened against.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s highest-volume line, refined over several years by the brand’s in-house engineering team and validated in international competition before reaching road cars. It is pitched at drivers who want one set of coilovers to cover normal road use and the odd track day, rather than choosing between comfort and capability. The 720-way damping adjustment is the headline spec: enough granularity to find a setting for a bumpy B-road, a smooth motorway, or a dry sprint circuit without swapping parts. XYZ position it as essential kit for anyone chasing genuine speed and control from their car, not just a ride-height drop.
