XYZ Racing Street Advanced Coilovers — Mercedes-Benz ML/GLE CLASS W166 4WD 2011-2019

The W166’s air-suspension-replacing coilover conversion has to do two jobs the standard SUV owner never thinks about: keep a two-tonne-plus 4WD platform composed under its own mass, and still ride like something you’d choose to drive daily. The Street Advanced coilover for the ML/GLE Class W166 is built around that trade-off, giving the big Merc a lower, tauter stance without turning every speed bump into a complaint.

For an SUV this heavy, damping range matters more than outright stiffness. XYZ Racing’s Street Advanced platform carries 720 damping adjustment positions, so the compression and rebound curve can be set soft enough for the school run and firm enough to control body roll on a B-road, all from the same shock.

What this coilover does for your 2011-2019 Mercedes Benz ML/GLE Class W166 4WD

The W166’s factory air suspension is comfortable but vague at the limit, and a lot of owners replacing worn air struts want a setup that finally tells them what the front axle is doing under load. Switching to a coilover kit brings a fixed, adjustable spring rate that ties down the SUV’s high centre of gravity through direction changes, cutting the float and delayed recovery that air springs allow once you’re past a gentle cruise. The 720-way damping adjustment lets you firm up compression for a loaded boot or a motorway blast, then wind it back for broken urban tarmac, without swapping parts. Ride height is also adjustable independently of damping, so you can drop the W166’s stance to cut aero lift and improve the visual proportions that the factory air setup can’t touch at speed. On a 4WD platform carrying this much weight over the front axle, a properly damped coilover also reduces the nose-dive under braking that stock air suspension struggles to arrest smoothly.

About the Street Advanced coilover

XYZ Racing developed the Street Advanced line as its core product, refined over successive seasons of testing on the company’s own competition programme before the specification reached retail. It sits between a comfort-biased road kit and a dedicated circuit setup, aimed squarely at drivers who use their car every day but still want a suspension that responds properly when the road gets interesting. The 720-way damping adjustment is the headline figure, giving a far finer resolution of control than a basic 16 or 32-click shock, which matters when you’re trying to find one setting that works for both a laden motorway trip and a spirited backroad. Construction follows XYZ Racing’s monotube-style approach used across the range, chosen for consistent damping force under sustained heat cycling rather than the fade you get from cheaper twin-tube designs. It’s positioned as an everyday-usable kit with a genuine track-day ceiling, not a compromise product bolted together to hit a price point.
