XYZ Racing Street Advanced Coilovers — Mercedes-Benz SLK R170 4/6 CYL 1996-2004

The R170 SLK was tuned from the factory as a boulevard roadster first, sports car second, and its standard damping shows it the moment the road gets interesting. Body control loosens over mid-corner bumps and the nose dives under braking in a way that undermines the chassis this generation actually has underneath it. Street Advanced coilovers for the SLK R170 replace that softness with 720-way adjustable damping, giving the car a firmer, more resolved feel without turning it into something you dread driving to the shops.

This is XYZ Racing’s most-specified kit for exactly this kind of car: a road-focused roadster that still sees the occasional track day. It’s built for owners who want the SLK to change direction with less roll and settle faster after a bump, while keeping the ride civil enough for everyday use.

What this coilover does for your 1996-2004 Mercedes Benz SLK R170

Dropping the ride height and adding proper adjustable damping tightens up the vague, sofa-like responses that come with an ageing R170 suspension setup. The 720-way damping adjustment means you can run the car noticeably firmer for a spirited back-road drive or a track day, then wind it back for a comfortable motorway run home, all through the same kit. Lowering the centre of gravity reduces the nose-dive and squat that make the SLK feel heavier than it is under hard use, and sharper turn-in response follows directly from the reduced body roll. For a car whose factory dampers are now decades old on most surviving R170s, this is a straightforward way to get contemporary control back into a platform that still has good bones.

About the Street Advanced coilover

Street Advanced sits at the centre of XYZ Racing’s range, developed and refined over years of production and proven across race series worldwide before being brought back into a road-usable format. It’s built specifically to cover both everyday road use and occasional track days without asking the owner to compromise on one to get the other. The headline spec is 720 damping adjustment positions, giving a wide enough window to move between a comfortable daily setting and a firmer track-oriented one without swapping hardware. XYZ positions this kit as core equipment for drivers who want genuine control over how the car behaves, not just a lowered ride height with no adjustability behind it. For the SLK specifically, that range of adjustment matters because the car’s usage pattern tends to swing between commuting and quick weekend blasts, and the kit is built to serve both.
