XYZ Racing Super Sport Coilovers — BMW Z4 M 2002-2008

The Z4 M’s S54-powered chassis was always a slightly awkward proposition from the factory – a short-wheelbase roadster (or coupe) sat on a suspension setup that struggled to reconcile the engine’s appetite for revs with the body’s tendency to pitch and squat under load. The Super Sport coilover for the Z4 M is built for owners who want to settle that chassis down without turning their weekend car into something punishing on the B-road home.

This is the fast-road and weekend-track-day spec in the XYZ Racing range. 36-way damping adjustment lets you run a softer setting for the broken Tarmac most UK owners actually drive on, then firm things up before a session at Cadwell or Castle Combe.

What this coilover does for your 2002-2008 Bmw Z4 M

Drop the Z4 M onto Super Sport and the first thing you’ll notice is the front end stops floating mid-corner – the S54 sits over the nose with real mass, and stiffer, height-adjustable damping pulls that weight under control before it loads up the outside front tyre. Turn-in tightens, the rear settles, and the car stops feeling like it’s working against you when you commit to a line.

Ride height adjustment lets you take the gawky factory wheel-arch gap out without going slammed, which matters on a roadster that already had a polarising stance. The 36 damping clicks give you a genuinely usable spread – one end of the range is liveable for a daily commute, the other is firm enough for a track-day setup. Braking confidence improves with the reduced dive, and on the coupe you’ll feel the rear axle plant earlier on corner exit when you’re back on the throttle.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road damper engineered to take the discomfort out of bumps and rough surfaces without losing the body control you bought a coilover kit for in the first place. Ride height is fully adjustable on the threaded body, and damping runs across 36 distinct settings on a single combined adjuster – one knob, top of the strut, no separate bump and rebound circuits to second-guess.

The brief from XYZ is explicit: a high-performance damper suitable for both weekend race use and daily driving. That dual remit is why the Super Sport sits where it does in the range – softer and more compliant than the track-focused Circuit Master options, firmer and more controlled than a standard OE-replacement coilover. Construction is the usual XYZ specification with serviceable internals, so the kit can be rebuilt rather than binned when the seals eventually give up. It’s the spec most Z4 M owners actually want once they stop reading forum threads about pure-track setups.
