XYZ Racing Super Sport Coilovers — BMW Z4 6 CYL (NON 3.2) 2009-2016

The E89 Z4’s retractable hardtop tucks away neatly, but it adds real weight up high and well behind the rear axle, weight the factory dampers were tuned to absorb rather than properly control. On the six-cylinder cars this NON 3.2 fitment covers – the 30i, 35i and 35is – that extra mass shows up as float over broken B-road surfaces and a rear end that’s slow to settle once you’ve turned in. XYZ Racing’s Super Sport coilover is built for fast-road and weekend track use, giving the chassis a proper way to manage that weight instead of just soaking it up.

It’s a full coilover kit, so ride height and damping are both adjustable rather than fixed to whatever compromise BMW signed off on across four different engine outputs. For a Z4 doing commuting miles most of the week and a track day or two a year, that adjustment range matters more than outright stiffness.

What this coilover does for your 2009-2016 Bmw Z4 6 CYL (NON 3.2)

Dropping the ride height and firming the spring rate over standard pulls the Z4’s centre of gravity down, which matters more here than on a hatchback because the folding roof mechanism sits so high and so far back. The 36-way damping adjustment lets you back the compression off for the drive to work and wind it up for a trackday without swapping parts, useful on a car where the factory setup is one fixed compromise for every 30i, 35i and 35is variant. You’ll feel the difference most under trail braking into a corner, where the rear axle stops pitching and starts loading evenly, and through fast direction changes where the hardtop’s mass no longer arrives a half-beat late. Ride height adjustment also lets you correct the nose-up stance the factory setting leaves on six-cylinder cars carrying the heavier engine and the retractable roof mechanism.

About the Super Sport coilover

Super Sport sits in XYZ Racing’s range as the fast-road-and-track option, built to take the harshness out of the ride you’d otherwise get from a hard, fixed-rate spring without giving up body control when you lean on it. The damper carries 36 discrete clicks of adjustment, enough range to move from a setting that copes comfortably with UK road surfaces up to one that holds the car flat through a fast direction change on circuit. Ride height is independently adjustable on the strut, so stance and corner weights can be set without touching the damping curve, and vice versa. XYZ Racing positions this kit for owners who need one car to do both jobs – a daily driver during the week and a weekend circuit car – rather than committing to a single-purpose track setup that’s miserable on the road.

Fitment for the Bmw Z4 6 CYL (NON 3.2) (2009-2016)

This kit is built for the E89-generation Z4’s six-cylinder models from 2009 to 2016, specifically cars fitted with the 30i, 35i and 35is engines rather than the earlier 3.2-litre unit. Chassis code BM74-1 covers the front and rear strut mounting points and spring perches for this fitment.
