XYZ Racing Super Sport Coilovers — BMW Z4 6 CYL (NON 3.2) 2002-2008

The Z4 E85/E86’s short wheelbase and rearward weight bias make it one of the more lively-feeling BMW roadsters and coupes to push hard, especially once the factory dampers start to fade under repeated direction changes. The XYZ Racing Super Sport coilover kit for the Bmw Z4 6 CYL (NON 3.2) (2002-2008) replaces that ageing damping with a fully height-adjustable, 36-way system built for fast-road driving and weekend track days.

It’s aimed at owners who want more control over how the car settles mid-corner and how it transfers load under braking, without turning the Z4 into something uncomfortable to drive to the circuit. Ride height and damping are both in your hands, so the same set of coilovers can be set up firm for a track session on Saturday and softened off for the drive home.

What this coilover does for your 2002-2008 Bmw Z4 6 CYL (NON 3.2)

On a car this light at the front and this eager at the rear, damping control matters more than outright spring rate. The 36-way adjustment lets you firm up compression to check the nose-dive under braking into a hairpin, then back off rebound so the rear axle doesn’t skip over broken tarmac on a B-road. Height adjustment brings the centre of gravity down, which tightens the Z4’s already sharp turn-in and reduces the roll that catches drivers out mid-corner. Because ride height and damping are independent of each other, you can drop the stance for a lower roll centre without stiffening the car into something that shakes over expansion joints on the way to a track day. The result is a Z4 that changes direction with less lag between input and response, and holds its line through a fast sweeper instead of wallowing into the outside kerb.

About the Super Sport coilover

XYZ Racing built the Super Sport line to deal with two things that wear a driver down on a fast road car: harshness over poor surfaces, and a fixed ride height that can’t be matched to changing conditions. The damper offers 36 stages of adjustment, so compression and rebound can be tuned from a comfortable fast-road setting through to a firmer track configuration without changing parts. Ride height adjustment is built into the same assembly, which lets you correct stance and corner weights once the springs have settled on the car. XYZ positions the Super Sport as a kit that covers both ends of the same car’s life – a daily commute and a weekend circuit outing – rather than forcing owners to pick one or the other. On the Z4’s relatively short, stiff platform, that adjustability matters more than it would on a softer car, because small changes in damping show up immediately in how the rear axle behaves over mid-corner bumps.
