XYZ Racing Super Sport Coilovers — Citroen C4 2004-2010

The C4 was never sold as a driver’s car, but the chassis underneath – shared in part with the Peugeot 307 and stretched to carry a longer wheelbase – has more in it than the factory soft-spring tune ever let on. Drop the ride height, control the body roll the standard dampers wave through, and the C4 starts behaving like the hatchback PSA could have built if the brief had been different.

The XYZ Racing Super Sport coilover is the right answer for owners who use a C4 daily but want the option of a weekend B-road blast or the occasional track day without owning two sets of suspension. Height-adjustable, 36-way damping, and tuned to handle UK road surfaces that punish anything set up purely for the circuit.

What this coilover does for your 2004-2010 Citroen C4

The standard C4 setup leans into corners, runs out of damper travel on mid-corner bumps, and dives under braking in a way that masks how much front-end grip is actually available. Replace it with the Super Sport and the nose stays composed under trail braking, the rear follows the line you’ve asked for rather than shuffling sideways over expansion joints, and the whole car feels a size smaller. 36-way damping means you can run the front softer than the rear for daily commuting and stiffen both ends up before a track session without touching the ride height. The lowered stance fills the arches properly – the C4 wears its standard ride height badly – and the spring rates are picked to hold composure over British B-road surfaces rather than glassy circuit tarmac.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road damper, engineered specifically to take the discomfort out of bumps and rough surfaces while keeping enough body control for circuit work. Construction is height-adjustable with 36 clicks of compression-and-rebound damping on a single knob per corner, so dialling in the balance between a comfortable daily setting and a sharper weekend setup is a thirty-second job at each wheel. The spring and valving combination is selected so the same kit covers everyday road conditions and the occasional track session without needing a re-valve. It sits in the XYZ range above the entry tier and below the dedicated circuit dampers – the part for owners who want a single suspension setup that works for both how they use the car Monday to Friday and how they want it to behave on Sunday.

Fitment for the Citroen C4 (2004-2010)

This kit is built for the first-generation Citroen C4 hatchback and coupe, chassis code CI03, covering production years 2004 through 2010. Spring rates, damper lengths, and top-mount hardware are matched to the CI03 platform.
