XYZ Racing Drag Racing Coilovers — Citroen C4 2004-2010

The first-generation Citroen C4 left the factory tuned for ride comfort, riding on soft springs and a long-travel front end that squats and pitches the instant you load the driven axle. For a standing start that softness is wasted energy: weight rolls around the body instead of pressing the front tyres into the tarmac. The XYZ Racing Drag Racing coilover for the Citroen C4 (2004-2010) exists to deal with exactly that.

This is a kit built around the 0-400 metre run rather than the B-road. It governs how the CI03 chassis shifts its mass off the line, planting the driven tyres hard at the hit and holding the car steady as speed climbs toward the traps.

What these coilovers do for your 2004-2010 Citroen C4

Fit these to your 2004-2010 Citroen C4 and the first thing you feel is a launch that bites instead of scrabbles. By managing weight transfer onto the front, driven wheels at the moment of the hit, the coilovers force more compression into the contact patch and cut the wheelspin that quietly bleeds away a quarter-mile time. Height adjustment lets you set a rake and ride height to suit your tyre and the strip surface. Firmer, controlled damping stops the nose diving and the tail floating as the C4 gathers pace, so it tracks straight rather than wandering as you change up. The pay-off is a more repeatable sixty-foot and a car that feels settled at the top end.

About the Drag Racing coilover

XYZ Racing builds the Drag Racing coilover specifically for 0-400 metre work, and the same platform is engineered to suit front-, rear- and four-wheel-drive cars. The core idea is deliberate weight management: the spring and valving setup let the car move its load front-to-rear in the instant of launch, throwing mass onto whichever axle is putting the power down. On a front-driven C4 that means loading the front tyres so they compress harder against the surface, which shortens the period of wheelspin and gets the car hooked up sooner. That same control then earns its keep at high speed, keeping the body stable as the run develops instead of letting a soft chassis pitch and squirm. It is a focused, single-purpose tool: a coilover aimed at consistent launches and straight-line stability, not at lap times or fast-road ride quality.

Fitment for the Citroen C4 (2004-2010)

This kit is matched to the first-generation Citroen C4, chassis code CI03, across the full 2004 to 2010 production span. It is cut for that platform’s mounting points and geometry, so confirm your car’s build year falls inside that range before you configure. No other trim-specific data is listed here; if you are unsure, check against your chassis code.
