XYZ Racing Super Sport Coilovers — Maserati Quattroporte M139 (Cancellation Kit for Electronic Damping) 2003-2012

The M139 Quattroporte was built around Skyhook adaptive damping, and when those original units fail the bill from a main dealer is enough to write the car off on paper. This XYZ Racing Super Sport kit for the 2003-2012 Quattroporte ships with the electronic damping cancellation hardware needed to bypass the factory Skyhook ECU cleanly, so the car stops throwing suspension faults the moment you turn the key.

For a 1,930kg saloon carrying a front-mounted Ferrari-derived V8, the Super Sport is the right pick: a fast-road coilover with enough range to settle the nose under braking and stop the rear squatting under throttle, without turning a GT saloon into a track car it was never meant to be.

What this coilover does for your 2003-2012 Maserati Quattroporte M139 (Cancellation Kit for Electronic Damping)

The M139’s biggest dynamic problem on tired Skyhook is vertical float over motorway expansion joints and a vague turn-in that betrays the long wheelbase. Swapping to a fixed-damping coilover with 30-level adjustment lets you tighten body control without making the cabin unliveable on UK B-roads. Ride height adjustment via the lower bracket – rather than spring preload – means you can drop the car to close the arch gap without losing usable spring travel, which matters on a car this heavy. Pillowball top mounts sharpen steering response at the front axle, and the included cancellation harness keeps the dash clean of suspension warning lights.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road and occasional-track platform, built on a 52mm monotube damper body with a separate spring perch and lower bracket for independent height and preload control. Damping is adjustable across 30 clicks on a single knob that controls both bump and rebound together, which keeps setup straightforward for owners who don’t want to live in a setup spreadsheet. Spring rates are matched to chassis weight and intended use, with linear-rate springs front and rear. The Maserati-specific kit adds the cancellation module that tells the factory ECU the original electronic struts are still healthy, so no dashboard errors, no limp mode, no recurring fault codes.

Fitment for the Maserati Quattroporte (2003-2012)

This kit fits the M139-generation Quattroporte (chassis code MS04-C in XYZ’s catalogue) built between 2003 and 2012, and it is the specific variant supplied with the electronic damping cancellation kit for cars originally fitted with Skyhook adaptive suspension. Confirm your car left the factory with the adaptive system before ordering – non-Skyhook M139s take a different part number.
