XYZ Racing Super Sport Coilovers — Holden COMMODORE SEDAN 1999-2006

The VT-to-VZ Commodore sedan is a heavy rear-driver that was set up for highway loping rather than B-road precision, and the standard dampers run out of body control long before the chassis runs out of grip. The XYZ Racing Super Sport coilover for the Holden Commodore sedan addresses exactly that – giving you a fully height-adjustable platform with 36-way damping so the live-axle (VT/VX) and IRS (VY/VZ) cars can be set up to suit your roads rather than the ones GM-H assumed you lived on.

This is the fast-road-with-weekend-track spec in the XYZ range. It accepts the Commodore’s mass, the long wheelbase and the front-end weight bias of the Buick-derived V6 and the 5.7 LS1, then lets you tune the rebound and compression in a single sweep until the car settles instead of floating.

What this coilover does for your 1999-2006 Holden Commodore Sedan

Drop the ride height to a sensible road setting and the Commodore stops looking like a 4×4 with the wheels tucked away in the arches – but more importantly it stops behaving like one. Body roll through faster sweepers reduces, the front end loads more predictably under trail-braking, and the rear stops the float-and-recover motion that plagues stock VT/VX dampers on undulating UK B-roads. The 36-way damping range matters here because the Commodore is heavy enough that you genuinely feel each click – softer settings keep it civil on broken tarmac with a passenger and a boot full of gear, stiffer settings tighten it up for a Sunday at Castle Combe or Mallory. The height adjustment is independent of spring preload, so you can sit it where you want it without binding the springs or compromising travel.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road damper, engineered to take the harshness out of bumps and rough surfaces while still giving you the adjustability of a proper performance coilover. Construction centres on a high-pressure damper body paired with height-adjustable lower mounts, so you set ride height by the body rather than by spring preload. The 36-way damping dial controls rebound and compression together in a single sweep – one knob, predictable behaviour, easy to learn. XYZ position this damper as suitable for both weekend track use and daily driving, which is precisely the brief most Commodore owners in the UK actually have: a heavy saloon that needs to feel alive on the way to the circuit and forgiving on the way home. Spring rates are matched to the chassis weight at the factory, so it arrives set up for the car rather than as a generic kit.

Fitment for the Holden Commodore Sedan (1999-2006)

This kit is built for the Holden Commodore sedan, chassis code HO01, covering the 1999 to 2006 production span. That envelope takes in the VT Series II, VX, VY and VZ sedans. Confirm your exact body style and front strut configuration before ordering if your car has been previously modified.
