XYZ Racing Tarmac Rally Coilovers — Cadillac CTS I 2003-2007

The first-generation Cadillac CTS is an awkward beast to set up for stage work. Sigma-platform underpinnings, a long bonnet over the 3.2 or 3.6 V6, and a kerb weight knocking on 1,700kg mean the standard car runs out of body control long before it runs out of grip. The Tarmac Rally coilover is built for exactly that mismatch – a heavy, rear-drive saloon being pushed hard down a sealed special stage where the surface keeps changing under you.

XYZ Racing developed this damper for crews running tarmac events where the road is fast but rarely smooth. On a CA01 CTS that means controlling the nose dive into a hairpin without losing the compliance that lets the inside-rear stay loaded over a mid-corner crest.

What this coilover does for your 2003-2007 Cadillac CTS I

The Tarmac Rally damping curve is tuned to absorb sharp vertical inputs – kerbs, ruts, broken edges – without the rebound becoming wooden afterwards. On a CTS that translates into a front axle that stops washing wide every time the road surface changes mid-corner. Body roll is reined in enough that the long wheelbase stops feeling like it is fighting you, and the rear axle starts placing power down through the diff instead of skipping over compressions. Ride height and damping are both adjustable, so you can run the car low enough to take weight out of the nose without losing the suspension travel a heavy V6 saloon genuinely needs.

About the Tarmac Rally coilover

This is XYZ Racing’s purpose-tuned damper for sealed-stage tarmac rally use, with all settings drawn from the brand’s own tarmac competition programme. The design priority is impact absorption – swallowing the jolt from a big bump without unsettling the body or breaking traction at the tyre. Damping is calibrated to suppress shock through the chassis on uneven pavement while keeping the contact patch loaded, which is what gives the car its stability when the road camber is working against you. The construction targets repeat punishment from a stage car rather than the lighter duty cycle of a circuit setup, and the adjustment range is wide enough to suit different rally surfaces from smooth twisty sections to rougher mountain tarmac. Spring and damper rates are matched to the use case rather than to a generic road-car compromise.
