XYZ Racing Street Advanced Coilovers — Cadillac CTS I 2003-2007

The first-generation CTS was GM’s bid to build a rear-drive sport saloon that could trade blows with Munich, and on its Sigma platform it had the bones to do it – but the factory damping left a lot of vertical travel and a soft, roll-prone front end that blunted the chassis on a give-and-take road. The XYZ Racing Street Advanced coilover for the Cadillac CTS I (2003-2007) is the kit that finally lets that platform sit and steer the way the engineering always promised.

This is the road-biased option in the XYZ range, built for owners who drive their CTS daily but want the body control to back up the occasional track day. Ride height comes down, the nose stops diving under braking, and 720 ways of damping adjustment let you set the car up for British B-roads without turning it into a kidney-punch.

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

Drop the front of a Sigma-platform CTS onto a properly valved coilover and the change is immediate: the slow, floaty weight transfer that defined the standard car gives way to a flatter, more deliberate turn-in. With 720 damping settings you can run a softer bump setting for broken tarmac and still keep the rebound tight enough to stop the rear axle pattering mid-corner. Lowering the centre of gravity tucks the wheels into the arches for a stance that suits the CTS’s angular bodywork, and the reduced dive under braking gives you cleaner, more confident stops into a corner. For a heavy-nosed rear-drive saloon, that front-end discipline is what turns the CTS from comfortable cruiser into something you genuinely want to lean on.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely sold coilover, refined over years of development by the company’s engineering team and validated through international race programmes before reaching production. It is set up specifically for the dual life of road use and the occasional track day, rather than committing fully to one or the other. The headline feature is the 720-way damping adjuster, which combines bump and rebound control into a single accessible range so you can move from a compliant road tune to a firmer circuit setting without changing parts. Ride-height adjustment is independent of damper stroke, so you keep usable travel even when the car is dropped. For CTS owners who want a measurable lift in control without surrendering everyday driveability, this is the series XYZ points them toward first.
