XYZ Racing Racing Spec Coilovers — Porsche 997 TURBO CARRERA-4 (Cancellation Kit for Electronic Damping) 2005-2011

Porsche’s PASM system was developed around road use, and it shows on circuit. The adaptive logic reads transient events and chases them – a speed bump, a sudden lane change, the initial jolt of braking. Feed it the sustained lateral loads and repeated braking zones of a track day, and it keeps adjusting, never settling on the position the driver has chosen. For 997 Turbo Carrera-4 owners committed to serious circuit work, that inability to hold a consistent damper position is the primary suspension problem.

The XYZ Racing Racing Spec coilover for the Porsche 997 Turbo Carrera-4 replaces the PASM units entirely, pairing a mechanical, manually adjustable damper with the cancellation harness that satisfies the ECU. The kit is calibrated to the specific dynamics of this AWD platform – the rear-engine weight bias of the 911 chassis, the front-axle inertial loads under hard braking, and the lateral forces this car’s mass and twin-turbo output place on the suspension through sustained high-speed corners.

What this coilover does for your 2005-2011 Porsche 997 TURBO CARRERA-4 (Cancellation Kit for Electronic Damping)

Removing PASM from the equation gives the driver something the factory system cannot provide: a damper that holds exactly what is set. The rear-engine 911 architecture’s pendulum dynamics respond predictably when suspension inputs are consistent, and the Racing Spec units are rated for the brake-to-apex loads that the Turbo Carrera-4’s four-wheel traction and twin-turbo output demand. Lowering the 997 Turbo shifts its centre of gravity incrementally, reducing the pitch sensitivity that the rear-engine layout amplifies at the limit. With damping and ride height set to the circuit, the AWD torque distribution works with the chassis rather than against it.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s dedicated circuit and time-attack coilover, with damper settings derived from direct participation in WTCC race events – not from road-based development or simulation data. Every adjustment position was obtained under actual race conditions, a meaningful distinction when the suspension must handle the same high-load, high-repetition demands a race weekend generates. For 997 Turbo builds carrying significant upgrades beyond standard specification – uprated brakes, aggressive aero, power modifications approaching A-class levels – XYZ Racing offers custom-built damper units to individual order. Provide details on the modified components in your car and the circuits you intend to run, and the engineering team configures the shock absorbers to that specific brief.

Fitment for the Porsche 997 TURBO CARRERA-4 (Cancellation Kit for Electronic Damping) (2005-2011)

This kit covers the Porsche 997 Turbo Carrera-4 under chassis reference PO04-2-C, spanning the 2005 to 2011 model years. It is a cancellation-kit specification, meaning it includes the components needed to replace and electrically satisfy the PASM electronic damping system. Confirm your car is PASM-equipped before ordering – the standard 997 Turbo without PASM requires a different specification.
