XYZ Racing Circuit Master Coilovers — Porsche 997 CARRERA-2/S (Cancellation Kit for Electronic Damping) 2005-2011

Deleting PASM on a 997 Carrera is a deliberate commitment – you are trading the road-car versatility of Porsche’s Active Suspension Management for a fixed, fully adjustable platform you can actually set up around a specific circuit. The Circuit Master coilover for the Porsche 997 Carrera-2/S (2005-2011) ships with the PASM cancellation kit included, giving you a clean break from the factory variable-damping architecture and a foundation calibrated for sustained circuit lap-time work.

The 997’s rear-engined layout makes suspension choices more consequential than on a front- or mid-engined car. Too stiff at the rear and the car’s natural rotation tendency becomes a liability; too little front compliance and the nose runs wide under load. With 9,720 adjustment combinations across three damping knobs, the Circuit Master gives you the resolution to address those trade-offs directly rather than accepting the factory’s road-biased compromise.

What this coilover does for your 2005-2011 Porsche 997 Carrera-2/S

The most significant change after installation is damper consistency – with PASM removed from the system, response is fixed and repeatable rather than varying with speed and load inputs as the factory electronics interpret them. The 997 Carrera-2’s rear-wheel-drive balance is already a strong starting point for circuit work; the Circuit Master allows you to tune how quickly the rear loads on corner exit and how the front behaves under trail-braking. Three distinct adjustment knobs govern separate aspects of damper behaviour, so you can work on high-speed compliance independently from low-speed kerb-ride response – a separation that matters when optimising for a specific track layout. The small oil-hole damper construction adds a further layer of control to the transition between fast and slow damping phases, giving the 997’s chassis a more graduated response to abrupt inputs.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s top-specification coilover, developed within the same product family as the Racing Spec, Drift Spec, and Tarmac Rally variants. The design has been validated by XYZ Racing teams across international circuits, and that development process shows in the specification: 9,720 distinct adjustment configurations are accessible through three knobs, giving competitors the granularity to optimise for different track surfaces, tyre compounds, and ambient conditions across a single race day. The damper uses a small oil-hole passage design that governs fluid behaviour through larger suspension events; this construction can produce minor noise over sharp impacts, which is an expected and normal characteristic of a component calibrated for smooth circuit surfaces rather than road use. The Circuit Master is not a crossover product – it is designed specifically for circuit use, where road-surface irregularities are not part of the engineering brief.

Fitment for the Porsche 997 Carrera-2/S (2005-2011)

This kit covers the Porsche 997 Carrera-2 and Carrera-2S (chassis code PO04-C) across the full 2005-2011 production run. The PASM cancellation hardware is included in this package, meaning buyers do not need to source that component separately before fitting the Circuit Master coilovers. If you are unsure whether your 997 carries the PASM option, check the build specification on the vehicle’s data tag or consult a Porsche specialist before ordering.
