XYZ Racing Top Sport Coilovers — Porsche 991 CARRERA-2/S/TURBO (without hydraulic lift system) (Cancellation Kit for Electronic Damping) 2011-2019

Managing the 991’s rear-biased weight distribution – roughly 57% over the back axle even before the Turbo adds 520bhp to the equation – is the foundational question in any suspension upgrade for these cars. The factory PASM system answers it with electronically controlled dampers operating across Normal and Sport modes, but those modes are calibrated for a broad range of use. The XYZ Racing Top Sport coilover for the Porsche 991 Carrera-2/S/Turbo is set tighter: damping and spring rates raised above the street baseline, the calibration drawn from track-day use rather than road-surface compromise, and the PASM cancellation kit included to keep the ECU from flagging what it no longer controls.

This kit is specified for 991s without the factory hydraulic front lift system, which alters strut geometry at the front axle when fitted. Confirm your car’s specification before ordering – it will be noted in the original factory documentation.

What this coilover does for your 2011-2019 Porsche 991 Carrera-2/S/Turbo

Damping set 30-50% above the PASM street-mode baseline gives both ends more authority over body movement, containing the pendulum effect of the 991’s rear mass through quick direction changes. The 2kg/mm spring rate increase above street specification reduces chassis pitch under braking and lateral roll through fast corners – on the rear-drive Carrera 2, that translates directly into more consistent traction on corner exit. Improved tyre contact patch consistency throughout means both ends deliver a clearer picture of available grip, which on a car with the 991’s weight rearward is what separates assured driving from tense driving. The same settings absorb road imperfections well enough for the run home after a track session.

About the Top Sport coilover

XYZ Racing’s Top Sport coilover series occupies the serious end of road-and-track use: not a comfort-biased sports setting, but calibrated specifically around track-day and aggressive road driving rather than outright competition-only performance. Damping rates run 30-50% above street specification, and spring rates are increased by 2kg/mm over a standard road setup, generating a firmer chassis platform that suppresses body movement and holds traction more consistently over uneven surfaces. The specification has been developed from XYZ Racing’s accumulated track-day experience, so the numbers reflect what actually works under load rather than theoretical optima. The 991 application covers the full Carrera range from 2011 through 2019 – encompassing the naturally aspirated 991.1 cars and the turbocharged 991.2 platform across Carrera-2, Carrera S, and Turbo variants.

Fitment for the Porsche 991 Carrera-2/S/Turbo (2011-2019)

Listed under chassis code PO31-C, this kit covers the Porsche 991 Carrera-2/S/Turbo from 2011 through to 2019, spanning both 991.1 and 991.2 generations. It is specified for cars without the factory hydraulic front lift system. The PASM cancellation hardware is included to manage the electronic damping monitoring that operates continuously in these cars.
