Description

ST XA coilovers combine ride-height adjustment with adjustable rebound damping. Select the correct article for your vehicle, axle loads and factory suspension equipment using the application details below.
ST X or ST XA for your Porsche 987?
This ST XA 18271016 kit adds manually adjustable rebound damping to ride-height adjustment. Choose it if you want to tune the rebound setting. If you prefer factory-set damping, compare the ST X 13271016 kit for the listed Porsche 987 applications.
Will this kit retain Porsche PASM?
On a PASM-equipped car, the factory electronic damping must be deactivated as specified in the application notes and installation instructions below. The XA rebound adjuster is manual and does not retain PASM control. Confirm the required deactivation method and any additional hardware before ordering.
