The Agency Power x Swift Springs Lowering Springs for the McLaren 12C and 650S are a great way to achieve a better stance.  The installation is not a simply DIY and we HIGHLY recommend having a qualified dealer or tuning shop do the installation.  Because the McLaren 12C or 650S runs a hydraulic suspension system, it is imperative that you do not disconnect these lines to remove the shocks.  If you do this will result in very expensive service at McLaren.  Installation is not sold so anything you do is at your own risk.  For those that do want to tackle this project, we have some installation steps below.  Besides standard tools, a set of spring compressors is required.  Once the springs are installed, you WILL need to get an alignment done.

Rear Spring Installation – This requires removal of more parts to get access to the rear shock.
