Remove the two allen bolts that attach each motor mount to the frame of the car. They are 6mm allen head bolts.

The outboard ones, those furthest towards the outside of the car (both sides of the car shown), are best accessed from above with a 6mm allen socket and a very long extension or several shorter extensions.

The inboard ones, those closest to the engine, need to be removed from below the car with a 6mm allen key. These are difficult to see, much less take a picture of, but can be removed by feel fairly easily. They can be found almost directly below the metal arm that comes off the engine that attaches to the top of each mount.

Pictured are the bottoms of these two bolts. Inboard is shown highlighted in green, outboard in blue, to help show location from below the car.
