Step 1: Preparing lower chassis.

The MR B3RB car should look like this in the pre-production unit after opening the box.

Adding front and side covers

UPDATING: The production units will instead include the larger side plastic skirts. The small plastic clips shown below will not be used. It will no longer be required to replace the top plate screws and clips.

Remove top plate screws and clips

Use a hex screwdriver or Allen Key and remove all top and side screws securing the top plate to the metal frame and carefully set them aside. These screws are important for later steps when you'll need to reattach the metal frame.

After removing the screws, carefully detach the eight plastic holders from the side. Remember to keep the screws and nuts in a safe place, as they will be needed later.
