Don't worry about the brake discs. Won't hurt a thing.

Fuchs won't rust. If they do, they aren't Fuchs.

Remove the battery.

Put a couple old tupperware tubs of rock salt inside the trunk and floor of the car. Don't fill them full of salt. Maybe 1/2 full. The salt will absorb the moisture and keep the interior relatively dry. You may need to change the salt every few weeks or so. In Florida we used to put a frisbee full of salt on the floor to keep the interior from smelling musty.

Hopefully not an earth floor, although concrete is not a lot better.

How big is the garage? Small one-car? Can you cover the floor with plastic? Heavy plastic drop cloths from Home Depot? That would help a lot.
