The wheel has a bore in the middle that fits over the axle shaft in the center of the hub, this bore is called the Center Bore. There are different sizes of center bore, and they make an adaptor called a hub-centric ring that fills the space between the hub and the sides of the bore hole.
If the bore hole is 76mm, and the hub is 72mm, then there is 4mm (2mm all of the way around) that has to be properly centered. If you do not have the hub-centric ring, then the wheel can be mounted off center on the hub and this will translate into a shaking that feels like an out of balance tire, although all tires will balance perfectly.
A spacer is used to move the tire (wheel) outboard so that it does not collide with the undercarriage components. If the car calls for a rim with back spacing (offset) of 25mm, and you find a package that has backspacing of 50mm, then you would need a spacer to pull the wheel away from the suspension. Back spacing, or offset, is the distance of the mounting surface on the back of the wheel to the centerline of the wheel. If this distance goes down, then the wheel is moved outboard toward the fenders. If the distance goes up then the wheel moves inboard toward the suspension. A caveat is that when the rim gets wider AND the offset remains the same, the tire is still moved into the fender.
Find your tire/wheel package here and see if your car is listed as one of the models. If yes, then the package will fit without modification. If no, then modifications needed will vary depending on what the specs are of the package you are looking at. Sadly, the center bore specifications are not given.
