Smaller always goes on the back. Once you get the wheels off you will know.

Every car is that way. Fronts do the majority of the work and therefore need the bulk of the material. The rears are more or less there to "balance" every thing out and keep the rear from swinging around really.

Look at my pic of the Caddy in my sig. Note the size of the caliper in the front vs. the back.
