The Akebono fixed 4-pot caliper and 14-in rotor require a minimum of 18" wheels, even then, not all 18" wheels would provide enough clearance radially, laterally, or both.
If I could say anything about tire set for autocrossing, I would suggest running scrubs in order to keep the street set in a nice condition. In case you didn't know, street tires used in autocross tend to become rougher in ride quality as edges are chewed up.
