The car only has 3000 miles on it and for that to happen this soon is pretty ridiculous.

I call BS. I've never seen stress fractures in iron discs unless they are cheapo drilled units.
Your tire guy is probably not a brake guy and mistook pad lining deposit lines for cracks. I've seen those.
Also all street brakes (and racing brakes for that matter) are front biased because of weight transfer effects. Front brakes do up to 80% of all braking.
The rear brakes on our BRZ are only 4 mm smaller in diameter and vented just like the fronts. They are 6 mm thinner so that they will heat up at relatively the same rate as the fronts.
