Setting up a brake system is actually a complex engineering problem. Many bracket racers approach it by randomly buying parts out of a catalog and then they have issues. There is a lot more stuff written on how to pick a cam than there is on how to pick a brake system which is probably a mistake.

For starters the fronts usually do twice the work of the rears so you need twice as much brake force up front as at the rear. That means the front pistons need to be twice the area of the rear pistons if the rotors are the same diameter.

If the front tire is too small to handle the brake force then you end up with a different problem. Trying to stop the car with the rear brakes is very tricky. The car is a lot more stable if most of the brake force is coming from the front tires.

Killing front rotors sounds like a pad issue to me but maybe the rotors are undersize. You might not have a brake balance problem, you might just have a component issue.

The best way to debug brake problems is to put a pressure gauge in both the front and the rear brake lines. Once you know what the pressure is in the lines then you can debug the rest of the issue. For really tricky problems you can use a heat gun or temp paint to figure out if the rotors are overheating.
