You're on it. The front should have about 65% of your braking force on tarmac. That is acheived by a balance bar on dual master systems but you should get close with your hydraulic sizes first and adjust from there. The brakes should be sized to favor the front more (say 70%) if there's a choice. Race cars dealing with changing track conditions, weights of fuel etc have variable adjustment built into the car. You can also shut down the rear brakes with a bias valve but why reduce the force when you can mechanically dial it really close and use all your braking force.
