Has any one else experienced this on track? It was bad enough that it worries me that I may have a serious problem on the street in a panic stop situation.

Your fronts should lock up prior to the rears. If the rears are locking up first and you have the same compound pads on both the front and the rear you have an issue with your braking system and should have it looked at.
Just adding a proportioning valve to the rears to limit their bite will only reduce the braking ability of the rears and this will resolve the rear locking up first part, but it will increase peddle pressure to stop the car and I am convinced you have an issue with the fronts.
