You can't selectively disable one end of the ABS, it will get confused and you're likely to end up in a hedge somewhere. If you're set on removing ABS you'll have to remote the fronts as well. I'm unsure on the legality in your part of the world but here it's most definitely illegal to disable one of the most essential safety devices on the car.
Personally I think you're mad for wanting to get rid of it, ABS has saved my bacon several times in situations beyond my control.
