The method Mike describes is the one I generally use. On most rear/mid engine Porsches, you will end up with 50.4% on the LR/RF diagonal. I consider this the most neutral method. Obviously, this will leave the opposite diagonal at 49.6% - 0.8% different from the other diagonal, which is a compromise from the 50% diagonal "ideal." The compromise with the 50% diagonal on most production based cars is going to be front weights that are statically not equal - that is going to be a compromise under braking. If you match the front wheel weights statically, you will have corner balance around 51%.
As long as the LR/RF diagonal is between 50.0-51.0%, it will be fine in almost any situation. None of this considers track related tuning - "wedge" in the oval world.
The necessity to compromise comes from the fact that 911 and boxster based cars are not equal front/rear or left/right. Meaning, no matter what you do with corner weights, you can never change the left/right or front/rear weight bias.

The set up also will change for different tracks and driving styles. not a one size fits all discussion
you cant significatly change front to rear, or side to side proportions with ride height. however, you always can fix cross weights with ride height , however there are limits with doing so.
