Two things:
1. Many think that braking hard, as late as possible is faster than braking less a little sooner. Just think about it.......... when you brake hard, you shift the weight of the car forward, thus making the rear light (whoboly and loose). Try to brake a little bit less (pressure) and earlier into the turn. You will achieve 2 things, a little higher corner entry speed and probably NO looseness in the rear.
2. I believe that 41 lbs. in the rear is too high. For street tires, I recommend 2 lbs. less at the rear than the front where the engine is. If you really want to maximize the alignment and tire pressures, keep accurate records at every event using a tire pyrometer. If you learn to interpret the results of this tool, you will maximize the grip any tire you use.
Obviously, Porsche made these car quite well and adjusted the design of their suspension based on their factory test drivers, so maybe your driving style should be modified somewhat as I said in part 1.
