Playing with some more numbers and thinking of the issue with a 930 squatting from so much HP I have come up with a set up that might be interesting.

In the rear one could run 33mm rear torsion bars with no sway. This would be equal in spring rate to about a 30 to 31 mm rear torsion bar and stock sway bar combination but would be 30% stiffer in squat. It is also about 140% stiffer in squat than stock over a stock 26mm 930 rear torsion bar.

In the front one could run 22mm torsion bars with an adjustable aftermarket sway bar. This will stiffen up the front's lift under acceleration about 125% and allow for tunning of the front to rear balance.

Again, such a set up should run about like a 22/30 or 22/31 with sways but have less squat.

Further it would squat about 10-12% less than adding 300# helpers to the rear but should handle much better.
