Frankly most of the faster 911's I've seen do this... And to second someones notion, If you look at pics of many old porsches, they show this phenomenon...
If you ask me, it's a badge of honor, shows you're cornering well... The faster I get, the more that wheel comes up. There's a guy racing a lotus in VSCDA with me that is REALLY fast, his inside front comes up 6" in turn 3 at Road America. Yes, it means your rear anti-rolls are softer, and the fronts are harder, but I think this is a good thing, as this a way you can dial in a bit of understeer to a 911.

Jack,
I would also say that your front torsion bar may be a bit soft compared to the rear. I run 22/28. The wheel lifting though is more due to chassis stiffness and anti-roll bars I think. Flex CAN actually be good, like in the rain... The fastest rain race I ever ran was in a 911 that flexed quite a bit. Finished 30 seconds faster than the next cars...

Jack,
Nice "up on 3" pics! I would only play around with the sway bars and T-bar settings if the car isn't handling to your expectations, or if you just want to experiment with different set-ups, but I wouldn't do it seeking constant 4-wheel contact. My theory is that if all four wheels are on the ground 100% of the time, you are not going fast enough!  If you watch any of the ALMS or Rolex Series races, you will notice that even the new generation 996 race cars will occasionally be up on 3. Good stuff!
