Further Evaluation:  I would plan a drive through Central Nevada and Death and Panamint Valleys on those nasty old narrow 2 lanes where the 996 GT2 tram lined and hunted so bad, you had to slow below 150 to stay between the white lines. It would bottom out and scrape in the drainage dips.

The GT2RS on the same  roads would not bottom out as it had a depth of sequential stiffness that only came into play and your cognition when you were deep in compression in a drainage ditch hollow at very high speed - I believe it unlikely the SF suspension is anywhere near as sophisticated, so you'd battle for control but no way to know without running the route.  I could be positively surprised that the everyday stiffness is perfect for those vicious dips at high speed.

 I would switch to Michelin PS 4S for this test, and run 29/28 psi.
