Driving a C4 Cab....vs a 76' 911S Targa

I have two Porsches, the 99' C4 being new to me this last spring. Of course, there's a world of difference between the two cars. Curiously, the steering on the C4 is heavier than the 911S, even though the C4 has power steering. The "heavy" feeling of the C4 seems to disappear at about 35mph. I'm aware of the tail-heavy problems of the 911s, and have learned the hard way to apply power thru a turn (to create oversteer, if I understand the terms right). And I've also learned that you don't apply brakes in a turn with the 911s. Unless it's your intention to spin it. But with the C4, I seem to not feel any of the usual "tail-heavy" issue that typically characterize 911's. Is it because I've never been near the limits of the C4? The Carrera simply slams you laterally in turns with no evidence of it ever coming loose. Is it the PSM? Should I turn it off to "learn" about the limits of the C4? Would like to hear from previous 2wd 911S owners who now have C4's....

I have a 99 C2 and I know from experience you can spin it. I turned in too soon on turn 7 at road atlanta and I could feel the rear coming around when I tried to keep it in the track. Very exciting. Fortunately, I didn't hit anything. I think the C4 would have similar dynamics. Never driven one of the old 911s, but I did go for a wild ride in a modified 914. The 914 did not give me much confidence. It was definitely lighter than the 996, but far more skittish, probably due to the skinny tires.

Porsche supposedly dialed out that crazy oversteer issue with the 993. The 996 is very stable. The rear end is still heavy, and it will come around, but not any more than any other car I�ve owned. In fact, my 06 M5 could break the tires loose a lot easier than my 996.
