Darren, I drove another person's 996 at Pocono South last year with PSM and I could get the car to oversteer. Even left foot braking through hair pin and entry off the bowl. The key is the throttle overlap had to be very brief. Car would pitch just right off the bowl. Hairpin, everyone could use more turn in, but still did not plow. I think you have too much tire up front with 265's from your prior setup. MPSC's just don't get hot enough with that much rubber up front. You need 160 deg of tire temp for real grip with MPSC's. Maybe with your new suspension addtions you will get the added heat. I guess we will find out next weekend.

It may be too much tire, have to experiment though Hopefully I get it back together in time for Shenandoah. The problem I'm running into is the amount of lateral load transfer with the springs that I have. The extra grip is great, but I don't have the right suspension to make use of it. The tires end up rubbing (at the top) and I don't think I can stop it without bigger springs.
