Avenged,
JonB is right, you
should not run old, worn out run flats on the front and new sticky tires on the back ..... especially if you're going to drive aggressively around a track or around town for that matter.
On the other hand, I have been running PS2's on the front and Kumho Ecsta V-700's (very sticky) on the rear of my 925 rwhp SRT-10 for about 20,000 miles without any issues. I need the traction in the rear and this set up works very well for me and likely others.
I don't drive my SRT-10 super aggressively around corners with this set up, but I do drive it as hard as most on the street. Also, I do track my GTS at Viper Days and other events and have done some driving schools. I handle my car fairly well due to lots of practice.
With my current set up, the car exhibts a little bit of understeer when pushed - the car has more traction at the rear.
Someone above said something about seeing the tail end come around on you. It won't do that with sticky tires (most of the traction) on the rear.
If I were you, I'd buy the sticky rears and explore the limits. JonB has the best prices in town - call him. It would be better to upgrade the fronts too, but it's not necessary if you're careful.
