One thing I have found to contribute to the car dumping over like you describe is running too big of tires. I've recently been running tires pretty small even for club racing and find them to work great (starting them no bigger then 41mm or even smaller).

Running 5k or 7k in the tubes you might actually be dumping all the weight too fast. Are you also running really soft side springs? A basically "standard" setup on the car you are running is .50 side springs with 20k in the tubes. I would start with going up on tube weight and see how that effects your car. Like I said with the super light setup you are likely just transferring all of the weight upon turn in and then all of the load is put on the tire. At that point the tire simply can't hold on and you are experiencing a spin out.
