Hi
These are the things I would look at;
1) You need to run the cars ride height the same front to rear higher at the rear than the front (typically I run indoors 19mm at the front and 20mm at the rear).
2) I would remove the 2mm under the steering block (i.e the 2mm of bump steer yo have put on) .
3) I would go to a 55 piston, move the shock into the middle on the tower and lower your rear camber link to 2mm maybe even 1mm both on the inner and outer.
To me the back end of your car is set up to roll and generate a lot of drive, and then your front end is very stiff. So in my opinion as you go into the turn you release the throttle to turn in and the weight transferes very quickly to the front outside wheel which doesnt give at all and then it flips. Now I am by no means an engineer, so I could well be wrong but this is the way I see it looking at your set up. I have been running the car on medium grip carpet and wood down at maritime as well as at Faversham over the winter and I have not suffered the problems you are having, so maybe have a look at my set up and use that as a starting point and tweak it from there to your liking.

I've posted two set up there, one which is mine and the other which is a starting point set up for a standard out of the box kit, as mine has the 4mm trailing axels and a few other bits that you may not have if you have only just got the car. I believe Billy ran the set up I suggested and said it was a good starting point if you dont have the extra bits.
