Are you sure you don't have the car so tight on entry and middle that it "snaps" loose from the middle out with all of the wheel input?

For a winged car, I would think that you may want to go with a pair of 1000's in the rear or maybe even a .975LR and move the LR out some.

Often; a car that is loose off is the result of a car that is too tight early in the corner. Drivers typically remember that it's loose off, but forget that they have been compensating for a tight condition in.

As it looks from your numbers; the car has alot of Static LR in it and often a car that has a lot of static LR and is driven in the corner straight as most wing cars are; they tend to stick the RR hard and then the driver is forced to really crank the wheel and the car over rotates. With a little less LR bar, the car can rotate or roll the center easier and with the LR wheel out, the car can wing down a little easier getting off.

All wing racing is about momentum and you have to roll the center. If a car turns in nice, rolls the middle and wants to spin the tires getting off, then you can keep the car loaded with the brake. After you get the car turned, you can use the inboard brake to load the chassis because as the brake is depressed the energy from the the rotor causes the car to push down on the rear and load the chassis. If you are out of the throttle for an extended time and then try and get back to it, that too will cause the wheels to spin. The Dri-Bar systm is a great tool as well, to use it to it's fullest potential make sure that your car is as good as you can possibly make it.

Maybe I am wrong, but always study your problems starting with corner entry through corner exit.

Best of Luck
