Your picture doesn't agree with your description of the track.
That is not a sweeper (that track doesn't have one it seems), but a hair pin.
What you experience is liftoff oversteer (if you drive a FWD car you can experiment with this on a suitable road). This is a classic shortcoming of FWD cars and it is usually addressed with a lower ride height, placing more weight at the back, or anything that will help keep some load on the rear under deceleration. All of this will affect the balance of front vs rear grip. Another way to control this tendency is to accelerate mildly thus preventing rear end unloading. this requires a change in driving technique. You need to slow down on the short straight leading into the hair pin and start accelerating before you enter the hair pin. Again, this acceleration needs to be pharmaceutically adjusted to keep the car loaded just right. Keep in mind, you're not trying to gain speed, but to keep the car together around the hairpin.
