VDC off???

There are 2 issues at play in your above description.

1st is the brake/throttle interlock. This car cuts throttle input if you touch the brake. The stop lamp fuse should address this.

2nd is the ABS itself that works in conjunction with the stability control. Touching the brake has a tendency to "straighten" the car out. I think you would have to pull the ABS fuse to correct this.

Yup that's exactly the issue here. Even with my foot off the throttle, mid way through a drift if I wanted to slow down, pressing the brakes even lightly would straighten the car out, as if the VDC was switched on again.

Does removing the ABS fuse disable the Bosch yaw sensor? I really don't wanna take off the center console all the time.

It does, but the car has a natural rear bias in the braking system so without ABS you will easily lock up the rear brakes. You would have to find super wimpy pads to put in the rear.

are you sure the car will straighten itself out with the vdc off? with vdc off, only the abs and abls work. abls doesnt really stop your drift, it just limit wheel spins. no?

Well if you are at a 45 degree angle I don't know what it will do but at lesser angles yes it does seem to. Perhaps not as a result of any stability program but rather stopping all wheel spin will return grip. It seems to apply the brakes intelligently in corners even with VDC off in that you can brake as hard as you want and it will never upset the car.
