Ok, I don't drift my 944, nor do I play a drifter on TV. But there are some things that are incorrect in terms of car dynamics that 944drift posted. I do have a bit of track driving and autox experience under my belt, and it doesn't matter what venue to play in, basic car dynamics and techniques are the same.

So, here goes:

First of all, do you mean THEN HEEL and toe? No offense, but there is a big difference between THEN and THAN. (Then implies the next thing that is to happen, whereas THAN implies rather than doing the next thing stated) But that's just grammar & spelling. I am assuming that you do HEEL and toe.

I heal toe before turning because it allows me to slow the wheels a bit and do a slight shiftlock. I heal toe to 3200 rpm instead of 3500 which slows the wheels just enough not to lock them but instead move the weight and slow you down.
Heel and toe should NOT do anything to the handling dynamics of the car. The purpose of heel and toe is to get the car into a lower gear without upsetting the current attitude of the car while under braking. It sounds to me that you are using the lower gear to slow the car down. This is NOT the purpose of heel and toe.

Than you turn into the corner and brake for like a split second pretty hard this causes understear so when you let off the brake it will cause overstear.
Actually, you have the two (understeer / oversteer) reversed.
Hitting the brakes will cause the weight to transfer to the front of the car. Thus, there is more grip up front. This results in more of an OVERSTEERING attitude. (Oversteer occurs when there is greater slip angle at the rear of the car vs. the front of the car)
Letting off the brakes and appling throttle will cause weight transfer to the front of the car. Thus, you have greater traction at the REAR of the car. This causes more of an UNDERSTEERING attitude. (Understeer occurs when there is greater slip angle at the front of the car vs. the rear of the car)
