hey, this is oddly familiar.
ok. Provided that you are using the settings I made up at the time we posted the drift reference, then I think more than anything what you need to work on is your countersteering.
You start to get a little slip at the rear but then in te replay it looks like you panic and turn into the drift much too hard.
Also, I think the stab of the brakes was a little unnecessary and probably didn't do a lot for your drift. If you're using the settings that I think you are, then that car can enter that turn much faster.
If you watch the Feint example here:

I did apply slight braking pressure to move a little weight forward, but it was not a full stab at them. My feeling is that fully applying the brakes as you did unsettles the car an unnecessary amount, significantly reduces the effectiveness of any steering input for that period, and needlessly sheds speed.
oh, and I now appologize for the terrible quality of the demo vid. I was quite a novice to the whole video capturing and compressing thing at the time.
Also, I'd like to mention that the settings posted for the Miata in the reference were made shortly after GT4 came out, so keeping it on a low budget was a priority. My thinking was that people at the time did not have large sums of Cr. accumulated in their games to go out and fully tune their suspension and driveline, or reduce weight significantly, etc etc. It's a minimalist setup in my eyes, and somewhat limited in the corners it can effectively handle.
