i dont know that heavy braking is necessarily the solution, too much braking can upset the cars balance at turn in, depending on individual technique. It certainly is an option though.
What others have said is true though. Concentrate on carrying slightly less speed into that corner from the previous one. Whether that means staying off or feathering the throttle, or just exiting the previous corner slower is up to you. You decide what works best.
Also, try turning in sooner. I found that the proper turn in point was one of the hardest parts of drifting for me to catch on to (i still have some difficulty). Its often earlier than you think it should be - or is/was for me.
When i enter the turn after the first tunnel on Midfield 1, i start my turn in from the farside of the turn almost as soon as I exit the tunnel. My turn in is helped by feint motion that i've carried through the tunnel from the previous dual-apex right. This gives me a tight line around the apex.
Granted, I do still have some problems with my line and I am aware of it. But i do find that line to be effective, at least for me. However, your own style, and to a great degree your vehicle and its setup will define the best line for you to take.
For instance, i will typically use feint motion to initiate drift on that turn, so a wide entry is preferred in that case. If you were to use a braking entry, you might choose a slightly tighter line since your speed will likely be less. Either way, once the thing is sideways use countersteer and throttle management in harmony to maintain your line. I emphasize this point.
Throttle control and countersteering should be kept as smooth as possible to ensure a smooth drift. Even though in reality they are generating opposing forces, they should not always be viewed as such - they are both essential to pulling off a controlled drift (FR and MR at least). Dont give a brief blast of throttle and then pour on a bunch of countersteering to regain control - this is not very effective or efficient. Do everything as one fluid motion. Balance is what it all boils down to.
ok, with all that said and behind me. It would probably be beneficial to all of us trying to help if you ould post a video of your drifting - if you have the means to do so. Or at least settings of a particular car that is giving you grief around that turn.
👍
edit:
just occured to me, that i usually end up offtrack tail first when i over rotate the car. If this is what you're experiencing try carrying a bit less drift angle through the turn for awhile, it will allow for a little more control. A video would be very helpful.
