Now you know that the ceiling corners are the ones that throw you to the wrong place and you have to think ahead so you don't fall on the trap. In this first example we have a small kink to the right right before the breaking zone into a very complex set of three corners at the second sector of Sebring. If you're not aware of that kink and how close the breaking zone is after that you will stay too close to the white line and then after that kink it's going to throw you to the middle of the track and you will not have enough time to bring it back to the ideal place or what we're going to call the checkpoint of the next corner.
What you want to do instead is use your planning vision your mind's eye to already prepare a line before by moving the car a little bit earlier to the middle of the track and then going around that kink in a way that will already align yourself to the white line after the kink so you are already on the right spot for breaking.
Deceiving Corner Sequences
Right after that corner we already have a deceiving situation. We have a left hander that leads into a right hander and kind of throws us naturally to the middle of the track here. But this corner here is incredibly important because there's a huge straight right after that. So what I want to do is not be deceived by this and create a checkpoint right here.
We want to bring the car as much as possible to the right to maximize this line and benefit as much as possible. Bring the car as much as possible to the left here and change direction and go all over this curve to make sure that by the time I land I'm really as much as possible to the right. Here as soon as I get right here my reference is pretty much the end of this little curve here. So that's my checkpoint. I want to be as close as possible to the white line at the end of this curve and know that if I get my car here I'm going to maximize this next corner.
Understanding Line Dependencies
Of course it's not going to be that simple to just hit the car where you want because if you're on the limit the line that you take here is going to determine where you land here and if you land a little bit too much to the outside then you won't be able. You're going to be a little bit stuck here and then by the time you cross this curve you're going to land no matter what you want to do you're going to land on the middle of the track.
So you have to think ahead three corners so you get a later apex on this one so you get a better line more to the center of the track here not going here so that you can then cross this track and finally land on your checkpoint. So your checkpoint might depend on a sequence of corners before but we're going to talk about that in better detail in the compound corners lessons.
The Breaking Zone Alignment Problem
Next up we have one more corner at Sebring where we have the same problem. We have a line here that invites us to stay to the left and then that throws you more or less to the middle of the track and then you want to come back while already breaking which causes you to lock up the tire which is the same problem we had at Detroit.
If you lock the left tires because you're turning left a little bit here and shifting the weight to the right by the time you start turning here you're going to use the tires that are overheated and you have a lot less grip.
Skill Level and Problem Manifestation
On a beginner level you go all the way here and you have a terrible line for the next corner
On a more advanced level you're kind of thinking about that but you're still moving a tiny bit to the left and you end up micro locking and overheating a little bit the tires that you're going to use during the corner
Depending on your level this problem can show up as a big one or a very tiny one that makes you lose a tenth maybe half a tenth but you have to be aware of it
So what you really want to do is make sure that you're perfectly aligned to this white line and on a straight line by the time you start your breaking. As a matter of fact I got this replay from some months ago to try and show you this example and I'm going to show you that I actually made the subtle mistake of still breaking while the car was moving a little bit to the left.
As you can see I don't bring the car fully to being aligned to this white line here. My car moves a little bit to the right. Now I have a few degrees that I'm moving to the right under breaking and you can see that I'm not fully aligned to it and I'm probably losing one two three four hundredths of a second because of that. Actually not only that I lost a lot more because in this example I missed the apex.
Kinks Leading Into Actual Corners
Here's one more example of the deceiving corner this time in a double lift. The examples before were changing direction but this time we have a kink to the same direction we have a kink to the left that takes us into an actual corner to the left. This is a footage from a student. He was deceived by this curb here. You look at this and you think oh it's a curb. I'm going to use it right. But then he then finds himself in a much more difficult corner, an actual corner that you need to slow down to do.
Now right now he is in a wrong positioning. If you think of this corner, if you ignore everything that happens before, if you think only of this corner what would be the ideal position? All the way to the right and parallel to the white line here. In this case parallel to the curb. But he is on the middle of the track and pointing to the outside. So because of that his line is severely compromised because he was struck by this corner here.
So instead of actually ignoring this corner and focusing on a checkpoint, he was baited into using this corner here and then finding himself in a terrible position. So again, the deceiving corner, the solution is to have a checkpoint right here and then do this corner thinking about that. So when you're here, your mind's eye is already all the way here. So you ignore this apex on purpose and you find yourself in the perfect spot for this corner.
Checkpoints Before Long Straights
One more example of a checkpoint that is super important is at the oak tree corner here at Virginia. You can already see how long this straight is. So you need to benefit from the best exit possible from here. And in order for this to be possible, we have to have the perfect line on this corner. So this corner is the full priority of this entire sector, which means from this corner here, you have to let the car run all the way to the outside. So we have a checkpoint right here.
But it's a very, very, very common mistake to see a lot of students bringing the car to the inside here because they're over-slowing and being afraid of catching this grass and they stay on the inside, they stay on the inside and by the time they turn into the corner, they are not capable of carrying as much speed as possible on this sector here. You can see how it's on the middle of the track literally. And then not capable of getting the best exit possible.
Additional Checkpoint Examples
Autumn Park Turn Two
One more example of the deceiving corner, Autumn Park turn two. We have a slight kink right here, but the actual checkpoint should be right here. So make sure you go around this kink by going to the left and then crossing this going around this so you can find yourself in the perfect position for the actual corner, which is this very fast left-hander.
Autumn Park Double Apex
And here still at Autumn Park, we have the very fast double apex, which is this right here. But before this corner, there is this tiny kink right here that generally makes everyone go to the middle of the track. And by the time you get here, you don't have enough time to bring back the car to use all the track right here. So we should place a checkpoint right on this entry here. So we make sure you can get the best line possible for the double apex, which is one of the most important corners that leads into a fairly long straight.
What you want to do immediately know that this is a checkpoint. So go around this corner here by staying to the right and then bringing the car late to the left here so you can have this best line possible. A lot of people just go here and end up getting thrown to the middle of the track. And then they have a terrible line for the actual corner.
The next lesson we're only going to talk about double corners, double left and double right. These corners are great in making you go slower and lose time. So that's why we're going to tackle them.
