In our video above we are onboard with Steven and we see the car in front is quicker than him through this section. In this article and in the video we breakdown exactly what the car in front is doing to be quicker than Steven.
Early Apexes Prevent Earlier Full Throttle
There are a few errors that we have to work on correcting to help Steven find time and we will list them in order of importance here.
###1 – Apex Point In Turn 5
In the photo above we can clearly see the different apex points for each car. On top of that, we can also see a very different angle for each car. The car in front is apexing about 3 car lengths later than Steven.
The driver in front gets more of their turning done earlier in the corner. This fact combined with the later apex allows the driver in front to start unwinding their steering wheel earlier on corner exit, which allows them to get back to full throttle earlier at corner exit.
Getting a good exit is not always about getting to throttle first there are many factors such as minimum corner speed, steering wheel input, and when you get back to full throttle. We have a great article on how delaying initial throttle can actually help you corner exit here.
Steven’s early apex is having a big impact on getting on a good exit out of turn 5 and he is losing time all the way down the straight to turn 7, that is why it is the first thing we want to see him fix.
###2 – Apex Point In Turn 3
Here we can clearly see Steven is again apexing too early. Again we see the difference in car angles between the two cars. The car in front is angled slightly more to the left so again they can start unwinding the steering wheel earlier. Steven from this point on will need to actually add steering wheel input into the car.
He will be running out of track at corner exit because of this early apex, this will make him over slow the corner and will negatively impact how aggressive he can get to throttle at corner exit.
The reason too much steering input does not allow Steven to be aggressive to throttle is because of the famous “string theory” for racecar drivers. Here is a great article going in-depth on this topic.
We want Steven to delay his apex until the very end of the apex curb, which is the perfect marker for almost any car in this corner.
Slower Turn Ins
Here we will look closely at the turn in points for turns 3 and 5. Is Steven apexing too early because he is turning in too early? Let’s take a look!
It is a little hard to tell but in the first image, we can see the car in front just starting their turn in just past where the apex curb starts. We can see a darker rubbered in line to the inside of the car.
In the second image we can where Steven is beginning his turn in point. The spot is nearly identical. Steven is also just as far to the right as the car in front. So, why is Steven apexing too early if he is turning in at the same spot?
Steven’s rate of turn in is too fast. We want to see him slow down his hands during his turn in process. This will slow down the weight transfer, allow him to roll more entry speed and delay his apex spot.
In the first image, we can see the car in front is turning in just as their entire car gets passed the last cone on the right. It is hard to tell in the second image but Steven only gets about half his car passed the cone before he starts his turn in.
Steven is turning in slightly early into turn 3 but that small of a difference at the turn in point should not equal that big of a difference at the apex. So, what else could be happening?
You guessed it, here he is also turning in too quickly, just like in turn 5. So, we need him to delay his turn in point by half a car length and slow down his hands after the turn in so that he can execute on that much later apex.
Maintenance ThrottleIn this short video above we can see Steven has a constant throttle of about 40% or so from the exit of turn 3, through turn 4 and into turn 5. We would rather see Steven be a little more aggressive to throttle out of turn 3 and then have a bigger lift into turn 4 and another more aggressive squeeze of the throttle out of turn 4.
This dull maintenance throttle means Steven isn’t using the weight transfer of the car to help him maximize the cars level of grip. With that maintenance throttle, Steven has an on throttle understeer through turn 4. This pushes the car to the left and he can’t get to more throttle out of 4 or through turn 4 because he needs to keep the car right to set up for turn 5.
A more aggressive squeeze of the throttle out of 4 and a bigger or even a full quick lift into turn 4 will have him arriving faster into turn 4, but he will be able to make the corner because the weight will shift back towards the front end helping the car rotate and turn. This will allow him to keep it right at a higher speed and the extra rotation into turn 4 will allow him to be more aggressive to throttle into turn 5. That will give him additional speed at the entry of turn 5.
Here you can see the power of analyzing your video after a session. While we are on track things are happening so fast and we need to be entirely in the moment. This makes it very difficult to analyze why another driver may be faster than us through a section of the track.
Being able to spend time in between sessions in a calm environment analyzing your driving will help give you answers to how to find speed. Often times drivers will pick up on small things they are doing on the race track that they didn’t even realize they were doing. Video and data keep us honest and gives us a different perspective!
So, even if you aren’t considering receiving pro coaching from our elite coaches at Blayze where they can watch your video and give you specific coaching just like in the video above, we highly recommend taking the time to put a go-pro or similar video device in the car. Spending just 10 minutes in between sessions to watch your video will make a significant impact in your improvement as a driver!
