The perhaps glib answer is that you should "early apex" any time it (safely) increases your corner exit speed. Every corner has its own personality. Try shifting turn-in earlier and later, see how it affects exit speed, stability, etc.

I would rather not explain the phenomena as "an early apex," although I often ask drivers to apex earlier and for a longer period of time than they initially practice.
It used to explained "Apex as late as possible, as soon as you can!"

This is where language and exact words become very important. We are talking relative here, not absolute. So it should really be "earlier apex" vs "later apex."

Agree, but your journey at the limit is mostly set in stone the minute you turn in, if you overcook sure you don't add gas at/before/sometimes after the apex, but if you are doing that you aren't going fast you are saving your a** from the speed, angle you approached the corner with which didn't match the capabilities of the car/geometry of the corner

Geez, Mark. It's your words people have trouble with...

I will add another dimension to the mix. My profession race driver coach said to me that in turn 1 at Watkins Glen, as you speed increases prior to braking and using trail braking to rotate the car at turn in, you need to turn in earlier. Why, because the slip angle of the tires increases with higher speed in the corner, so you need to point the car towards the apex quicker to hit the perfect line. Otherwise carry that speed with not the earlier turn in, the higher slip angle will force the car wide of the apex, you will need to lift (car is under steering, more steering input might cause the car to spin and snapping off the throttle could cause the car to spin) to make the exit . There are other turns at the Glen where this applies. As was said, it all depends sometimes
At the end of the day, you want to enter the turn at a point where you can get back on the throttle soonest, be it "early", "late", or anywhere in between. Finding that point is what fascinates the hell out of me with this "hobby"!

T8 is similar but not the same as T1, as T1 is a true 90deg corner (hence "The Ninety") and T8 is more of an angle so you need to rotate the car even more.
Also, T11 leading onto front straight.....the black rubber marks on the inside curbing shows the racers take this much earlier than is taught.

The Ninety's downhill approach, increasing camber gain into the apex and exiting the corner are similar to Turn 8, and you're absolutely correct in calling for more rotation in Turn 8 in order to "open" the exit of the corner and to get to WOT sooner.
T8 vMin is typically 7-9 mph less for well-driven larger, heavier GT cars (GTA2/GTB1) but can be the same in light, purpose built sports racing cars. The key is HOW SOON CAN THE SPEED TRACE COME UP! Cool comparison.
T11 is interesting because the track width at exit is SO much wider than the entrance. This is a superb place to apex earlier, as long as the car is pointed slightly to the inside of the trajectory the driver has selected for it! A lot of very confident drivers do this by being proactive on the throttle and having a neutral car underneath them. THIS is how people start going really quickly.
Thanks for that post. Great track, great concept!

But yes, we can frame it as you ask as well.

Speaking of the Glen, I will be doing a full track walk for Niagara PCA on Memorial Day, Monday May 30, at the end of their first day of their DE, and will be there all week. Very detailed and well worth your time !

Ross' comments are interesting to me, as I trail brake a lot. Maybe I'm already doing some of this stuff and don't know it. I trail brake TWS T1, T3, T4, T5-6,T8,T10 and T13.
