I just don't have what it takes to tackle the longer TT's with silver and gold, once again I'm stuck with bronze.
See, Le Mans is more of a track for professionals and aliens who know their driving skills to the bone.
Something to try on a TT you are having problems with: Load up a fast ghost replay, it doesn't have to be the fastest, then go into the driver view you use and watch the lap a few times without really trying to digest anything, just watch it, you may pick up something you didn't notice before.
Then watch the lap and pay close attention to one part of what the driver is doing, such as braking points. Watch the lap again paying attention to braking points, but after each corner pause and rewind, watch it again, try to understand exactly where they are braking, how much they are braking, and how fast they are going, and where their car is on the track, and the angle the car is at before braking.
Then realize you won't be going that fast on your lap no matter what, so it'll be braking too early for a slower speed, but braking too early is better than too late and you probably can't brake as efficiently as they do anyways so use their braking points even if you're going slower at the same point. Also realize the faster you go, the earlier you'll need to brake.
Then do the same paying attention to when they are shifting, how far do they rev the car up in the rev range? Are they using engine braking and how much? Id it different for different corners?
Then do the same watching the throttle inputs, then steering inputs. You may have to switch to cockpit view to get a better idea of their steering inputs.
You cannot possibly take all that info in simultaneously in real time watching the lap, you really need to pay attention to one thing at a time and get some understanding of each input made and why. Eventually you'll get to the point where you start improving, mainly because you know what to do even if you can't do it perfectly every time. And you may totally forget what they did in a corner, so go back and review that corner again, then try again for another session.
I usually go in blind with no ghost and try it myself and sometimes I can gold them that way, but I usually at least need a fast ghost for reference, and then might turn ghost off and gold it without the ghost. Ghosts can be distracting and hypnotize you a little bit. But if I have no idea how to take a corner and can't figure it out, I learn from the people who have already perfected it. I still can't go as fast as them, but at least I have a reference point, a target to aim for.
No matter how slow or fast you are, there's always someone faster and you can learn from them unless you're in the #1 spot.
That Lemans TT was easy for me probably because I've run that track so many times in single player, testing different strategies for fuel and setup, while grinding for $$.
I was 💩 at Bathurst because I really didn't understand that track. I golded it but just barely, but I have a much better understanding of that track now.
I can't remember if you're using a wheel or controller but if wheel, don't be afraid to experiment with wheel rotation and force feedback settings.
If controller good luck, I can't gold these with a controller 90% of the time but on that RBR Mitsubishi EVO TT my wheel time was only a few hundredths faster than my best controller (with auto gears) time.
You definitely can get faster on the LeMans TT, but you may need to study someone's alien lap a little more in depth.
