View Full Version : Racing line

Hey everyone.

I have a question:

It happens to me very often, that I sometimes lose grip in the same corner. For example: Lap 1 -> Good grip. Car feels like it's attracted by the apex.
Lap 2 -> No grip at all. Heavy understeering and stuff.
I don't think that I'm off the racing line. So what's the clue?

Anyone else who's experienced sth similar?

Greetings

Which corners are these in particular? One phenomenon is that corners near the starting line aren't taken as quickly simply because you haven't built up enough of a head of steam. I feel like this effect can carry into later turns, but by the middle of the lap you're up to speed. By lap two you're into turn one again much harder than before, so maybe the grip level seems less (but you're actually asking more of the car).

You say you feel less grip but maybe you're racing harder by the second lap so it seems like you're on the limit more quickly?

Another possibility is that you're not using enough grip on lap one, therefore you don't generate heat to keep the tyres at temp and lap two will be with less grip. This happens even if you are racing hard at tracks with long straights like the Nurburgring, where on lap two if you take the first set of corners like you did the first lap you'll spin.

These are just some ideas. You literally should have more grip on lap two (if anything).

I think of recording the issue. It's hard to describe.

THanks for your reply, but I don't think it's the tire temperatur (always an eye on them).

Which car, track/corner?

Post a video or tell us which car ,track and corner so we can give feedback although I think what Bouyo said pretty much sums it up .

I could say "every car and every track", but I raced the Marek LMP 2 on Spa Francorchamps yesterday. In pretty much every corner I had this feeling.

T10, 11, 13, 14 -> Try these.

It is not uncommon for tyres to lose a bit of heat and grip over the first few laps, even in TT mode. On lap 4/5 on most tracks, you should see temps and grip increase again, if racing on a dry track. I usually set my fastest lap after lap 5 on a dry track, even in TT mode.

Can I ask, what sort of lap times do you normally run around Spa?

The only thing I can think of has been referred to above. Any cars that use significant levels of downforce, like the LMP2 cars, have tyres that need to be worked hard to stay up to temp and pressure. If those temps drop, even by a few degrees, the grip should change enough for you to feel it. The other thing it could be is your tyre pressures are set too high, so once everything is up to pressure (which could take about half a lap at Spa if you're pushing hard enough) the tyres are too pressurized to grip correctly.

There are also some corners that just encourage the car to understeer. Rivage (Turn 10), Turn 11 and Pouhon at Spa are perfect examples of this.

Antoher "no grip". Watch how the car understeers on corner entry:

And then two "more grip" videos. Here you can see clearly the difference. In more grip 2 I carry even more speed into corner entry than in no grip 2. But surprisingly the car feels attracted to the apex. You can see it how the car tilts to the right. 2 tenths faster than "no grip 2":

And the last one. Again 2 tenths faster through both corners.

It depends on your braking. If you throw a car into a corner while still braking or changing gear, you lose grip easily. Brake a bit earlier, make sure you're in the right gear then turn in. As for understeer, you could be turning in a bit too late or in the wrong gear. For example, you probably think it's best to go through the corner after Eau Rogue in 3rd gear to get better drive through the turns when its better to change to 2nd for better turning then change back to 3rd if you can't get traction in 2nd

Edit - also last turn at Watkins Glen is a prime example for understeer. You turn in thinking it's early, but you'll miss the groove. You can turn in a lot earlier than you think then let the track spit you on to the straight

I would say it's all about your driving style.. Lifting of a little earlier could result in a totally different attitude trough the corner.

I wrote that I carried even more speed into the corner and still had better grip. Makes no sense to me at all and this is what it feels like to me. Sometimes grip. sometimes no grip.
I'm plaing racing simulations for a long time but I never had such an experience.

+1 i have the same feeling. It seems that the grip changes.
Many times, i've not been able to take the last corner before the straight line in Hockenheim at 80 km/h and i don't understand what happens. The car don't turn.
