Wouldn't the brake cover be Aero and therefore described in the FIA upgrade docs? Everything inside might be different, but is still aero though, right?
The tires seem to warm up very quickly still, it is possibly the deformation of the tyre that has changed and improved as the sidewall has almost certainly become stronger and more rigid. Possibly there is also strengthening under the surface of the road gripping rubber and this could affect the transfer of heat. But if it was to do with how the brakes are able to pass heat to the tyres they'd jave had it under control a long time before, I think. I suspect it is more likely to do with how the car needs to be driven causing a lot of energy to go into the tyres.
Perhaps I agree. With all of the above arguments. In theory, yes, this is an aero package, rather than a mechanical part. But looking at the analysis of tire degradation, McLaren is still where it was before, except that downforce significantly offsets the overall drop in racing pace. But the degree of tire degradation is still bad compared to other teams. But, Hungary turned out to be a very tough test given the soft tire compounds, hot weather and its most comfortable corners.
I agree, but it is why I don't think it is an Aero issue per say, but that the method of getting time from this car is not good for the tyres or there is work to do on the mechanical side.
The RB and Mclaren rear suspension appears not too different, so it would be interesting and useful to understand if Mclaren have deg issues on both rear and fronts, or just fronts.
That said, it could well be that the balance of DF produced by the floor is too rearward or not optimal in general. We do have good traction and corner exit.
I managed to see the onboard of Alonso, George, Oscar, Lewis. From Turn 2 and Turn 13, I can say the following: Aston has been understeer since the start of the stint on all tires. That is, all three full stints are this. The Mercedes are very stable in the beginning, but towards the end of each stretch there is oversteer both in and out, with good front grip. Oscar lost some grip at the back, but I didn’t see anything critical, again, he had a damaged bottom and a drop in rear pressure, which caused the rear tires to go faster. But the overall balance of entry and exit was more neutral than it could be called understeer, which surprised me. I would say that McLaren did a good job on long slow corners.
If you look at the pace, McLaren is very fast on fresh tires, the drivers squeeze much more out of the tires, and the Mercedes ride more calmly and accelerate in the final phase of each stint. For example, why did Lewis, who was within 3.5 seconds of the first pitstop, lose 7 seconds after undercut to Lando and be 9 seconds behind Oscar? Then two laps later, the gap between Lewis and Lando widened to 12 seconds. It was 3.5, now it's 12. How? After all, the undercut on fresh tires worked well, and no one interfered with Lewis. The answer is generally simple, McLaren tires wear out faster and drive slower at the end of the segment, Mercedes, on the contrary, drive the entire segment more steadily, but the overall pace on each segment is comparable. One man's analysis confirms Lando and Lewis ran the race at the same pace.
I haven't watched the Red Bull onboard yet, but I think they have more grip at the entrance to turn 2 and 13 and that helps a lot. Luckily for me, McLaren didn't have any big problems here, when turning the steering wheel the chassis obediently entered the turn and there was no understeer. But if Lando wants to use the V-trajectory, then he will need more grip on the front tires. So it is with the front suspension that you need to work.
