indeed it is a kind of headache, so I took a bit different approach :
- the length is quite short, so there is no particular wear of the tires to take into account, only heat => optimizing camber to have something homogenous is then not required, it is better to overheat a bit the inside part of the tire.
- R2 or R3 are clearly a bit difficult to keep on a correct temperature after 15 laps, so I have chosen R4 in the end (even mixing was not giving good result as cooking the rear tire is not a good idea neither)
- I give a look to the two setups you shared and they are quite stable
, and so they tend to be not that good with the front tires
I have attached a replay of me doing 40 laps (~half race) with the setup. After the front tire is going a bit hot indeed I am forced to loose ~1s per lap. But you can expect doing sub 16s for around 15 laps and then release a bit the thing around 16s for 10 more laps, and then target 16,5s-17s for the rest of the run.
