I tried the 3rd gear suggestion but was much slower than my best sector time...
Went back to my previous set, high 5th on the straight, brake hard a bit after 100m (before the cones) to 2nd for the first turn, get out of Senna S pushing 3rd, finish first sector on high 5th again... reduce to 3rd and start accelerate as soon as you hit the 4th turn curb, go high on descida do Lago until ferradura roping 4th gear brake a bit and reduce to 3rd to 7th turn, 8th and 9th is 2nd gear, 3rd from pinheirinho to bico do pato, reduce to 2nd again, push 3rd and 4th in mergulho and turn junção in 2nd push all back again....
Best I could do so far is:
30.381
58.340
Will try to improve this and get better with those 3rd gear corners
