Unfortunately, the track limits at the chicane are quite bad at this track, I had this confirmed on the forum that this is as designed, as they are allowed to do that at the real Blancpain Sprint Cup round at Hungaroring.
I'm just above 1:32 myself. 1:32.2xx something. I read on the official forums that changing the brake bias and lowering the TC can gain you sime time. Will have to test it.
