Well there you go, did 6.56 on version 0.61 with softs and low fuel after about 6 laps. Not that far from default, just a bit less rear wing and better on bumps, brake bias should be pretty neutral aswell (unlike the default setting)
I will be running this in the race tonight.
It is rather soft and understeery at low speeds. Because I am running low rear wing, it is neutral at high speeds. I can do 7:15s (medium tires, 65l fuel) with it, but a more competent driver could go quite a bit faster.
Beware: I do not know what I am doing when it comes to setups so take it with a grain of salt.
