It's a quirky one. I actually found a bit of a trick to drive her.
I use the DRS aspect of the boost button to better get through some corners.
For example on the Nurb Turn 1 is under the speed the flaps deploy to fly the car through the corner, but as soon as you exit the speed crosses over the trigger speed and the flaps come out. Then the 2 slight kinks right can be seriously touchy, lotta oversteer.
What I do is as soon as I exit turn 1, I hit the ERS/DRS modulating the throttle to make it through the corners the car drives like any other. AS SOON as the car straightens out I release the ERS/DRS button as speed becomes so fast the flaps help through the next section of corners, you got to give fast preemptive inputs, corrections must be fast. The car responds well to digging into corners.
It feels twitchy when inputs are too slow, speed them up and she will reward you.
The long uphill climb is crazy fun flat out, just be quick on the wheel and you can stay WOT from exiting the right hander at the start, all the way to the left hand sweeper at the end.
I'll get my equipment set up later and record the lap. It's not the fastest, but its fast and clean. 4:42.5XX seems like a good time to me
