Well I've got this far.
what you don't see is like 7 laps more before that
but it seems like I need more practice.
Setup: Reduced final ratio with 5th and 6th shortened as well. At the end of the straight it's hitting around 265kph and topping out. No TCS or ABS. Rear wing increased by 1deg. Front toe reduced by 1 on each side. Front bump increased by two clicks, and rebound by one. Diff power set down to 30%. Didn't touch anything else. It handles like a dream now, I mainly changed it to handle just like the AMG GT GT3 because I love the way that thing handles and sounds.
I watched DerBayer's video, and he's got literally more corner speed in every corner and higher exit speeds.
I'll upload the video of me doing the 1:55 soon.
