I forgot to hit record for my PB lap of 1:53.65 so this is the next best lap from the day. I was actually on track for another 1:53.6 but out braked myself at T10 which result in messed up rhythm for T11 as well. Had another chance the following lap but they throw up the checker flag too early by mistake. 

With the excuses out of the way. The most significant upgrade is the @VerusEngineering front splitter and canard as well as the @aprperformance719 GTC-500 wing. The aero balance is pretty much perfect and even though I am losing 3 to 4mph in the front straight, I make it up in the turns easily. All in all the aero shaved about 2s from my previous PB and I am sure there is another 1s once I get used to the new limit.
