A friend decided to lend me his Audi R8 V10 I did two laps, one in the morning and this one was at mid day a trackday, I didn't though to reach, i guess this quite fast laptime but i'm was very proud to do it in two laps only for this day and 6 laps overall for two years.
I think honestly this car can reach the sub 7 .

My laptime is available on Harry's Laptimer App in "challenges" i wanted to share it , you can use it if you want to analyse the driving .
