So i drove a GT4RS today!
It did a 1.10.6 with Cup2 tires and a co-passenger 
The car could do low 9s i believe if I am able to drive it properly...
It was the most dialed in car that I ever drove.
I was not pushing to the max as the car was brand new and the owner was sitting next to me and I was so careful with it. The car gives you so much confidence and it is overall amazing! 
The camera angle was a bit shit. I did not notice at the time :/
