All of that said, I think the best look at your straight line acceleration is on the front straight as you shift into fourth. I honestly was expecting more between 103-113 mph in fourth. Could very well be the hot weather.

Top speed for me on my home track is in the 120-130 range down the back straight. On a 50-60 degree day I can nearly clip 130 mph whereas on a 90 degree day I'm just over 120 mph. Same tires, identical final corner exit speed, same brake point.
Yea the front straight is what really got me wondering. I was expecting it to accelerate a bit faster than it did when compared side by side.
