Stop in for a cup of coffee

I've noticed the road surface and the tires make a big difference.
NJ Motosports park was pretty rough on the outside of the straight at those speeds. Was using the Toys R888R tire but I was told alot of it is that track.
At Atco through the lights over 100 mph and it felt pretty good. That was on the street tires.
There may have been other times at those speeds where I've noticed it can be really smooth and nice or rather noisy and rumbly - like a box van as Tim said.

approaching Turn 1 is quite rough
