Lap Time: 1:29.3
Max Track Speed: 93.6mph
0-60: 6.6
Skidpad: .89g
Slalom: 67.8mph
Dunlop Star Spec:

Lap Time: 127.0
Max Track Speed: 94mph
0-60: 6.5
Skidpad:.94g
Slalom: 70.2mph

no. i am aware of that. but when you change the tires of other cars, the same thing happens. i just dont see how this is a point in relation to other cars. that happens for every car. what i am saying, is that when you do that same thing with other cars (lets say a mustang or bmw), the performance gain is smaller for the brz.
