I have a question that maybe someone here can answer.I have a 2008 335i w/sport package and it seems that I am going slower than most and it feels like I am not going the same speed as on the speed odometer(slower).Are these cars calibrated with the larger wheels or is it the same rolling mass as the 17in. wheel package.
I traded in a 2008 Vette for this car and in the Vette at 70mph it did feel as if you were going 70mph.
