Big aero and big breaks really helps at your local track.
Really surprised the Viper only beat the Z by a little over a tenth of a second. In the hands of pros, I would expect that margin to grow to more than a second.
Reread the article, it was in the hands of the editors in other words average guys.
Theres a portion that says Chris Winkler (ACR engineer) was doing 135mph during a corner, in the same corner the editor would instead brake and be doing 110mph.
I'm also not sure if the ACR's brakes are bigger than the P1, 918 or C7Z. Surprised the C7Z didnt overheat.
