Something doesn't add up: the gt2 rs takes 87 feet to stop from 60 but almost TWICE that to stop from 70. and the Senna is only slightly faster around NCM and Silverstone, and the GT2 RS is actually faster in the rain. I'm not sure how this went down, considering the GT2 RS is uses old school tricks to go fast and the Senna has active aero and weighs less and has like 100 more horsepower. To put it this way, the GT2 RS is The Beatles and the Senna is like Drake. Both super fast, or popular in the music reference, but they get their speed (popularity) in different ways

The stopping distances are different because of different tests and diffeeent conditions. Cold and hot tires make a huge difference.
In the Mclaren Senna test alongside the gt2rs,
Stopping from 60 and 80mph,
Senna took 111ft, 181ft.
Gt2rs took 108ft 183ft
Pista took 108ft 181ft.
All of the results were close enough to be within the noise, virtually identical. Also The process of “braking at the line” by different drivers yield different results because, some brake too soon, some brake too late.

The Mclaren has to be at least 3 seconds a lap faster to justify its terrible looks.
