Awesome clip...looking hard at a Senna now. Someone mentioned too many variables...tires, conditions, same/different drivers, familiarity with each car...etc. I think the Senna can generate 800 lbs of down force. Love to see GTR vs MKII and Senna vs 2020 NFGT...looks-wise, not even close. The Senna, with all the passive and active aero up front, hangs way too much in front of the center-line of the front hubs...looks like it needs braces due to huge overbite. NFGT is just stunning.
