Okay, we don’t know for sure. But anyone would assume, given the fact that the F12tdf makes more downforce and is 110kg lighter. The 458 Speciale, while being much slower on the straights compared to the 650S, is the better track car, being lighter by 33kg. I’m sure 100kg would make a difference, on top of the downforce. But you are completely correct, numbers don’t always translate to reality so we can’t say for sure. But on paper, the F12tdf will out-drag the 812, and is the better track car.
