In most cases I would agree, but these tires are on a different level. Best production car in the world gained 2 seconds, and the margin would only get greater with a less performing car.
The trofeo tires were the deciding factor from the manufacturers agreeing on testing the laferarri vs p1 vs 918, for what its worth. The p1 dropped 2 seconds going from the p zeros to trofeos.
11% drivetrain loss seems like alot. My 2003 lightning with an auto is 14%. Is MT saying ford falsified the engine HP #'s?
Edit: Correction, alot of lightning owners are seeing 11% through the old 4r100.
