Interesting. Is that with the wings at max or min settings?
All tested with my race setups for each car, I have driven them all on various circuits, so these were the setups I tested them at, obviously you can modify those values with wing choice.
but the basic downforce is inherent to each car, that will remain.
I use much more wing on the Mazda than any of the others, for me, it gets very twitchy with low wing settings, so, I think I drove it at Silverstone, had to swap straight-line speed for not constantly coming off.
If the Mazda could be driven with a very low wing it would be very quick, not sure about it, just from memory, I think I tested it at no chicane le mans.
