“What’s the weight?” 600# heavier than the ZR1.
I was looking at track times of these and other supercars based on your post.
They are all “close”, I agree, at least on paper. Most would come down to the driver. And there are definitely diminishing returns. A McLaren super car isn’t much better than either of these, on paper.
I did Skip Barber and a couple of other faux wanna-be racing schools just to do it.
A lot of the advantages of mid engine are they are markedly more forgiving when something goes wrong. I spun a rear engine Porsche more times than I care to admit in my first day.
Made me appreciate tooling along in my pickup.
