Lightest possible 458 Italia to be configured for the U.S. market, with over $100,000 on options, still hits the scales at 3,400 lbs (too heavy), 130 lbs heavier than the MP4-12C with the 12C having the big stereo.
The ZR1 is geared long, it is light on the rear end so it suffers when launching, and it doesn't have a trick transmission. However, with its runflat MPSC 19"/20" tires this car lapped the Nurburgring in 7:19s, faster than the MP4-12C and the Italia by a decent margin.
At a racetrack (I don't call a drag way a racetrack), 0-60 mph or 0-100 mph means nothing. I look more to the acceleration from 80mph up to 120-130-140-150, as while exiting a turn at a track I have to limit the application on the right pedal until the car can take it a full tilt, a point that is typically located above 60mph at most racetracks.
On experienced track drivers hands, these 3 cars are very close in lap times.
I would personally place them: MP4-12C 1st, 458 Italia 2nd, ZR1 3rd.
Good point. The acceleration tests at El Toro (and the 12C numbers show valid numbers), then the track day in super hot Nevada weather with the heat management protecting and slowing down the 12C.To be clear, the track portion of the R&T test was not at El Toro. It was done at Spring Mountain, using the short 1.5 Mile Radical Loop. Ambient temp was 96 deg F and the 12C DID torque down during the lap due to thermal protection kicking in.
Not sure if you knew, since I think you said you drove a standard brake car, that the CCB system has extra cooling ducts that pick up airflow from under the flat bottom. You can see one peeking out in this pic:Good point.

These type of issues: limp mode, my predicted insufficient brakes when using real track tires, and any other is what I'm looking to find about this car. Fortunately, the 12C-GT3 is serving as a test platform, and some upgrades get added in 2-3 years.
