I don't think its heat that's the issue rather the Cup2 has a much stiffer sidewall. Also a big part of why the CFTP is THAT much faster around a track.

Saying the lighter CF GT500 is slower than the heavier version is pretty damn stupid. Physics says otherwise.

Dodge has been defying physics for some time now. Denying that, in essence, couldn't be dumber. See sidewall comment above and learn something new.

I never said anything about aero as we've been given downforce numbers at a given speed but never anything about drag in the context of the Base spoiler/Gurney flap vs the GT4 wing. MT reported the following...
"Ford invited us to the adjacent, prepped dragstrip to see if its claim of a "sub-11-second quarter mile" was possible in a base GT500 fitted with the Michelin PS4S tires. Ford chose the base car over the R because it said the PS4S has nearly the same longitudinal grip as the PSC2, and the R's aero drag would produce slower trap speeds at the end of the dragstrip."
From here.

Jim Owens, who jumps all over the place, hints at which version is faster at the strip in the following video, at about the 6 minute mark.


Owens again in Road and Track...
"Owens explained to us that the GT500 will essentially come in two flavors based on how you want to use it. The base-model GT500 will be the quickest in a straight line, while versions equipped with the "Carbon Fiber Handling Package" will be optimized for track duty..... According to Owens, both models will be wickedly quick, but the downforce (and drag) from the Handling Package (error - should read CFTP) car's two-position rear wing might make it slightly slower in a straight line compared to the base model car.
From here.

Just a few "stupid" comments from those that know nothing about the cast in stone internet physics experts that know everything.

The aero won’t be enough to really counteract the benefits of a stickier tire and the much lighter carbon fiber wheel. “Rotational mass” is a big deal in acceleration. I rather shed 40+lbs of rotational mass than 100lbs of static weight.

aero will only start hurting once you are deep into triple digits (120+)

If big enough aero can make you feel like you are hitting a wall at 100 mph. Something as important as a slight wrinkle in the tire coupled with a coupe mph bled off at the top end can certainly out weigh some wheel weight. I doubt this 4S is any less sticky off the line. Sticky straight and sticky in corners are two different types of tire. Real R comp tires are less sticky than an all season on cold street runs too

I know what “big aero” can do.

my point stands. The lighter CFTP 500 with the stickier tires, will and does out accelerate the standard 500 at the 1/4.

it’s aero is not enough to counter weight the benefits of the lower static weight of the car, the MUCH reduced rotational mass/weight and the stickier tires.

Someone should let Ford know the CFTP is faster on the drag strip. They could have left all those base cars they brought to Vegas back in Flat Rock and saved same dough while running faster times.

Someone let these guys know that their real world testing / objective evidence is wrong. It was a dream.

So the obvious trolling is kosher but the guy who may be persona non grata is the priority?

Camaro6 made more sense.

And my point is the Cup2 isn't stickier in this arena... They are designed for road course with mega stiff structure, just like you'll sometimes see base 500's tool CFTP's on the track with amatuers driving using one comparison doesn't work.

you are incorrect bro. I’m actually not trolling right now. Serious. I promise with a cherry on top. The cup2s will grip better than the 4S. No question about it.

the BIGGER story, which most everyone is completely missing, is that not only is the CFTP 120+lbs lighter than the base, but that the CFTP sheds 20lbs of weight on each corner (about 80lbs of sprung mass).

I’ll say it again 80lbs of rotational mass less for the CFTP car.

That is HUGE.

combine that with the grippier Cup2s and you will have a quicker car in the 1/4.
