Thank God someone else commented on tire sidewall and lateral grip vs straight line grip, I was about to lose my mind. A few items:
1. Both tires are equal as far as straight line grip, but the 4S will launch better because of the sidewall. Road course tires are shit at the drag strip because of the stiff sidewall.
2. Downforce and drag are not the same thing, and they are not proportional. The CFTP will have increased drag compared to the base model, even at low speeds, and even when there is no meaningful downforce.
3. The equation for drag includes an exponent to the second power, so as velocity doubles, drag quadruples. While the rims on the CFTP are lighter, I would argue the drag offsets this benefit.
4. Anyone who understands anything about data understands that 1 data point is worthless. If 1 data point is your gospel I can make a few phone calls and really mess your day up when I have data showing a prius is faster than a GT500.
