Just another perspective of it that I have been thinking about: A car will never run at such high ampage continuous. A motor under load will drain at (I estimate) no more than 20amps on average over a 5-6 minute race. i.e. If I discharge a pack of cells of any type at 20 amp continuous on my discharger, it doesn't take that long - so the motor will drain at that or less on average. (it should, in theory).
So all the C ratings mentioned above are fine, on paper.
But we all know, that the 20amp average above can range from 5amp through to 50amp depending on what the car is doing at any one time. Plotted on a graph it would look like the landscape of the alps. So the cells have got to be able to withstand the peaks - but they'll only be short bursts. My 3200mah 20C do that fine (64 amps).

chris your 3200 are rated 64amps continuos, 96 peak and 128max burst
