Oh, we had a classic epic battle the other night between 4c & 1c with 13.5's. With the exception the the 4c car got hung up a few minutes into the race, it was virtually equal with the tiniest advantage going to the 1c car. The 4c car weighed in at 865g while the 1c was at 730g. The 1c was lighter on it's toes through the corners. Tire wear is down 40%. Once the dust settles, 1c will be the most cost effective class out there. The 1c car won by a lap.
