Why is there nearly a 1 second difference in the 1/4 mile time between these cars stock? They were identical in Forza 4 but theres nearly a 1 second difference in FM5? Not that I mind really. Just wondering. The WS6 bogs out of the hole even with 4.11 rear gears and the default tires. Camaro runs a 12.9 stock where the WS6 runs about a 13.8.
