Snake03 said:The '03/'04 Cobras are speed limited at 155-160. I initially thought that was due to the chassis getting "light" at those speeds, but that's not the case. It's due to the tire ratings and concerns on driveshaft integrity. My guess is that it's probably similar on the new Mustang.
I agree that the speed limiting is due to the speed rating of the tires. I am sure that Ford is very sensitive about the tires after the Firestone "problems" a few years ago. Basically, Ford is making sure that their vehicles aren't exceeding the tire manufacturer's max specs.
