I'm not sure about the Specialized carbon frames, but lots of folks I've known raced on Trek carbon frames (not to mention a big pro team) and they held up well thru thousands of miles of training and racing.

Just remember to take the bike off the roof rack before you drive into the garage! (LOL--a bf made that mistake--amazingly his Trek frame was OK, but his car roof had a crease from where the rack moved, and my garage frame had a dent from his seat!).
