Your bikes's a 2011 BTW. As for what fenders, look at what these people have done:
Specialized Sirrus Elite 2011 | Bikeshd London
The ad is recent, so you could try contacting the owner and inquiring on the model and tire clearance.

This other one says that in his case, anything over 28mm tire wouldn't fit. I wonder how god of a job this shorter version does anyway.
