Performance Pack Id?

Just recently revieved my 'new' Mustang--a 2014 V6. Two things noticed upon first inspection are: 1) 19" factory wheels; 2) installed strut tower brace--both components of the factory's "Performance Pack". While the selling dealer did not list as such, is there a way that I can definatively confirn (VIN code, etc.) that these are a part of a factory-installed 'Performance Pack'?
 
The only way to be 100% sure is to look at the window sticker as most option packages cannot be determined from the vin# alone. Click the link below enter your vin # in the space provided and download the window sticker. Then you will know for sure.

Thanks! I tried this with no luck... The results check back as "Please Check Back Later - The window sticker has not yet been released for this vehicle". Hmmm?
