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'?
