Essentially the are the same as long as they are for the manual transmission.
They do NOT fit the Powereshift Automatic.
Ford made a slight change to the brackets in 2014.
So for 2011 - 2013 they are the same and 2014 & 2015 are the same.
A lot of companies make it for the FiST and that one will fit all '14 & '15.
I believe only Steeda makes it for all '11 - '13.
All that being said, I am using a Steeda on my '14 FiST, but it was not as Plug-N-Play.
I hope this helps.
