Does anyone know what all came with the Upfitter Package? I think that's what I have but not 100% sure.

 

The Upfitter Package would have been for a GT going to Shelby from what I understand.
Since you are posting this in the V6 section I am assuming you have a V6.
Besides having a base model there were 3 packages, Pony, Mustang Club of America and Performance later in the year.

 

I did the initial research and got the by option list and density for 2011, and 231 V6 S197s were built with the Upfitter option which on the GT would give it the GT/CS front and rear bumpers with a spoiler delete in prep for the Shelby package. Mine has the CS front and rear bumpers and valance along with the CS spoiler all factory installed from what I can see. The VIN database for window stickers from Ford has been shut down, so I don't know where to verify this at. If this kit was added to my car at the factory then mine is one of 231 made in 2011 and that would make it a rather rare optioned vehicle.

 

Here are pics of my car.

Here is my 2010, the year before the C/S
Before



After







Looks like a Factory car since factory parts were used.
I did mine myself BTW.

 

It wasn't factory option. Someone at a dealership perhaps or the previous owner used the OEM parts from a take off most likely.

 

I like the stripe Siber, works well on the grabber blue.
