Ditto Havy. You can easily verify if the front mats for the f06/f12/f13 are the same...just pull up the carpeted mats in one of the online part databases. If you click on the part number...it will list all other BMW models that use the same part number. Sets of 4 that include the rear (or any rear set of 2) will only list either the f06...or the f12/f13. If you find any that list the front set or only one of the fronts...you will see all 3 models listed (f06/f12/f13).
Example...click the following link to see all of the BMW models that use item
#2 (the front driver's side) in the diagram below:
