When we installed the Curt Class I hitch # C11367 on a 2014 BMW 4-Series coupe we found that the height of receiver opening was 11-inches above ground level. This is shown in both the linked photo and installation video. Since there are two stock tires sizes offered on the car, P225/50-17 and P255/40-18, the actual height of your vehicle could differ from the one in the video.

The recommended Curt Ball Mount is part # C45521 which has 2-5/8-inches of rise and can be used with a ball like 1-7/8-inch # A-80 or 2-inch # A-82. The next one up in terms of rise is Curt # C45021 which has 4-inches of rise. To account for the normal squat of the car's rear from the trailer tongue weight the 4-inch rise is probably the better option.
