I've used both 87 and 93 on the 2018, i would recommend staying with the 93, the throttle response is better and getting the full 460HP or 420 to the wheels is nice. 87 made the car feel sluggish and jerk from time to time when trying to hit it. This is also with running the car in Sport+ and...
That front end looks amazing with chrome around the top and how the lower matches.
Hoping like everyone else, that Ford will release the lower grill and make the performance parts a power pack upgrade.
