The air intakes are thirstier, while the LED indicators that sit just above these intakes follow the two-line layout we've met on the 2017 911 Turbo.
While the turn signals are the kind of typical nitpicking differences Porsche facelifts show, if you pay attention to the gallery below, you'll see the blinkers in action.
Now that the 911 Carrera and Carrera S have gone turbo, the GT3's naturally aspirated 3.8-liter flat-six will be even more of a treat.
As for how this refreshed model affects the GT3 RS, you shouldn't worry too much about a car that comes in 2,000 examples per year. The RS has its customers and, for one thing, all the units being produced this year have already been spoken for.
Zuffenhausen engineers will have to work their magic on the GT3's handling too. For example, when this track-savvy Neunelfer came out in 2013, its rear-wheel steering was a rare feat, but nowadays more and more go-fast machines are turning to this solution.
Since the GT3 must also retain the daily-driving assets of the 911, the task mentioned above is not an easy one.
And yes, time is running out for the development of the 991.2 GT3, since the Porsche is expected to arrive by the end of the year as a 2017 model.
P.S.: We were supposed to talk about how the revamp will bring stuff like Apple CarPlay and other infotainment updates, but we know people don't buy a GT3 for the infotainment.
