Interesting comparison between 991.2 GT3, 911GT3 R and 911 RSR
Lap times Lausitzring 3.442km version:
911R: 1:25.9 although in the ADAC GT Masters they lap around 1:22.148
Quite a gap between the GT3 and R considering same engine with same power output (between 11-15 seconds). Or in other words the R overtakes the GT3 every 8. lap.
